OPINION OF THE COURT
GREENBERG, Circuit Judge.


1
This matter comes on before this court on appeal from the district court's order entered December 14, 1998, granting summary judgment in favor of appellee Synthes (USA) ("Synthes" or "the company") dismissing appellant's complaint asserting claims under the Americans with Disabilities Act, 42 U.S.C. S 12101 et seq. ("ADA"), and Pennsylvania common law. For the reasons we set forth herein, we will affirm the order of the district court.

I. BACKGROUND

2
Synthes, which is in the business of manufacturing and distributing orthopedic and spinal implants and instrumentation, hired appellant Robert Shaner in September 1991 as a senior programmer/analyst in its information services department. In 1992, Synthes gave Shaner a six percent raise despite its practice of capping raises at five percent.


3
In July 1992, Dick Jarvis joined Synthes and became Shaner's superior. In August 1992, Shaner was diagnosed with multiple sclerosis ("MS"). It is undisputed that Shaner did not disclose his ailment to the company until more than a year later, on November 15, 1993.


4
In May 1993, Jarvis gave Shaner his first performance evaluation. The evaluation indicated that the "major problem" with Shaner was that he relied too heavily on quick "fix" solutions without locating underlying problems in the computer systems. It concluded that Shaner "performs his duties as a Senior Programmer" but that he "has not demonstrated that he has the skills of a senior analyst."1 Shaner felt this evaluation was overly critical and he was unhappy with it. Thus, Shaner filed a complaint with the company regarding this evaluation. Shaner suspected that Jarvis did not like him, and it appeared to Shaner that the reason for the criticism was Jarvis's desire to get rid of programmers, such as himself, who had been with Synthes before Jarvis joined the company.


5
On April 5, 1994, Jarvis gave Shaner another evaluation. This evaluation contained critical remarks similar to those in the prior evaluation.2 It indicated that Shaner was not proficient in identifying underlying problems in the computer systems and it concluded that Shaner "has not demonstrated [the] skills of a Senior Analyst." It further indicated that Shaner "displays a negative attitude about his job and does not seem happy with the job he performs." Shaner felt that this evaluation was "almost a carbon copy" of the 1993 evaluation.


6
On April 13, 1994, Shaner filed a charge of disability discrimination with the Equal Employment Opportunity Commission ("EEOC") alleging that Synthes had denied him computer training in the area of "PC Applications."3 He claimed the company had promised him this form of training when he first began his employment and that the training had been given to other programmer/analysts. In January 1994, Shaner had sent a pointed email to Jarvis asking "[i]s there any reason I'm being excluded from EXCEL TRAINING4 when other programmers in this department have taken the training, with YOUR approval [?]" Jarvis sent a responsive email stating"[w]e have not offered Excel training to the AS/400 group [Shaner's group] at this time. You do not need Excel to perform your job."


7
In the summer of 1994, Shaner went on a medical leave of absence for more than one month. Upon his return, the company lightened his work load during month-end closing procedures, which often required long hours on his part. Shaner welcomed this reduced work load. In addition, the company permitted him to miss work every Tuesday morning so he could attend an eleven a.m. water therapy class at a location which was over an hour's drive from the office.5 He continued to attend the water therapy class throughout his employment with Synthes. The company also permitted him to go home early when he was not feeling well.


8
One of Shaner's principal allegations is that various employees, along with Jarvis, frequently turned up the heat in the office despite Shaner's requests that the office be kept cool; the excessive warmth allegedly exacerbated Shaner's MS symptoms. Shaner indicated in his deposition that the heat had been a problem for him even before November 1993, when he advised the company that he suffered from MS. In response to a complaint from Shaner, Mike DiGuglielmo, another of Shaner's superiors, emailed Shaner in May 1994 asking him to provide a doctor's note stating what working conditions were not good for his medical condition. Nevertheless, Shaner did not present the requested note from his doctor until November. The note was not specific as it merely indicated that the temperature in Shaner's work environment should be kept "on the low side."


9
Shaner requested that a "lock box" be placed on the thermostat to prevent employees from repeatedly adjusting the office temperature. Although lock boxes were present on thermostats elsewhere in the building, the company did not place one in Shaner's work area. However, in November 1994, the company relocated Shaner's office to a converted conference room which had its own thermostat so that he could control the temperature in his work space.6 Shaner alleges that, on four or five occasions in 1995, an unknown individual or individuals covertly entered the conference room while Shaner was at lunch and turned the heat all the way up. On these occasions, Shaner returned from lunch and noticed that the room was overly warm, whereupon he adjusted the heat back down.


10
In late 1994, DiGuglielmo told Shaner that it would be in his "best interest" to seek counseling through the company's employee assistance program. Shaner testified that "[f]or the most part" he had a negative attitude at this time, and he voluntarily agreed to attend counseling for assistance with his "work and health problems." The company permitted him to attend counseling sessions on its time and at its expense. According to Shaner, after he had attended several sessions, DiGuglielmo requested that he stop going to counseling, or at least that he stop going on company time. Shaner felt that this request was "inappropriate," inasmuch as DiGuglielmo had asked him to seek counseling in the first place. Shaner nevertheless continued to attend counseling during work hours because he felt that he was benefitting from it.


11
DiGuglielmo prepared a performance evaluation of Shaner for the period ending March 15, 1995.7 According to this evaluation, Shaner "has shown a very negative attitude through out the last year" and he "has not performed to the level expected of a Sr. Program Analyst [and] his analytical skills are suspect." Further, the evaluation stated that Shaner "continues to point fingers at others and make excuses when things go wrong" and "[w]hen he is given assignments he complains about them and they drag out longer than they should."


12
On April 19, 1995, Shaner again went on leave for medical reasons and his condition has prevented him from ever returning to work. Synthes notified Shaner by letter dated October 5, 1995, that it was terminating his employment effective October 19, 1995, "in accordance with our company policy of terminating employment after six months of medical leave of absence." The letter advised Shaner that he could "reapply" for employment should his condition improve. Shaner has been totally and permanently disabled since he left Synthes in April 1995.


13
On April 17, 1996, Shaner filed a second EEOC charge alleging discrimination on the basis of disability and retaliation for the filing of his first EEOC charge. In this second charge, Shaner alleged that he was "harassed" in several respects. He complained about the heat being turned up in the office, and he indicated that he had "received a poor review" in April 1994. He stated that "[a]round the end of 1994, I was told by Mike DiGuglielmo that I had to go to counselling [sic] because I had a `bad attitude.' " He claimed that he was "harassed to the point that my disability was aggravated," which forced him to go on disability and ultimately led to his termination.


14
Shaner filed this action in the district court on June 23, 1997. Count I of the complaint alleged disparate treatment on account of disability in violation of the ADA, 42 U.S.C. SS 12111-12117, "as evidenced by, inter alia, (a) [ ] sudden change in [the company's] performance evaluations of plaintiff, after being informed of plaintiff 's diagnosis of Multiple Sclerosis . . . ; (b) refusing to allow[plaintiff] the special training necessary to the successful completion of his work, while allowing it to other employees;[and] (c) engaging in harassment of plaintiff including the manipulation of the room temperature of his workplace with the knowledge that such behavior would cause plaintiff serious illness or total disability." Count II alleged retaliation in violation of the ADA, 42 U.S.C. S 12203, "as evidenced by, inter alia, (a) [ ] harassment of plaintiff, including turning up the heat in the office so as to cause exacerbation of plaintiff 's condition; (b) transferring plaintiff to a converted closet when he complained about the manipulation of the heat; (c) making false accusations of poor performance by plaintiff; (d) requiring plaintiff to undertake counseling from a third party provider which was harassing and unnecessary; and (e) terminating plaintiff 's employment while he was out on that medical leave." Count III alleged intentional infliction of emotional distress. Following the company's motion for summary judgment, the district court dismissed all claims in an order dated December 11, 1998, and entered on December 14, 1998. Shaner filed a notice of appeal from the district court's order.

II. JURISDICTION and STANDARD OF REVIEW

15
The district court had subject matter jurisdiction over Shaner's ADA claims pursuant to 28 U.S.C. S 1331 and supplemental jurisdiction over his state law claim pursuant to 28 U.S.C. S 1367. We have jurisdiction pursuant to 28 U.S.C. S 1291. Our standard of review is plenary. See Taylor v. Phoenixville Sch. Dist., 184 F.3d 296, 305 (3d Cir. 1999). "Summary judgment is proper where the pleadings, depositions, answers to interrogatories, admissions, and affidavits show there is no genuine issue of material fact and that the moving party is entitled to judgment as a matter of law." Jones v. School Dist. of Philadelphia, 198 F.3d 403, 409 (3d Cir. 1999). We must view the record in the light most favorable to Shaner and draw all reasonable inferences in his favor. Id.

III. DISCUSSION
A. ADA Claims

16
In order to establish a prima facie case of disparate treatment under the ADA, a plaintiff must show "(1) he is a disabled person within the meaning of the ADA; (2) he is otherwise qualified to perform the essential functions of the job, with or without reasonable accommodations by the employer; and (3) he has suffered an otherwise adverse employment decision as a result of discrimination." Gaul v. Lucent Techs., Inc., 134 F.3d 576, 580 (3d Cir. 1998); see also Deane v. Pocono Med. Ctr., 142 F.3d 138, 142 (3d Cir. 1998) (en banc) (citing Gaul). To establish a prima facie case of retaliation under the ADA, a plaintiff must show "(1) protected employee activity; (2) adverse action by the employer either after or contemporaneous with the employee's protected activity; and (3) a causal connection between the employee's protected activity and the employer's adverse action." Krouse v. American Sterilizer Co., 126 F.3d 494, 500 (3d Cir. 1997).


17
We have indicated that the burden-shifting framework of McDonnell Douglas Corp. v. Green, 411 U.S. 792, 93 S.Ct. 1817 (1973), applies to ADA disparate treatment and retaliation claims. See Walton v. Mental Health Ass'n of Southeastern Pa., 168 F.3d 661, 667-68 (3d Cir. 1999); Krouse, 126 F.3d at 500-01; Newman v. GHS Osteopathic, Inc., 60 F.3d 153, 156-58 (3d Cir. 1995). We recently have described the McDonnell Douglas framework as follows:


18
Briefly summarized, the McDonnell Douglas analysis  proceeds in three stages. First, the plaintiff must  establish a prima facie case of discrimination. If the  plaintiff succeeds in establishing a prima facie case,  the burden shifts to the defendant `to articulate some  legitimate, nondiscriminatory reason for the employee's  rejection.' [McDonnell Douglas, 411 U.S. at 802, 93  S.Ct. at 1824.] Finally, should the defendant carry this  burden, the plaintiff then must have an opportunity to  prove by a preponderance of the evidence that the  legitimate reasons offered by the defendant were not its  true reasons, but were a pretext for discrimination. See  Texas Dep't of Community Affairs v. Burdine, 450 U.S.  248, 252-53, 101 S.Ct. 1089, 1093 (1981) (citations  omitted). While the burden of production may shift,  `[t]he ultimate burden of persuading the trier of fact  that the defendant intentionally discriminated against  the plaintiff remains at all times with the plaintiff.' Id.  Our experience is that most cases turn on the third  stage, i.e., can the plaintiff establish pretext.


19
Jones, 198 F.3d at 410.


20
We have stated as follows with regard to the application of the third step of the McDonnell Douglas framework at the summary judgment stage:


21
At this point, the court focuses on whether there is  sufficient evidence from which a jury could conclude  that the purported reasons for defendant's adverse  employment actions were in actuality a pretext for  intentional race [or disability] discrimination. At trial,  the plaintiff must convince the finder of fact `both that  the reason was false, and that discrimination was the  real reason.' St. Mary's Honor Ctr. v. Hicks, 509 U.S.  502, 515, 113 S.Ct. 2742, 2752 (1993) (emphasis in  original). The fact finder's rejection of the employer's  proffered reason allows, but does not compel, judgment  for the plaintiff. Sheridan [v. E.I. DuPont de Nemours  and Co., 100 F.3d 1061, 1066-67 (3d Cir. 1996) (en  banc)].


22
On numerous occasions, we have explained the  plaintiff 's burden at summary judgment on this aspect  of the McDonnell Douglas tripartite framework.  Specifically, in Fuentes v. Perskie, 32 F.3d 759 (3d Cir.  1994), and later in Sheridan, we stated that a plaintiff  may defeat a motion for summary judgment (or  judgment as a matter of law) by pointing `to some  evidence, direct or circumstantial, from which a  fact finder would reasonably either: (1) disbelieve the  employer's articulated legitimate reasons; or (2) believe  that an invidious discriminatory reason was more likely  than not a motivating or determinative cause of the  employer's action.' Fuentes, 32 F.3d at 764; Sheridan,  100 F.3d at 1067.


23
Id. at 412-13.8 "To discredit the employer's proffered reason, [ ] the plaintiff cannot simply show that the employer's decision was wrong or mistaken . . . . Rather, the non-moving plaintiff must demonstrate such weaknesses, implausibilities, inconsistencies, incoherencies, or contradictions in the employer's proffered legitimate reasons for its action that a reasonable fact finder could rationally find them unworthy of credence, and hence infer that the employer did not act for the asserted nondiscriminatory reasons." Fuentes v. Perskie , 32 F.3d 759, 765 (3d Cir. 1994) (citation and internal quotation marks omitted).


24
According to Shaner's complaint, the company's violation of the ADA was "evidenced by" several forms of improper conduct--the denial of training, the poor performance evaluations, the manipulation of office temperature, the relocation of his office, the request that he attend counseling, and the termination. It is unclear from the complaint whether Shaner is claiming that each of these forms of conduct constitute separate "adverse employment actions"--and thus constitute separate substantive ADA claims--or whether he is alleging some of them simply as proof of discriminatory or retaliatory intent. Synthes contends that the only substantive ADA claims properly preserved through a timely EEOC charge were the discriminatory denial of PC applications training (which Shaner raised in his first EEOC charge) and the retaliatory termination (which he raised in the second). According to Synthes, Shaner conceded in the district court that he was not pursuing any other allegations as substantive ADA claims. The district court assumed that Shaner primarily was challenging the denial of PC applications training and the termination, and treated the other alleged conduct as merely evidence of improper intent. Shaner's briefing on this appeal does not clarify the matter; his reply brief simply refers to all of the alleged improper conduct as "evidence" of discrimination or retaliation.


25
We will not determine which of Shaner's allegations were properly preserved through a timely EEOC charge, nor will we dwell on whether Shaner seeks to pursue each of his various allegations as separate substantive ADA claims. Rather, we conclude, considering all of Shaner's allegations, that there is not sufficient evidence to permit a reasonable fact finder to conclude that the company acted with discriminatory or retaliatory intent with respect to any of the challenged conduct. More specifically, with respect to the disparate treatment claim, we hold that Shaner has not presented enough evidence to permit a factfinder either to disbelieve the company's articulated reasons, or to conclude that discrimination on account of disability was the real reason for any of the alleged improper actions. With respect to Shaner's retaliation claim, we hold that Shaner has not presented sufficient evidence to establish a causal connection between any of the alleged improper actions and the filing of his first EEOC charge. Moreover, even assuming a prima facie case of retaliation could be established, we conclude that Shaner has not presented sufficient evidence to permit a fact finder either to disbelieve the company's reasons, or to conclude that retaliation was the real reason, for any of the alleged improper actions.


26
Like many (if not most) employment discrimination plaintiffs, Shaner has no direct evidence to indicate that anyone at Synthes exhibited hostility towards him based on his protected status (as a disabled person) or his protected activity (the filing of his first EEOC charge). The following exchanges from Shaner's deposition are illustrative:


27
Q. From the time you filed the [first EEOC] charge  until you left Synthes, did anyone at Synthes, any  manager at Synthes, including . . . Mike [DiGuglielmo]  and Dick Jarvis, say anything to you about the charge  you had filed with the EEOC in April of 1994?


28
A. I don't remember.


29
Q. Can you identify any conversation or any  statement that you heard about that charge made by  any of those people at this time?


30
A. No, I cannot.


31
Q. Did anyone report to you that any Synthes  manager, including . . . Dick Jarvis or Mike, had made  any statement regarding the EEOC charge that you  had filed in April of 1994 from April 1st, 1994 until the  time you left Synthes?


32
A. I can't remember.


33
. . . .


34
Q. [ ] Do you have any information that Synthes or  any of its managers were retaliating against you  because you filed an EEOC charge in April of 1994 at  any time that you were employed at Synthes?


35
A. Do I have any information? No.


36
. . . .


37
Q. Can you identify any fact or tell me about any  information or any evidence you have which would  indicate to you, in any way, that any manager of  Synthes, at any time, retaliated against you because  you filed an EEOC charge in April of 1994?


38
A. I don't remember any at this time.


39
. . . .


40
Q. Did you ever hear any comments made by any  Synthes manager, including . . . Dick Jarvis or Mike or  any other manager, that indicated that you were  discriminated against because of your disability or your  alleged disability?


41
A. No.


42
Q. Did anyone report to you any comments by any  member of Synthes management which indicated that  you were discriminated against because of your  disability or alleged disability?


43
A. I can't remember any, no.


44
App. at 78, 82.


45
Of course, direct evidence of intent is not required to establish a discrimination claim. See Pivirotto v. Innovative Sys., Inc., 191 F.3d 344, 352 n.4 (3d Cir. 1999). In the absence of direct evidence, a plaintiff may rely on circumstantial evidence to "demonstrate such weaknesses, implausibilities, inconsistencies, incoherencies, or contradictions" in the employer's proffered legitimate reasons so as to permit a reasonable factfinder to infer that the employer did not act for the proffered reasons. See Fuentes, 32 F.3d at 764-65. Accordingly, we will examine in detail the various instances of improper conduct Shaner alleges to determine whether he possibly can show such weaknesses or implausibilities. We conclude that he cannot, and thus his ADA claims cannot survive a motion for summary judgment.9

1. Denial of training

46
Shaner claims that, upon his commencing employment with Synthes, the company promised him that he would receive PC applications training. According to Shaner, he was told that "every opportunity would be available" for such training, and the company's "extensive PC network" was one of the reasons he chose to accept a job at Synthes. Shaner never received the PC applications training he desired, despite his requests for it. He claims that other similarly situated workers received this type of training, including Vincent Jasinnas, who received training in July 1993 on Excel.


47
The company contends that PC applications and Excel were not necessary for Shaner to perform his job. Shaner's testimony fails to counter the company's contention, and indeed tends to support it. At his deposition, Shaner speculated that training in PC applications or Excel "possibly" might have been helpful to him--for example, if a user asked him a question related to PC applications -but he gave no testimony indicating that training in these areas was germane to his regular job functions. Indeed, Shaner answered "No" when asked whether he needed Excel in order to do his job as of January 1994, when he and Jarvis exchanged emails regarding Excel training. Further, Shaner indicated during his deposition that he did not know whether Jasinnas, who received Excel training, actually was doing work involving the use of Excel. Perhaps most significantly, Shaner's testimony shows that the denial of PC applications and Excel training began before November 1993, when he first advised the company of his MS. Accordingly, we can see no basis for a reasonable jury to conclude that Shaner was denied PC applications or Excel training on account of his disability.10


48
Further, there is no evidence of a discriminatory denial of training on the J.D. Edwards system. Shaner's testimony indicates that he received a week-long training seminar on J.D. Edwards in April 1994, along with other Synthes programmers.11 In January 1995, Shaner was instructed to spend four to five hours per week with J.D. Edwards on his own in order to become comfortable with the system. Manuals for J.D. Edwards were available, which Shaner read and understood, and Shaner was advised that he should seek help from another employee who was proficient with the system. Shaner tried to comply with the company's instruction, but he found the system difficult to learn, although he was a computer professional. Shaner never asked anyone for help, because he felt it would be "humiliating" to do so, and he never indicated to anyone that he could not or would not learn the system on his own. He admitted in his deposition that he simply failed to carry out his superiors' expectation that he familiarize himself with J.D. Edwards. As with PC applications training, we see no grounds for a reasonable jury to conclude that the company acted with discriminatory intent with respect to its decision not to provide Shaner with additional formal training on J.D. Edwards.12

2. Performance evaluations

49
Shaner's allegation that there was a "sudden change" in his performance evaluations after he informed the company that he suffered from MS is not supported, and indeed is contradicted, by the record evidence. Shaner's May 1993 performance evaluation--which Shaner himself viewed to be highly critical--was given several months before he informed Synthes about his disease and nearly a year before he filed his first EEOC charge. According to Shaner's testimony, he suspected at the time that the motive behind the criticisms in the 1993 evaluation was Jarvis's desire to force out programmers who pre-dated Jarvis's arrival at Synthes. While this motive may not have been benevolent, it could not have been based on Shaner's disability, which had not yet been made known to the company. According to Shaner's testimony, his next evaluation, in April 1994-which he received prior to the filing of his first EEOC charge, was a "carbon copy" of the 1993 evaluation. A subsequent evaluation in March 1995, like the two prior ones, indicated that Shaner was not performing to the level expected of a senior analyst. In short, the record shows that Shaner's performance evaluations contained similar criticisms both before and after he made the company aware that he suffered from MS and before and after he filed his first EEOC charge.13


50
Under these circumstances, there is simply no evidence that any of these evaluations was causally linked to the filing of Shaner's first EEOC charge or that any of them was motivated by discriminatory or retaliatory intent. We have indicated that temporal proximity between the employee's protected activity and the alleged retaliatory action may satisfy the causal link element of a prima facie retaliation claim, at least where the timing is "unusually suggestive of retaliatory motive." See Krouse, 126 F.3d at 503 (internal quotation marks omitted); Woodson, 109 F.3d at 920. Yet the timing of the performance evaluations in this case is anything but suggestive, inasmuch as Shaner received the 1993 and 1994 evaluations prior to the filing of his first EEOC charge, and the 1995 evaluation was prepared nearly a year after the filing of the charge.


51
Moreover, although "mere passage of time is not legally conclusive proof against retaliation," we have indicated that the passage of a long period of time between protected activity and an alleged retaliatory action weighs against a finding of a causal link where there is no evidence of retaliatory animus during the intervening period. See Krouse, 126 F.3d at 503-04 ("Absent evidence of intervening antagonism or retaliatory animus, we conclude that the passage of time [between the filing of plaintiff 's charge and the alleged retaliatory action] in this case is conclusive and that [plaintiff] failed to establish a causal link as a matter of law."); Woodson, 109 F.3d at 920-21. The record does not support a finding that there was an intervening retaliatory animus so as to establish a causal connection between the filing of Shaner's first charge and the 1995 evaluation, particularly in view of the circumstance that the three evaluations were consistent.


52
We also make the following observation with respect to performance evaluations. While it is possible that a manager might make a poor evaluation to retaliate against an employee for making an EEOC charge, still it is important that an employer not be dissuaded from making what he believes is an appropriate evaluation by a reason of a fear that the evaluated employee will charge that the evaluation was retaliatory. In this regard, we are well aware that some employees do not recognize their deficiencies and thus erroneously may attribute negative evaluations to an employer's prejudice. Accordingly, in a case like this in which the circumstances simply cannot support an inference that the evaluations were related to the EEOC charges, a court should not hesitate to say so.

3. Office temperature

53
According to Shaner's testimony, prior to the relocation of his office, he frequently saw employees, including Jarvis, adjusting the thermostat in the area of the building where Shaner and others worked. He admitted during his deposition that he had no evidence that any of these people were changing the thermostat in order to harm him. Indeed, he responded "I would think so" when asked whether these people were adjusting the thermostat simply because they were uncomfortable with the office temperature, and he indicated that he "disagreed" with others regarding the appropriate temperature.14 Most significantly, Shaner testified that the thermostat frequently was adjusted too high for his liking prior to November 1993, when he first informed the company that he suffered from MS. Thus, with respect to the period prior to the relocation of Shaner's office, we see no basis for a finding that anyone adjusted the temperature with discriminatory or retaliatory intent, and no evidence of a causal link between Shaner's problems with office temperature and the filing of his first EEOC charge.15


54
According to Shaner, after his office was relocated, there were four or five instances when an unknown individual or individuals turned the heat all the way up while he was at lunch. These isolated incidents do not in themselves rise to the level of adverse action upon which to base a claim for disparate treatment or retaliation. See Mondzelewski v. Pathmark Stores, Inc., 162 F.3d 778, 787 (3d Cir. 1998) ("[M]inor or trivial actions that merely make an employee `unhappy' are not sufficient to qualify as retaliation under the ADA . . . ."). Even if a factfinder could infer that these incidents were motivated by hostility toward Shaner's disability, we do not believe, in light of all the evidence, that these incidents provide a basis for a rational finding that any of the company's other actions were motivated by discriminatory or retaliatory intent.16

4. Termination

55
Shaner does not challenge the company's general policy requiring termination of employees who are on medical leave for six months. Nor does he dispute that he was permanently and totally disabled when he went on leave in April 1995 and that he has been unable to work since. Shaner's argument is that the company intentionally or recklessly caused an exacerbation of his MS through its discriminatory and retaliatory treatment--including the manipulation of the office temperature--so as to compel him to take a leave of absence, thereby allowing the company to apply its termination policy as a pretext for retaliation.17 To support this argument, Shaner cites his own hearsay testimony that another employee told him that the company began removing and rearranging things in Shaner's office a day or two after Shaner went on leave in April 1995. Shaner contends that the company did not know at that time how long he was going to be absent.


56
We have no trouble concluding that a reasonable factfinder cannot accept Shaner's theory that the company intentionally or recklessly caused his MS to worsen. Contrary to the inference which Shaner seeks to raise, the evidence shows that the company made substantial efforts to accommodate him. When Shaner returned from hisfirst leave of absence in 1994, the company lightened his month-end work load and allowed him to attend water therapy sessions during work hours. In November 1994, the company moved him to an office with its own thermostat so that he could control the temperature in his work space. The company also permitted him to leave work early when he was ill and allowed him to attend counseling sessions during work hours. Considering all the evidence, there is no basis for a factfinder to conclude that the sixmonth policy was applied as a pretext for retaliation.

Further, the evidence does not establish a causal link between the termination and the filing of Shaner's first EEOC charge. The termination took place approximately a year and a half after the filing of the charge, and the evidence does not support a finding that there was such intervening discrimination or retaliatory harassment as to permit an inference that the termination was linked to the filing of the charge. See Krouse, 126 F.3d at 503-04 (affirming summary judgment for employer on retaliation claim where there was no evidence of antagonism or retaliatory animus during nineteen-month period between the filing of the plaintiff 's charge and the alleged retaliatory action). Although Shaner contends that the company planned on firing him as soon as he began his leave in April 1995, the fact remains that he was not fired until six months later, pursuant to a neutral policy. There is no basis for a finding of retaliation here. In sum, the district court properly granted summary judgment with respect to Shaner's ADA claims.

B. Emotional Distress

58
We further conclude that there is not sufficient evidence to establish a claim for intentional infliction of emotional distress under Pennsylvania law. That tort is defined as follows:


59
One who by extreme and outrageous conduct  intentionally or recklessly causes severe emotional  distress to another is subject to liability for such  emotional distress, and if bodily harm to the other  results from it, for such bodily harm.


60
Hoy v. Angelone, 720 A.2d 745, 753 (Pa. 1998) (quoting Restatement (Second) of Torts S 46).18 "[C]ourts have been chary to allow recovery for a claim of intentional infliction of emotional distress. Only if conduct which is extreme or clearly outrageous is established will a claim be proven." Id. at 753-54. The Hoy court rejected an emotional distress claim arising from workplace sexual harassment involving sexual propositions, physical contact with the plaintiff 's knee, off-color jokes, regular use of profanity, and the posting of a sexually suggestive picture. See id. at 754-55. In so ruling, the court stated that "the conduct exhibited . . ., while unacceptable, was not so extremely outrageous . . . that would allow for recovery under this most limited of torts." Id. at 755.


61
We will assume that conduct which is intended to cause a worsening of a disabled person's physical symptoms may qualify as "extreme or clearly outrageous." Nevertheless, viewing the record in the light most favorable to Shaner, we do not find sufficient evidence to establish such a claim here. Shaner's most serious allegation--manipulation of the office temperature with intent to cause him harm or reckless disregard for his health--is simply not supported by the record, which indicates that others adjusted the temperature simply for their own comfort.19 Accordingly, Shaner's emotional distress claim cannot survive summary judgment.20

IV. CONCLUSION

62
For the reasons set forth above, the district court's order entered December 14, 1998, granting summary judgment in favor of Synthes will be affirmed.



Notes:


1
 The evaluation rated Shaner's performance on a scale of 1 to 4, with 4 being "superior," 3 being "above average," 2 being "average," and 1 being "below average." Shaner received a 3 in the category of "assignments and results achieved," a 2.8 in "qualitative," and a 2.8 in "overall performance."


2
 In this evaluation, Shaner was graded "meets expectation" in the category of "assignments and results achieved" and "marginal" in the categories of "qualitative" and "overall performance." A "marginal" grade indicated that Shaner "does not consistently meet objectives."


3
 According to Shaner's brief, he first contacted the EEOC on March 30, 1994. There is nothing in the record to indicate that Synthes became aware of Shaner's contact with the EEOC until after Shaner filed his charge on April 13, 1994.


4
 Excel training involved the operation of PC applications.


5
 Shaner was required to make up the missed time on other days.


6
 The thermostat in this room also affected the temperature in other employees' nearby work areas, which somewhat limited Shaner's ability to control the temperature.


7
 In this evaluation, Shaner was graded "marginal" in the categories of "assignments and results achieved" and "overall performance," and "below expectations" in the category of "qualitative." "Below expectations" indicated that Shaner "frequently does not meet objectives."


8
 We recently have made clear that a plaintiff 's ultimate burden in a retaliation case is to convince the factfinder that retaliatory intent had a "determinative effect" on the employer's decision. See Woodson v. Scott Paper Co., 109 F.3d 913, 931-35 (3d Cir. 1997); Krouse, 126 F.3d at 501 ("The plaintiff must prove that retaliatory animus played a role in the employer's decision-making process and that it had a determinative effect on the outcome of that process.") (citing Woodson).


9
 We have indicated that "a discrimination analysis must concentrate not on individual incidents, but on the overall scenario." See Woodson, 109 F.3d at 921 (citation omitted). Nevertheless, where, as here, a plaintiff alleges that discrimination or retaliation is evidenced by discrete categories of conduct, we believe that some examination of each category is necessary in order to assess the merits of the case. See id. We will examine each of the categories of improper conduct alleged by Shaner, keeping in mind our admonition that "[a] play cannot be understood on the basis of some of its scenes but only on its entire performance." Id. (citation omitted).


10
 According to Shaner's brief, "the record revealed that all the programmers except Shaner had received PC Applications training, causing even the other programmers to wonder why plaintiff was being excluded." We do not see any support in the record for this contention. Shaner's brief cites only to the testimony of a Synthes employee, Crystal Dean. However, Dean was referring not to PC Applications training but to another form of training--on a system called J.D. Edwards--when she testified that Shaner was denied training that others had received. ("[Shaner] was the last of the programmers who had not received training for J.D. Edwards.") (emphasis added). Yet, Shaner conceded at his deposition that he received a week of J.D. Edwards training along with other programmers, and Dean testified that she was unaware that Shaner had received this training. Indeed, Dean conceded that she had no personal knowledge as to the J.D. Edwards training received by any of the programmers, including Shaner, and she indicated that her knowledge regarding denials of training was based almost entirely on what Shaner had told her. Accordingly, Dean's testimony does not provide a basis for inferring discriminatory intent in relation to the denial of PC applications training, or any other form of training.


11
 Shaner also contends that he wrongfully was excluded from meetings of the "SIBIS" team, which was involved in programming the J.D. Edwards system. Yet, Shaner testified that his exclusion from the SIBIS team began when Jarvis joined the company, which was well before Shaner disclosed his illness to the company in November 1993.


12
 Our conclusions regarding PC applications training and J.D. Edwards training are further bolstered by Shaner's testimony that the company in fact provided him with various training during the course of his employment, including the week-long seminar on J.D. Edwards. Further, the company paid for Shaner to attend periodic seminars with an organization called the "Delaware Valley Computer Users Group." The fact that Shaner received some training from the company severely undermines his claim that the company deprived him of other forms of training on account of his disability.


13
 Indeed, prior to November 15, 1993, Shaner complained to his MS support group that he had received an unfairly critical performance review from his employer.


14
 Shaner's testimony in this regard is corroborated by testimony from other Synthes employees. Denise Arms-Sadowski testified that she had a low tolerance for cold temperatures and often asked Jarvis to raise the heat. She also testified that there were other employees who complained about the office being too cold. According to George Felix, "Bob [Shaner] would go to the thermostat and turn the heat down. There were employees that complained that it was then too cold in the office and they would turn the heat back up." Indeed, at oral argument before us, Shaner's counsel stated that "it is clear from the evidence on the record that they were raising the heat to over 75 degrees for the comfort level of other employees." Oral Argument Tr. at 7 (emphasis added). Of course, we do not suggest that this case turns on an inquiry as to how far an employer must go to make a reasonable accommodation under the ADA to a disabled person at the expense of other employees. See Kralik v. Durbin, 130 F.3d 76, 80-84 (3d Cir. 1997).


15
 We do not see how an intent to discriminate or retaliate can be inferred from the fact that Shaner was required to work under the same temperature conditions as other employees.


16
 Shaner's claim that the company acted with retaliatory intent in relocating his office is entirely without merit. The company was responding to Shaner's own complaints about office temperature, and Shaner conceded at his deposition that the company "attempted to accommodate me" by moving him to a room with its own temperature control. Indeed, according to Shaner's testimony, he and DiGuglielmo agreed prior to the move that it would be better for him to work in an area where he could control the temperature. Further, Shaner's allegation that the conference room to which he was moved was a "converted closet" is completely at odds with his own deposition testimony. Although the conference room was once used for storage, it also had been an office for two consultants, and it contained windows looking out onto a hallway. We simply see no basis for a finding that the office relocation was causally linked to the filing of the EEOC charge or that the relocation was made with retaliatory intent.
We also see no evidence of retaliatory intent with respect to DiGuglielmo's request that Shaner attend counseling. Shaner voluntarily attended the counseling because he felt that it would be beneficial to him. As with the relocation of Shaner's office, the evidence shows only that the company was making efforts to help Shaner, rather than to discriminate or retaliate against him. The very purpose of the ADA would be undermined if, in the context presented here, we were to view the company's attempts to aid or accommodate Shaner as evidence of retaliatory treatment.


17
 Shaner's brief argues as follows:
Focusing entirely on Synthes's `non-discriminatory reason' for firing  Robert Shaner (Synthes's alleged policy of firing any employee out  on medical leave for more than six months), the court below  accepted Synthes's statements that they always adhered to the six  month policy, disallowing that Shaner need not have offered  evidence challenging the existence of such a policy, since he was  charging that Synthes had caused his disability so that it could  apply the policy to him. The punctilious procedural perfection of  Synthes's use of that policy is irrelevant.
Appellant's Br. at 37-38.


18
 The Pennsylvania Supreme Court has not expressly adopted section 46 of the Restatement. See Hoy, 720 A.2d at 753 n.10. In Hoy, the court assumed the existence of the tort under Pennsylvania law and concluded that the plaintiff had failed to establish a right of recovery. See id.


19
 Although Shaner testified as to four or five occasions when someone turned the heat all the way up in the conference room while he was at lunch, we do not believe that these isolated incidents rise to the level of outrageous conduct, even assuming that the perpetrator was aware of the effect of heat on Shaner's MS. Such isolated office pranks do not meet the threshold of this "most limited of torts." See Hoy, 720 A.2d at 755.


20
 The district court held that Shaner's emotional distress claim was barred by the Pennsylvania Workers' Compensation Act, and further indicated that any heat-related aggravation of Shaner's MS would be a work-related injury compensable only through workers' compensation. In light of our disposition, we need not address these issues.
