No. 19CA0059, HCA-HealthONE v. Colo. Dept. of Labor and
Employment — Labor and Industry — Colorado Minimum Wage
Order

     A division of the court of appeals considers whether the

Colorado Minimum Wage Order Number 35 (MWO) entitled a

hospital employee to compensation during designated meal periods.

The division holds that the MWO is not ambiguous and its plain

language provides that a meal period is compensable unless it is

both “uninterrupted” and “duty free” — which means completely

relieved of all duties. Because the record shows that the employee

had duties during some meal periods at issue, the division holds

that the employee was entitled to compensation for those particular

meal periods. Therefore, the division affirms in part, reverses in

part, and remands for further proceedings.

*Sitting by assignment of the Chief Justice under provisions of Colo. Const. art.
VI, § 5(3), and § 24-51-1105, C.R.S. 2019.
¶1    Plaintiff, HCA HealthONE LLC, d/b/a North Suburban Medical

 Center (the Hospital), appeals the district court’s order affirming the

 final agency decision holding that the Hospital owed wages and

 penalties to a former employee for work she performed during

 designated meal periods. The decision, issued by defendant, the

 Colorado Department of Labor and Employment, Division of Labor

 Standards and Statistics (the Division), determined that those

 periods were compensable under the Colorado Minimum Wage

 Order Number 35, 7 Code Colo. Regs. 1103-1(7) (effective Jan. 1,

 2020-Mar. 16, 2020), https://perma.cc/GA3G-4ZUP (MWO).

¶2    Addressing a novel question, we hold that the MWO is not

 ambiguous and its plain language provides that a meal period is

 compensable unless it is both “uninterrupted” and “duty free.”

 Because the Division correctly interpreted the MWO, and because

 the record supports the Division’s decision that the employee here

 had duties during her meal periods (with the exception of one

 timeframe), we affirm in part, reverse in part, and remand for

 further proceedings.




                                    1
                         I.      Factual Background

¶3    The underlying agency action was initiated by the former

 employee, the claimant and nominal party here, Lynne Witt.1

                    A.        Witt’s Job Responsibilities

¶4    Witt worked twelve-hour shifts from 6:00 a.m. to 6:30 p.m. in

 the Hospital’s freestanding emergency room laboratory from 2013 to

 2016. As a laboratory medical technologist, she ran tests on

 patient specimens, maintained analyzers, ran quality control,

 logged in specimens, and conveyed critical results to caregivers.

¶5    The lab was staffed around the clock, seven days a week, so

 that tests for acutely ill patients could be performed without delay.

 During her shifts, the small team at the Hospital relied on Witt “for

 everything regarding the laboratory; there [was] no other person to

 go to.”




 1Witt did not participate in the district court, nor has she
 participated in this appeal. The Hospital does not assert any claims
 against her; she was included as a nominal party pursuant to
 section 24-4-106(4), C.R.S. 2019, because she was a party to the
 agency action.

                                        2
                          B.   Meal Periods

¶6    In accordance with the Hospital’s policy, Witt took thirty-

 minute meal periods. The duties and restrictions she had during

 those periods led to her wage complaint.

                1.   The Hospital’s Meal Period Policy

¶7    The Hospital’s policy provided as follows:

           Patient care needs permitting, meal periods
           must be at least thirty (30) uninterrupted
           minutes in duration and are scheduled for
           employees working five (5) or more consecutive
           hours. Employees must be relieved of all work
           duties during the meal period. . . . Meal period
           interruptions that are considered “de minimis”
           will not be considered compensable time . . . .

           ....

           Meal periods are considered unpaid time and
           must be recorded in the timekeeping system.
           Employees will not be compensated for meal
           periods unless the meal is interrupted to
           perform work-related duties. If a non-exempt
           employee is interrupted, or misses a meal
           period to perform work, the employee will be
           paid for the entire scheduled meal period.
           Interruptions which are considered de minimis
           do not require full meal period payment. With
           prior management approval, an employee may
           consume an “on duty meal” while performing
           duties outside of clinical or patient care areas.
           The “on duty meal” time is paid.




                                   3
¶8     To receive payment for missed or interrupted meals, employees

  were instructed to clock in, notify their manager, and/or submit a

  timekeeping adjustment form. Witt used the timekeeping system

  on occasion to obtain compensation for interrupted meal periods.

  None of those occasions is in dispute here.

                     2.    Use of Witt’s Meal Periods

¶9     During her meal period, Witt could generally step out of the

  lab, use the breakroom, watch TV, read, make personal calls, eat,

  and rest. As she stated in her wage complaint, however, she was

  the only laboratory technologist on duty during her shifts. So, Witt

  was “basically ‘on call’” during meal periods. This meant she was

  required to (1) carry the lab phone and respond to all lab calls;

  (2) leave a sign at the lab instructing nurses to call her to return to

  work when they would drop off a specimen; and (3) answer and

  handle routine business calls for the lab, including answering

  questions from doctors, nurses, and paramedics about lab tests,

  equipment, and instruments.

¶ 10   Additionally, to ensure that Witt could promptly respond to

  these tasks, and because the lab phone she carried did not work

  outside of the building, she was not allowed the leave the Hospital


                                     4
  facility during her meal periods. Consequently, she could not

  pursue personal activities like running errands, going for a walk, or

  simply sitting at the picnic table just outside the facility.

                            II.        Procedural History

                                  A.     Agency Action

                       1.         Witt’s Wage Complaint

¶ 11   Witt filed a wage complaint with the Division on October 14,

  2015, pursuant to section 8-4-111, C.R.S. 2019, seeking payment

  from the Hospital for all meal periods for which she had not been

  compensated.

¶ 12   Witt contended she was “on call” during her meal periods. She

  said that Hospital management “insist[ed]” that she clock out for

  meals and clock back in when she is interrupted. But, because

  clocking back in led to overtime pay, and the Hospital “[did] not

  want to pay” for overtime, managers “require[d]” her to try to take

  another meal break later in the shift. According to Witt, that was

  not practical because it would have required taking a meal break as

  much as eight to ten hours after her shift began. Witt also

  explained that she “did not want to give up her lunch break”

  because


                                            5
            I’m very hungry by that point; it is my one
            meal in the whole 12 and a half hours and I
            need to eat that meal even if that means gulp
            it down.

            So I did not . . . if [an interruption] was
            something I could handle in, you know, 1 to 15
            minutes then I was not going to clock back in
            to do that because I need to eat my food,
            otherwise my hot food is going down the
            kitchen sink or in the garbage can and that’s
            my meal for the day. So I was not wanting to
            give up that food break. It’s not a matter of
            just sitting in the breakroom and watching
            TV[,] it’s a matter of putting food in your
            stomach so you don’t faint.

¶ 13   Witt further alleged that her managers had “threatened” her to

  stop incurring overtime pay. According to Witt, her supervisor told

  her that the Hospital’s meal period policy did not permit

  compensation for minor interruptions, and that she must stop

  clocking in when they occurred — that is, she must clock in again

  only to conduct lab testing.

                     2.    The Hospital’s Response

¶ 14   After Witt filed her complaint with the Division, the Hospital

  worked with her to address her concerns. By the end of 2015, the

  hospital implemented a new policy: Witt was no longer required to

  carry a phone or respond to non-emergency calls during her meal



                                    6
  periods. Instead, a charge nurse would handle the phone and not

  interrupt her meal periods absent a “life critical emergency.” After

  this change, Witt believed the meal periods were “fair.” Hence, her

  wage claim covered only meal periods between “October of ’13 to

  December 30th of ’15 when they changed the policy.”

¶ 15   The Division notified the Hospital of Witt’s claim in writing on

  January 28, 2016, solicited information for the investigation, and

  informed the Hospital that the notice served as a written demand

  for wages under section 8-4-111(5). After receiving an extension of

  time, the Hospital responded on February 25, 2016.

¶ 16   Among other things, the Hospital asserted that “while it has

  no reason to believe that Ms. Witt was not properly compensated,” it

  had agreed to compensate her for “the meal periods she alleges that

  she took (i.e., was not paid for) and that she alleges were

  interrupted for pay periods ending 11/1/13 through 2/13/16 to

  satisfy any concerns on this issue.” “[T]o fully resolve this matter,”

  the Hospital paid Witt for all uncompensated meal periods in that

  timeframe, which totaled 136.




                                     7
                            3.   The Citation

¶ 17   The Division’s compliance investigator issued a “Notice of

  Determination and Enclosed Citation” (Citation) on December 14,

  2016. After quoting the MWO, the Citation (1) credited evidence

  that Witt was “regularly not paid for ‘on duty’ meal breaks” and had

  to “remain on call” during the relevant meal period; (2) found that

  the Hospital violated the MWO by not compensating her for all such

  periods; and (3) concluded that she “should have been compensated

  for all ‘on-duty’ meal breaks, whether she was interrupted or not.”

  The Citation applied to meal periods through February 13, 2016.

¶ 18   The Citation also determined that the Hospital had paid all

  wages owed by the time of the Citation. Yet, because the Hospital

  had not paid those wages within fourteen days of the written

  demand, the Citation advised the Hospital that it was required by

  statute to pay a penalty to Witt. The compliance investigator

  calculated this penalty to total $4210, but she exercised the

  Division’s statutorily granted discretion to reduce the penalty by

  50 percent (the maximum amount) because the Hospital had paid

  Witt the wages due before the Citation.




                                    8
                   4.   The Hearing and The Decision

¶ 19   The Hospital appealed the Citation through the administrative

  process, asserting that the Division had misinterpreted the MWO

  and had applied an unwritten rule in violation of the State

  Administrative Procedure Act (APA), §§ 24-4-101 to -108, C.R.S.

  2019. A Division hearing officer held a hearing, at which Witt

  testified as well as the Hospital’s Director of Laboratory Services

  and Vice-President for Human Resources.

¶ 20   After receiving the evidence, the hearing officer issued a

  lengthy “Decision and Order” (Decision), agreeing that Witt’s meal

  periods at issue were compensable under the MWO. In particular,

  the hearing officer concluded that they were compensable under a

  “stringent” reading of the MWO’s terms as well as under the more

  lenient “predominant benefit test” used by some federal courts

  when considering a federal regulation related to the Fair Labor

  Standards Act (FLSA), 29 U.S.C. §§ 201-219 (2018). (The Hospital

  had advocated for the federal test.)

¶ 21   The Decision principally concluded that (1) “Witt was engaged

  in substantial work-related activities during her meal periods”;

  (2) the record showed that she was “on duty (in other words that


                                     9
  her meal breaks were not uninterrupted and duty free) during her

  meal periods”; and (3) and the compliance investigator had engaged

  in adjudication, not rulemaking, when resolving Witt’s claim.

                           B.   Judicial Review

¶ 22   The Hospital sought judicial review of the Decision in the

  district court. Affirming the Decision, the court ruled that (1) “in its

  application of the plain language of the Wage Claim Act and MWO,

  the Division did not apply an erroneous legal standard, nor did it

  act arbitrarily and capriciously, nor contrary to any statutory or

  constitutional right”; (2) “the Division did not err in determining

  that Ms. Witt’s meal periods constituted compensable on-duty meal

  periods under the MWO” and “the Division based its Decision on

  sufficient competent evidence”; (3) the Hospital failed to overcome

  the presumption favoring the regularity and validity of

  administrative proceedings and favoring the Division when resolving

  any reasonable doubts; (4) the Decision “is consistent with the

  relevant statutory and regulatory language and abides by the

  applicable statutory scheme (e.g. the [Wage Claim] Act and MWO)”;

  and, therefore, (5) there was no basis for setting aside the Decision.




                                     10
             III.   Did the Division Err in its Interpretation
                         and Enforcement of the MWO?

¶ 23   On appeal to this court, the Hospital contends that the

  Division applied an erroneous interpretation of the MWO. The

  Hospital maintains that the MWO is ambiguous and, therefore, we

  should rely on federal authority construing a FLSA regulation.

  Doing so, the Hospital says, leads to the conclusion that Witt’s meal

  periods were not compensable.

¶ 24   The Hospital has presented thoughtful points. Still, with one

  exception, we are not persuaded to set aside the Decision. Instead,

  we conclude that, under the MWO’s plain terms, Witt’s meal periods

  at issue were compensable. Hence, it is neither necessary nor

  appropriate to rely on federal law. With respect to one timeframe

  (January to February 2016), however, we reverse and remand

  because the Decision did not adequately address whether the meal

  periods were compensable.

                          A.    Legal Framework

¶ 25   The General Assembly has empowered the Division to

  promulgate regulations, among them wage orders. Brunson v. Colo.

  Cab Co., LLC, 2018 COA 17, ¶ 13; see § 24-1-121(1), C.R.S. 2019.



                                     11
  One such regulation, the MWO, implements the Colorado Wage

  Claim Act, §§ 8-4-101 to -123, C.R.S. 2019, and regulates the

  wages, hours, working conditions, and procedures for certain

  employers. See Brunson, ¶¶ 3, 13.

¶ 26   The MWO has been amended over time, but not in a manner

  relevant here. The pertinent MWO provision states:

            Employees shall be entitled to an
            uninterrupted and “duty free” meal period of at
            least a thirty minute duration when the
            scheduled work shift exceeds five consecutive
            hours of work. The employees must be
            completely relieved of all duties and permitted
            to pursue personal activities to qualify as a
            non-work, uncompensated period of time.
            When the nature of the business activity or
            other circumstances exist that makes an
            uninterrupted meal period impractical, the
            employee shall be permitted to consume an
            “on-duty” meal while performing duties.
            Employees shall be permitted to fully consume
            a meal of choice “on the job” and be fully
            compensated for the “on-duty” meal period
            without any loss of time or compensation.

  Colo. Minimum Wage Order No. 35, 7 Code Colo. Regs. 1103-1(7).

                        B.   Standard of Review

¶ 27   When considering the Decision, we apply the same standard of

  review applied by the district court. Gessler v. Grossman, 2015

  COA 62, ¶ 38, aff’d, 2018 CO 48. That is, “review is limited to the


                                   12
  decisions of the hearing officer and the [agency].” Marshall v. Civil

  Serv. Comm’n, 2016 COA 156, ¶ 10. Our task is a limited one — we

  may not reweigh the evidence before the Division. See Bd. of Cty.

  Comm’rs v. O’Dell, 920 P.2d 48, 53 (Colo. 1996); Stor-N-Lock

  Partners # 15, LLC v. City of Thornton, 2018 COA 65, ¶ 22.

¶ 28   Judicial review of the agency action in this case is governed by

  section 24-4-106. As relevant to the Hospital’s claims, a reviewing

  court may set aside an agency action if it is arbitrary or capricious,

  in excess of statutory authority, not in accord with the procedures

  or procedural limitations of the APA or as otherwise required by

  law, an abuse or clearly unwarranted exercise of discretion,

  unsupported by substantial evidence, or otherwise contrary to law.

  § 24-4-106(7)(b); see Rocky Mountain Retail Mgmt., LLC v. City of

  Northglenn, 2017 CO 33, ¶ 29.

                              C.    Analysis

                     1.   Interpretation of the MWO

¶ 29   We review administrative regulations de novo. Brunson, ¶ 10.

  “Our primary task in this review is to give effect to the promulgating

  body’s intent.” Id. In construing a regulation, we apply the same

  rules of construction that we would apply in interpreting a statute.


                                    13
  Id. As with a statute, if the regulation’s language is clear and

  unambiguous, we do not resort to other rules of construction. Id.

¶ 30   In the absence of a statutory or regulatory definition, we

  construe a term according to its ordinary or natural meaning. See

  Cowen v. People, 2018 CO 96, ¶ 14 (construing a statute). When

  determining the plain and ordinary meaning of words, we may

  consider a definition in a recognized dictionary. Id. (citing a case

  that relied on Black’s Law Dictionary).

¶ 31   As noted, the MWO defines a non-compensable meal period as

  one that is “uninterrupted and ‘duty free.’” Colo. Minimum Wage

  Order No. 35, 7 Code Colo. Regs. 1103-1(7). If that were not clear

  enough, the MWO states further that “employees must be completely

  relieved of all duties and permitted to pursue personal activities to

  qualify as a non-work, uncompensated period of time.” Id.

  (emphasis added). Therefore, if an employee has a duty to the

  employer during the period at issue, the period is compensable.

¶ 32   A “duty” is a “legal obligation that is owed or due to another

  and that needs to be satisfied; that which one is bound to do, and

  for which somebody else has a corresponding right.” Black’s Law

  Dictionary 637 (11th ed. 2019). The Hospital’s counsel at oral


                                    14
  argument in this appeal agreed that, under this definition, Witt had

  duties during her meal periods (e.g., she had to respond to phone

  calls to the lab). See also Webster’s Third New International

  Dictionary 705 (1969) (“Duty” includes “obligatory tasks, conduct,

  service, or functions enjoined by order or usage according to . . .

  occupation or profession.”).2

¶ 33   Even so, the Hospital contends that the MWO’s language is

  ambiguous because “duty” and “duties” are susceptible of more

  than one interpretation. The Hospital posits that “duties” in this

  context could mean either “(1) those primary tasks which the

  employee was hired to perform (here, lab testing) or (2) any ancillary

  work-related activity (here, carrying a phone and remaining on

  site).”3 Given this alleged ambiguity in the MWO, the Hospital urges

  us to apply the predominant benefit test used by some federal

  courts when interpreting federal law pertaining to employee meal

  breaks under the FLSA. See, e.g., Castaneda v. JBS USA, LLC, 819


  2 We except the meal periods in 2016 from this conclusion, for
  reasons we will discuss later in the opinion.

  3 Additionally, the Hospital asks us to consider the phrase “on-call
  meal periods,” which the Hospital encloses in quotation marks. But
  that phrase is not in the MWO.

                                    15
  F.3d 1237, 1253 (10th Cir. 2016). The predominant benefit test

  asks whether the employee is primarily engaged in work-related

  duties such that the meal time is spent predominantly for the

  employer’s benefit. Id.

¶ 34   Nothing in the plain meaning of the term “duty,” however,

  suggests a distinction between “primary” obligations and “ancillary”

  obligations. If the employee is obligated to perform the task —

  subject to possible discipline if he or she refuses — the task is a

  duty. Indeed, at least one federal court has agreed with this strict

  reading of the MWO. See Sobolewski v. Boselli & Sons, LLC, 342 F.

  Supp. 3d 1178, 1185 (D. Colo. 2018). Rejecting the predominant

  benefit test, the court recognized that the MWO provides a

  “completely relieved of all duties” standard. Id. We too do not

  discern ambiguity in the MWO, especially given that such a

  stringent standard is consistent with Colorado law. “Colorado

  provides more employee protection than does federal law, and the

  Department has published clear persuasive evidence of its intent to

  provide greater protections than those provided under the [FLSA].”

  Brunson, ¶ 5. As a result, we have no reason to consult other




                                    16
  interpretative aids, such as some federal courts’ view of allegedly

  analogous federal regulations.

¶ 35   Finally, the concerns raised by the Hospital do not convince us

  that applying the MWO’s plain language will lead to absurd results.

  Cf. City of Westminster v. Dogan Constr. Co., 930 P.2d 585, 590

  (Colo. 1997) (“Words and phrases should be given effect according

  to their plain and ordinary meaning, and ‘we must choose a

  construction that serves the purpose of the legislative scheme, and

  must not strain to give language other than its plain meaning,

  unless the result is absurd.’”) (citation omitted). The Hospital

  points out that the MWO applies only to private — not public —

  hospitals. See Colo. Minimum Wage Order No. 35, 7 Code Colo.

  Regs. 1103-1(2) (excluding government employers from definition of

  employer). So, the Hospital argues that adopting a strict

  completely-relieved-of-all-duties interpretation of the MWO would

  lead to the “discordant” and “absurd result of public hospital

  employees being paid less than private employees for performing

  exactly the same job, or public employees receiving an unpaid break

  and private employees being paid to work through their lunches.”




                                    17
¶ 36   Yet, the legislature has also chosen to distinguish between

  public and private employers when it comes to wages. See, e.g.,

  § 8-4-101(6), C.R.S. 2019. That is a quintessential policy choice.

  In fact, the Hospital recognizes that, in certain contexts, “a sound

  policy consideration may conceivably exist for differential

  treatment.” We leave to the legislature and the Division the policy

  decision whether the result posited by the Hospital here is likely,

  new, or desirable. Cf. Rare Air Ltd., LLC v. Prop. Tax Adm’r, 2019

  COA 134, ¶ 16 (“Judicial deference to an agency’s interpretation of

  a statute ‘is appropriate when the statute before the court is subject

  to different reasonable interpretations and the issue comes within

  the administrative agency’s special expertise.’” (quoting Huddleston

  v. Grand Cty. Bd. of Equalization, 913 P.2d 15, 17 (Colo. 1996))).

¶ 37   For the same reason, we decline to reject a plain language

  interpretation of the MWO on the ground that applying the federal

  predominant benefit test might be a good idea. The Hospital says

  that only this federal test “appropriately balances protecting

  employees with the operational realities of workplaces” and fits “the

  policy concerns and factual realities of the modern workplace —

  where thirty-minute meal periods are inherently limited, and


                                    18
  employees are almost always subject to potential work-related

  interruptions.” In response, the Division contends that the MWO’s

  plain terms incorporate the flexibility the Hospital desires by

  allowing an employer not to give an employee a duty-free meal

  break but only an on-duty meal period, for which the employee

  must be compensated. We do not wade into this debate. We simply

  apply the MWO’s plain language and leave to the policymakers the

  question whether the MWO appropriately accommodates “the

  modern workplace.”

                   2.    Witt’s Pre-2016 Meal Periods

¶ 38   Having decided that the Division did not err by applying the

  MWO’s plain language, we next consider whether the Division

  abused its discretion given the evidence presented. An agency

  abuses its discretion only if “no competent evidence in the record

  supports its ultimate decision.” Stor-N-Lock, ¶ 22. “‘No competent

  evidence’ means that the ultimate decision of the administrative

  body is so devoid of evidentiary support that it can only be

  explained as an arbitrary and capricious exercise of authority.”

  Ross v. Fire & Police Pension Ass’n, 713 P.2d 1304, 1309 (Colo.

  1986); Stor-N-Lock, ¶ 22.


                                    19
¶ 39   Put another way, we must sustain the agency’s decision if it is

  supported by substantial evidence in the record. Farny v. Bd. of

  Equalization, 985 P.2d 106, 109 (Colo. App. 1999). Substantial

  evidence is “the quantum of probative evidence that a fact finder

  would accept as adequate to support a conclusion, without regard

  to the existence of conflicting evidence.” Stiles v. Dep’t of Corr.,

  Denver Reception & Diagnostic Ctr., 2019 COA 10, ¶ 13 (citation

  omitted). “[W]e presume the validity and regularity of

  administrative proceedings and resolve all reasonable doubts as to

  the correctness of administrative rulings in favor of the agency.”

  Gessler, ¶ 11.

¶ 40   Considering the strict uninterrupted and completely-relieved-

  of-all-duties meaning of the MWO, the record supports the hearing

  officer’s conclusion that Witt’s pre-2016 meal periods were

  compensable. The hearing testimony showed that Witt was the only

  laboratory medical technologist on staff during her regular shift.

  During her meal periods, she was not permitted to leave the

  hospital and she was required to carry the lab phone and respond

  promptly to all lab calls, including requests for life-critical testing as

  well as non-critical calls.


                                     20
¶ 41   For example, Witt testified that couriers would come to the

  breakroom looking for blood specimens that had to be delivered to

  different hospital facilities, requiring her to leave her lunch and go

  back to the lab. Witt would answer phone calls from service

  representatives conducting follow-up calls about the performance of

  instruments. Nurses would stop by the lunchroom seeking Witt’s

  assistance with the supplies and operation of handheld equipment

  like glucometers and i-STATs. Also, because the lab shared

  supplies with the main hospital, Witt would have to respond to

  requests about inventory of items like reagent cartridges. Other

  times, ambulances would arrive with patients in life-threatening

  emergencies, requiring Witt to immediately respond to the trauma

  room. In short, “[w]hen you are the only laboratory person on duty

  in a building,” Witt said, “you are required to assist with everything

  that is needed regarding the laboratory.”

¶ 42   To the extent the Hospital suggests that it was improper for

  the hearing officer to consider evidence presented for the first time

  at the hearing, we disagree. As the Division notes, the applicable

  statute and regulation give the hearing officer wide discretion to




                                    21
  hear evidence, whether “new” or not. See § 8-4-111.5(2)-(3), C.R.S.

  2019; Dep’t of Labor & Emp’t Rule 6.5, 7 Code Colo. Regs. 1103-8.

¶ 43   The Hospital also contends that the hearing officer ignored

  evidence because the officer did not distinguish between the

  different types of uncompensated meal periods at issue, including

  (1) those involving “non-critical interruptions” and (2) those without

  interruptions. We are not persuaded because these distinctions

  were immaterial under a strict reading of the MWO. The former

  period must be compensated because the MWO requires an

  “uninterrupted” meal period,4 while the latter period was

  compensable because the MWO requires the employee to be

  completely relieved of all duties during the meal period and

  permitted to pursue personal activities, regardless of whether she is

  interrupted. Colo. Minimum Wage Order No. 35, 7 Code Colo. Regs.




  4 The Hospital argues that, under its written policy, Witt would have
  been compensated for these “non-critical” interruptions had she
  clocked in again. The policy, however, did not permit compensation
  for “de minimis” interruptions. In any event, the evidence also
  permitted a finding that her supervisors pressured her not to incur
  overtime pay and advised her not to clock in for minor interruptions
  but only to do so when she had to return to the lab to conduct
  testing.

                                    22
  1103-1(7). The evidence supported a finding that Witt had duties

  and restrictions during the meal periods.

¶ 44   Finally, we need not address whether the hearing officer

  correctly concluded that the meal periods were also compensable

  under the predominant benefit test. As explained, that test does

  not apply.

¶ 45   In sum, given its record support, we may not set aside the

  hearing officer’s determination that Witt’s pre-2016 meal periods

  were not uninterrupted and duty-free and, therefore, were

  compensable under the MWO. See Weld Air & Water v. Colo. Oil &

  Gas Conservation Comm’n, 2019 COA 86, ¶ 33 (“[W]e defer to an

  agency decision that involves ‘factual and evidentiary matters

  within an agency’s specialized or technical expertise’” — thus, “if

  conflicting inferences can be drawn from the record evidence, we

  will not second guess an agency’s choice between two opposing

  views.”) (citation omitted).

                      3.    Witt’s 2016 Meal Periods

¶ 46   Recall that, by December 30, 2015, and through her

  retirement in February 2016, the Hospital modified Witt’s meal

  period duties. After December 30, 2015, she no longer carried a


                                    23
  phone during her meal periods. Instead, a charge nurse carried the

  phone during that time. If an emergency arose, the nurse would

  interrupt Witt, who would clock back in and be paid. If a call was

  not urgent, the nurse would instruct the caller that Witt was not

  available until the meal period concluded. So, Witt remained

  subject to potential emergency interruptions and a geographic

  restriction, but no longer carried a phone or experienced

  non-critical interruptions.

¶ 47   Witt testified at the hearing that, after this change, the meal

  periods “became fair,” and she requested compensation only

  through December 30, 2015. She also acknowledged the Hospital

  had actually compensated her “all the way to February 11th, 2016.”

  So, she believed “they more than fairly compensated me for that.”

  The Hospital made these payments before receiving the Citation.

¶ 48   In the Citation, the compliance investigator ruled that Witt

  “was owed” compensation for meal periods through February 13,

  2016. Later, the hearing officer found that the Hospital “voluntarily

  chose to pay” Witt for meal periods after December 30, 2015, and

  that the compliance investigator “assumed the same facts and

  circumstances were applicable during the entire time frame at


                                    24
  issue” because the changed circumstances after December 2015

  were not adequately brought to the investigator’s attention. Then,

  even though evidence of these changed circumstances was

  presented to the hearing officer, she “ma[de] no finding” as to

  whether the meal periods after December 2015 were compensable.

  Yet, the hearing officer ultimately “affirmed” the Citation in full. In

  other words, even though the Hospital appealed all aspects of the

  Citation (including as to the 2016 meal periods) to the hearing

  officer, she did not make a finding as to the 2016 periods but let the

  Citation stand.

¶ 49   Likewise, the Division on appeal does not take a position on

  whether Witt’s meal periods in 2016, after the policy change, were

  compensable. In any event, the hearing officer affirmed the

  Citation’s ruling that those periods were compensable, while

  declining to explain why. So, as the Decision stands, the Hospital

  owed wages to Witt for the 2016 meal periods, even after the policy

  change. Although Witt has retired and the Hospital does not seek

  to recover money from her, the Hospital deserves to know, via an

  analysis accounting for the 2016 facts, whether those meal periods




                                     25
  were compensable under the MWO. This knowledge could impact

  the Hospital’s current and future policies on meal periods.

¶ 50   Because the Decision does not adequately consider whether

  Witt’s meal periods in 2016 were compensable, we set aside the

  Decision with respect to that timeframe only, and we remand with

  directions to return the case to the Division to consider this issue.

              4.    The Hospital’s Remaining Contentions

       a.    The Division’s Allegedly Inconsistent Interpretations
                                  of the MWO

¶ 51   The Hospital contends that the Division’s allegedly

  inconsistent interpretations of the MWO in this case render the

  Decision arbitrary and capricious. The Hospital distills three

  different versions of the Division’s interpretation of the MWO from

  the Citation, the Decision, and the Division’s answer brief in the

  district court. These various versions, the Hospital asserts, show

  the Division’s “fluctuating analysis” and confirms that “sufficient

  standards are lacking to guide [the Division’s] MWO enforcement.”

  According to the Hospital, the Division’s changing standards leave it

  and other similarly situated employers “in the dark.” That is,

  employers are deprived of fair notice of what standards or criteria



                                    26
  apply to the Division’s enforcement of the MWO. We are not

  convinced, however, that the Division’s view of the MWO has

  changed significantly throughout this case.

¶ 52   In the relatively concise Citation, the Division’s compliance

  investigator applied the MWO’s plain terms, without any suggestion

  that they lacked clarity. The investigator found that Witt was not

  paid for meal periods during which she was required to remain on

  call and could be interrupted to return to work at any time. The

  investigator decided that Witt “should have compensated for all ‘on-

  duty’ meal breaks, whether she was interrupted or not.”

¶ 53   In the Decision, the hearing officer addressed the Hospital’s

  argument — raised for the time before the hearing officer — that the

  predominant benefit test from federal law should be used when

  applying the MWO. As the Hospital points out, the hearing officer

  said, “Because of [the] material difference between the state and

  federal regulations, it is not clear whether the predominant benefit

  test is the appropriate standard for interpreting” the MWO.

  Doubting that this test should apply, the hearing officer stated that

  “the plain language of the [MWO] suggests that the more stringent

  ‘completely relieved from duty’ test should apply.” And, under the


                                   27
  more stringent test, the hearing officer found it “easy to conclud[e]”

  that Witt “was not completely relieved from duty and [the

  compliance investigator] made no error in determining [Witt’s] meals

  breaks were compensable.” Still, “in the interest of thoroughness,”

  the hearing officer also analyzed the facts under “the more lenient

  predominant benefit test” and concluded that Witt’s meal breaks

  were compensable under that standard.5

¶ 54   In the district court, the Division (like the hearing officer) took

  the position that, under the MWO’s plain language, Witt’s meal

  periods were compensable because she was “not completely relieved

  of all duties” and could not pursue personal activities during meal

  breaks that other employees could, such as running errands, going

  for a walk, or sitting outside. As the hearing officer had, the

  Division discussed the “significant and substantive difference”

  between the MWO and the federal regulation. The Division urged




  5The hearing officer emphasized, “I do not decide whether [the
  predominant benefit test] is the appropriate test to interpret [the
  MWO]. I examine the facts of this case using the predominant
  benefit test only to demonstrate that the hospital’s appeal fails even
  under the more lenient test.”

                                     28
  the district court to simply apply the plain terms of the MWO,

  without regard to the predominant benefit test.

¶ 55   The Division’s positions as this case has progressed do not

  reflect a sea change. We see no relevant difference between the

  Citation and the Division’s district court argument. Both relied on

  the MWO’s plain language, though the Division’s district court brief

  was more thorough. As the Hospital correctly observes, the hearing

  officer said she was not entirely sure whether the predominant

  benefit test should be used to apply the MWO. Even so, the hearing

  officer found that MWO’s plain language indicated otherwise, and

  the hearing officer concluded that Witt’s meal periods were

  compensable under the MWO’s plain terms. Then, the hearing

  officer analyzed the facts under the predominant benefit test merely

  to illustrate that the meal periods were also compensable under the

  Hospital’s preferred test.

¶ 56   At every step, the Division advised the Hospital that Witt’s

  meal periods at issue were compensable. There should be no doubt

  about the Division’s position. The Division has also made clear that

  it does not view the MWO as ambiguous and will apply its plain

  terms in a strict, literal manner. Given all this, we conclude that


                                    29
  the Division has not arbitrarily and capriciously enforced the MWO

  in this case.6

                   b.   Allegedly Improper Rulemaking

¶ 57   Next, the Hospital argues that the Division applied “an

  unwritten rule against an aggrieved party through adjudication.”

  By doing so, the Hospital concludes, the Division engaged in

  improper rulemaking in violation of the APA. We disagree.

¶ 58   “[T]here is not always a clear distinction between agency

  adjudication and agency rule-making.” Trans Shuttle, Inc. v. Pub.

  Utils. Comm’n, 89 P.3d 398, 407 (Colo. 2004). A “rule” is “the whole

  or any part of every agency statement of general applicability and

  future effect implementing, interpreting, or declaring law or policy

  or setting forth the procedure or practice requirements of any

  agency.” § 24-4-102(15), C.R.S. 2019. “‘Adjudication’ means the

  procedure used by an agency for the formulation, amendment, or




  6In a footnote in its opening brief, the Hospital criticizes the penalty
  assessed against it for not paying Witt’s claim in a timely manner.
  Because, in our view, this criticism is unsupported by any
  substantial argument, we decline to address it further. Taylor v.
  Taylor, 2016 COA 100, ¶ 13; see People v. Wallin, 167 P.3d 183,
  187 (Colo. App. 2007) (declining to address arguments presented in
  a perfunctory or conclusory manner).

                                    30
  repeal of an order and includes licensing.” § 24-4-102(2). Stated

  differently, an adjudication “involves a determination of rights,

  duties, or obligations of identifiable parties by applying existing

  legal standards to facts developed at a hearing conducted for the

  purpose of resolving the particular interests in question.” Trans

  Shuttle, 89 P.3d at 408 (citation omitted).

¶ 59   To determine whether a proceeding constitutes rulemaking or

  adjudication, “we look to the actual conduct and effect of the

  particular proceeding, as well as to the purposes for which the

  proceeding was brought.” Id. (citation omitted). The mere fact that

  the proceeding may have collateral prospective effects on other

  similarly situated parties does not convert an adjudication into

  rulemaking. Id.

¶ 60   In this case, the Division applied the literal language of the

  MWO, a duly promulgated and written rule. The Division

  determined that the Hospital had violated this rule with respect to

  Witt and the specific meal periods at issue. The Division’s ruling

  applied only to those prior violations and only to the Hospital and

  Witt. And the facts required to resolve the issues were particular to

  this proceeding. See id. While perhaps the Decision in this


                                    31
  proceeding may have effects on other similarly situated employers,

  the proceeding applied only to the Hospital, relying on facts specific

  to the Hospital’s operations. See id.

¶ 61   Still, the Hospital maintains that the Division “confirmed” that

  it was not applying a previously determined rule “by relying on

  different standards at every turn.” We have, however, rejected the

  Hospital’s argument that the Division applied different standards.

  Therefore, we conclude the Division engaged in adjudication, not

  rulemaking. See id.

                               IV.   Conclusion

¶ 62   The portion of the district court’s order affirming the Decision

  as to Witt’s 2016 meal periods is reversed, and the case is

  remanded with directions to return it to the Division for further

  proceedings consistent with this opinion. In all other respects, the

  court’s order is affirmed.

       JUDGE DAILEY and JUDGE MILLER concur.
