The evidence establishes that claimant, a nurse's aide, had previously been told that she needed to be more careful in speaking to patients. The incident that culminated in her termination was her use of foul language toward a particular patient. Although claimant denied the use of such language, that merely presented a question of credibility which was within the exclusive province of the Unemployment Insurance Appeal Board to resolve (see, Matter of Padilla [Sephardic Home for the Aged — Roberts], 113 A.D.2d 997). The record also reveals that claimant had been furnished with the employer's policy precluding the use of such language. The policy further provided that any disruption in patient care could result in an employee's discharge. Under the circumstances, there is substantial evidence in the record to support the decision disqualifying claimant from receiving unemployment insurance benefits due to misconduct (see, Matter of Valentin [American Museum of Natural History — Roberts], 103 A.D.2d 919).
Decision affirmed, without costs. Mahoney, P.J., Casey, Weiss, Yesawich, Jr., and Harvey, JJ., concur.
