Steven R. YELVERTON
v.
KEMP FURNITURE INDUSTRIES, INC., and Employment Security Commission of North Carolina.
No. 808SC419.
Court of Appeals of North Carolina.
March 17, 1981.
*554 Robert S. Cahoon, Greensboro, for claimant-appellee.
Johnson, Patterson, Dilthey & Clay by Ronald C. Dilthey, Raleigh, for respondent-appellant Kemp Furniture Industries, Incorporated.
V. Henry Gransee, Jr., Raleigh, for respondent-appellant Employment Security Commission of North Carolina.
WHICHARD, Judge.
The Commission made the following pertinent findings of fact:
2. The claimant worked on the employer's furniture assembly line in the print line department as a helper. The claimant worked from 4:45 p. m. until 6:15 a. m.
3. Approximately sixty feet away from the claimant's work station at the end of the furniture assembly line, Ricky Vick worked as the last man on the end of the line taking furniture off the line and then stacking the furniture.
4. Ricky Vick had worked in the print line department, but approximately two weeks prior to the claimant's last day of work had been transferred to the end of the assembly line. After Mr. Vick's transfer, the claimant began teasing Mr. Vick about being moved to the end of the furniture assembly line.
. . . . .
6. On the claimant's last day at work, the claimant approached Mr. Vick and stated that he was going to get Mr. Vick fired from his job and thereafter the claimant threatened Mr. Vick with bodily harm.
. . . . .
8. After the twelve o'clock break, the claimant, Mr. Vick, and [another employee] returned to their work stations. Shortly thereafter, the claimant stated to [the other employee] that he was going out and harass Mr. Vick some more. The *555 claimant left his work area and did not return.
9. The claimant proceeded to the tail end of the assembly line, and a co-worker heard the claimant and Mr. Vick arguing. The co-worker observed the claimant pick up a wooden post from a truck cart which was used to transport various materials. The claimant then put the wooden post on the truck cart and the co-worker "heard a lick," looked around and saw the claimant fall to the floor. Another co-worker observed Mr. Vick holding a wooden post and thereafter observed Mr. Vick strike the claimant on the head with the wooden post.
10. Mr. Vick and the claimant were discharged from their employment for violation of an employer policy which states that employees who are involved in fights and use or threaten to use any kind of weapon will be discharged.
These findings of fact are supported by competent evidence in the record. Therefore, they are conclusive on appeal. G.S. 96-4(m); G.S. 96-15(i); In re Thomas, 281 N.C. 598, 189 S.E.2d 245 (1972); In re Abernathy, 259 N.C. 190, 130 S.E.2d 292 (1963); In re Cantrell, 44 N.C.App. 718, 263 S.E.2d 1 (1980). The sole question presented by this appeal, then, is whether these findings of fact sustain the Commission's conclusion that claimant was disqualified from receiving unemployment compensation benefits by virtue of G.S. 96-14, which provides, in pertinent part, as follows:
An individual shall be disqualified for benefits:
. . . . .
(2) ... if it is determined by the Commission that such individual is, at the time such claim is filed, unemployed because he was discharged for misconduct connected with his work.
G.S. 96-14 (Supp.1979).
In determining whether facts found constitute "misconduct" within the intent of G.S. 96-14(2), this Court has quoted with approval the following definition:
* * * [T]he term "misconduct" [in connection with one's work] is limited to conduct evincing such wilful or wanton disregard of an employer's interest as is found in deliberate violations or disregard of standards of behavior which the employer has the right to expect of his employee, or in carelessness or negligence of such degree or recurrence as to manifest equal culpability, wrongful intent or evil design, or to show an intentional and substantial disregard of the employer's interests or of the employee's duties and obligations to his employer. * * *
In re Collingsworth, 17 N.C.App. 340, 343-344, 194 S.E.2d 210, 212-213 (1973), quoting Boynton Cab Co. v. Neubeck, 237 Wis. 249, 296 N.W. 636 (1941). This Court also has stated that "where the claimant is discharged because he willingly and knowingly violates a reasonable rule of his employer, the claimant is disqualified" from receiving benefits. Cantrell, 44 N.C.App. at 721, 263 S.E.2d at 3 (violation of employer's policy establishing rotation system for truck drivers by refusing to make trip constituted misconduct). See also In re Stutts, 245 N.C. 405, 95 S.E.2d 919 (1957) (willful violation of employer's rule prohibiting employees from changing the weights on their machines constituted misconduct); In re Collingsworth, 17 N.C.App. 340, 194 S.E.2d 210 (1973) (refusing to follow employer's rule requiring employees to wear ear protective devices constituted misconduct).
The Commission here found as a fact that the employer had adopted a policy "that employees who are involved in fights and use or threaten to use any kind of weapon will be discharged." It also found that "the claimant threatened [a fellow employee] with bodily harm" and that "a co-worker heard the claimant and [the fellow employee] arguing ... [and] observed the claimant pick up a wooden post ...." Finally, it found that claimant was discharged for violation of the employer's policy "which states that employees who are involved in fights and use or threaten to use any kind of weapon will be discharged." On the basis of these findings the Commission concluded that claimant was discharged for "misconduct connected with his work" within the *556 intent of G.S. 96-14(2). The Commission stated, in its Memorandum of Law, that "the claimant chose a course of action which was in complete disregard of the employer's best interest and represented a disregard of standards of behavior which the employer has a right to expect of his employee."
We note that the findings do not support a conclusion that claimant "willingly and knowingly violate[d] a reasonable rule of his employer," Cantrell, 44 N.C.App. at 721, 263 S.E.2d at 3, because the Commission failed to find that claimant had knowledge of the policy he was found to have violated.[1] The definition approved in Collingsworth, however, permitted the Commission to find misconduct and thus to deny benefits, not only for "deliberate violations or disregard of standards of behavior which the employer ha[d] the right to expect," but also for "carelessness or negligence of such degree or recurrence as to manifest equal culpability, wrongful intent or evil design, or to show an intentional and substantial disregard of the employer's interests or of the employee's duties and obligations to his employer." Collingsworth, 17 N.C.App. at 343-344, 194 S.E.2d at 212-213. The employer here had a substantial interest in the preservation of a peaceful atmosphere in the workplace; in having its employees perform their assigned tasks rather than harass their fellow employees; in not having its employees diverted from their assigned tasks by the harassment of fellow employees; and in not having its employees risk debilitating injuries at the hands of fellow employees. The claimant's actions in (1) threatening a fellow employee with bodily harm, (2) leaving his assigned work area for the avowed purpose of going to another work area to harass a fellow employee, and (3) picking up a wooden post in the course of an argument with the fellow employee, were sufficient to constitute "an intentional and substantial disregard of the employer's interests." They thus constituted "misconduct connected with his work" sufficient to disqualify him from receiving unemployment compensation benefits. We therefore reverse the judgment of the superior court and reinstate the decision of the Employment Security Commission which disqualifies claimant from receiving unemployment compensation benefits. See Cantrell, 44 N.C.App. at 723, 263 S.E.2d at 4.
Reversed.
CLARK and WEBB, JJ., concur.

Q. .... Mr. Yelverton, were you aware of a policy that if a weapon was used to threaten another employee that the employee doing the threatening would be discharged?
A. Yes.
