Plaintiff-employer appeals a decision of the Board of Review awarding unemployment benefits to Karen A. Bontems.
Plaintiff operates several Burger King restaurants in Utah and is owned by John Gullo. Bontems had worked for plaintiff for nearly four years when, in March 1985, Gullo discharged her as manager of the Logan Burger King. By letter to Bontems, Gullo specified several reasons for the discharge, most of which concerned Bontems’ alleged temper tantrums and use of abusive language.
Bontems had risen to the level of manager in two different restaurants operated by plaintiff. During 1984, Bontems managed the Logan restaurant, which had one of the better sales records and the highest profits of the restaurants owned by plaintiff in northern Utah. Gullo considered Bontems to be a very good technical manager, although he was concerned throughout her employment with her temperament and attitude toward supervision. Because of these problems, he considered placing Bon-tems in an assistant manager position in the Ogden area for additional training.
A series of confrontations occurred between Bontems, area supervisors, and Gul-lo during February and March 1985, which resulted in Bontems being placed on paid vacation for one week so that Gullo could “review her situation” and so that she could reflect upon why sales were below expectations and why she wanted to keep her job. While on vacation, Bontems entered the Logan restaurant to pick up some personal property. Gullo considered this a *471violation of his directive to be on vacation and issued the letter of termination.
A representative of the Department of Employment Security denied Bontems’ application for unemployment benefits on the ground that she was discharged for just cause or for an act or omission in connection with employment which was deliberate, willful, or wanton and adverse to the employer’s rightful interests. U.C.A., 1953, § 35-4-5(b)(l) (Repl.Vol. 4B, 1974 ed., Supp.1986). Bontems appealed, and a hearing was held before an administrative law judge. Based upon evidence adduced at the hearing, the administrative law judge reversed the decision of the Department representative and allowed benefits on the ground that the conduct for which Bontems was discharged was not disqualifying under the aforementioned statute. That decision was thereafter affirmed by the Board of Review.
The Board made the factual determination that Bontems’ misconduct was hot within her power and capacity to control or prevent.1 The Board’s decision specifically states:
The Board of Review finds that the claimant did not have the emotional and/or personality talents and ability to perform the duties of the job to which she was assigned. Upon consideration of all the evidence in the record, it is concluded that the claimant did not have the skills and capability of dealing with the employer’s other personnel in the place of business and in handling the customer relations requirements called for in the particular position to which the claimant was assigned.
Plaintiff contends that the conclusion reached by the Board of Review is unreasonable and irrational in view of the record and that Bontems' display of temper, physical and verbal abuse of employees, and failure to stay away from the restaurant during vacation constituted intolerable conduct justifying termination.
The standard of review in this unemployment insurance case is that set forth in U.C.A., 1953, § 35 — 4—10(i) (Repl.Vol. 4B, 1974 ed., Supp.1985) (amended 1986), which provides in pertinent part: “In any judicial proceeding under this section the findings of the Commission and the Board of Review as to the facts if supported by evidence, shall be - conclusive and thp jurisdiction of said Court shall be confined to questions of law.”
This Court has consistently held that the Commission’s findings of fact are conclusive and binding, and are to be sustained if supported by competent and substantial evidence in the record.2
In the case of Salt Lake City Corp. v. Department of Employment Security,3 the Court observed: “In reviewing the Commission’s findings of fact, this Court is limited to determining whether those findings are supported by substantial evidence.... For this Court to set aside findings of fact, they must be without substantial support in the record and hence clearly arbitrary and capricious.” 4 The Court additionally noted that the evidence in support of the Commission’s findings of fact need not be undis*472puted: “[Substantial evidence need not be uncontradicted evidence. It is for the administrative agency, not this Court, to choose between conflicting facts. It is beyond our prerogative to determine that the Board of Review’s reliance on [claimant’s] testimony was inappropriate.”5
In the instant case, the evidence of the circumstances leading up to Bontems’ discharge is in substantial conflict. This is particularly true with respect to the magnitude of Bontems’ alleged misconduct and whether Gullo in fact forbade her from going upon the premises under any circumstances during her vacation.
The Board of Review obviously found Bontems’ testimony to be the most persuasive. However, it also appears that considerable reliance was placed upon Gul-lo’s testimony.
At the hearing before the administrative law judge, Gullo testified: “At no time did I ever really think that [Bontems’] actions were malicious.... I just thought it was a case of hypertension or whatever it was, but she had occasions of flare-ups.” Later, Gullo stated: “I really didn’t think her actions were willful or intentful [sic].... ”
Plaintiff urges that the Board took the foregoing statement of Gullo’s out of context. However, a review of the record reveals that such was not the case. The record shows that during Bontems’ term of employment Gullo considered her to be a good manager and believed that her temperament and other shortcomings could be overcome, the bottom line being that she was a valuable employee worth saving. It appears that Bontems’ discharge was more directly triggered by Gullo’s dissatisfaction with the failure of the Logan restaurant to achieve its profit potential. This is clearly evidenced by Gullo’s testimony which follows:
Gullo: Uh, there was — there was continuing Karen, although was a very good technical manager, had certain personality problems and people problems. She had been counseled about this continuously, really probably through her whole term of employment. ...

Gullo: Okay. Anyways, it did happen. I’m not really clear of the time. At the same token I’d like to submit this as evidence which is a document from 1983 talking about Karen’s situation in regards to the complaint letter to her just to establish the fact that although she was a good technical manager and basically performed, we have always had problems with her that we felt we could work out relevant to her temperament and her attitudes towards customers and employees.

Gullo: ... And although we were doing a good job, it was very evident that, based on this market track, that we had a lot of potential that we weren’t tapping.
I explained to Karen my feelings for her which were — were positive comments. On the other hand, I explained to her that based on the things that were happening, her general dictatorial attitude with her hourly employees, and other — her lack of supervision, etc., etc., I said I really needed some time to review her situation because I could no longer tolerate or bear with the potential negative impact of what was happening in the restaurant.

Gullo: ... Alicia Narby ... and I sat down with her and I explained the situation to her and I asked her if she would contemplate taking Karen on as an assistant manager to — and work with her until the next restaurant opens up because then I would do some jockeying, basically saying, “Hey, if we can salvage her because of the money we’ve got invested in her, we should try and salvage her.”
At no time did I ever really think that Karen’s actions were malicious at that time. I just thought it was a case of *473hypertension or whatever it was, but she had occasions of flare-ups_

Gullo: ... Based on the fact that she was a decent mechanical manager, I really didn’t think her actions were willful or intentful, I did this as a gesture of faith of her....

Gullo: ... I’ve told Karen, yes, she did a good job; but it’s evident that she wasn’t maximizing the restaurant. It could have been better....

Gullo: So, therefore, all these things that she talks about in regards to the profits, yes, it was there. I did state she was a good mechanical manager. What we are talking about here is a separate issue which is how she handled her employees and how she handled my customers.
The record is clear that Bontems managed the Logan restaurant very profitably in 1984. This is so, notwithstanding Gullo’s testimony that Bontems’ language and attitude had always been a problem throughout her employment experience. It was thus not unreasonable for the Board to reject Gullo’s assertion that those very acts of misconduct that occurred in 1984 suddenly caused a failure to reach new projected sales levels in 1985.
There being substantial evidence in the record to support the factual determination of the Board, we affirm its decision.
STEWART and DURHAM, JJ., concur..An employee is not disqualified from receiving unemployment benefits when his or her discharge is due to inefficiency, unsatisfactory conduct, or failure of good performance as a result of inadvertence or isolated errors in judgment or discretion. Lane v. Board of Review of Indus. Comm'n, 727 P.2d 206 (Utah 1986) (citing Continental Oil Co. v. Board of Review of Indus.Comm'n, 568 P.2d 727, 730 (Utah 1977)); see also Clearfield City v. Department of Employment Sec., 663 P.2d 440, 444 n. 2 (Utah 1983). Instead, the degree of culpability which will disqualify an employee from receiving benefits under section 35 — 4—5(b)(1) involves "volitional acts by an employee who could not have been heedless of their consequences.” Clearfiéld City, 663 P.2d at 444. Implicit in this standard is the necessity of control by the employee. See Lane, 727 P.2d 206.
