IN THE MATTER OF BARCENE

It is well settled that a knowing violation of an employer's established policies can constitute disqualifying misconduct (see Matter of Graham [Commissioner of Labor], 305 A.D.2d 922). In the instant matter, substantial evidence supports the decision of the Unemployment Insurance Appeal Board that claimant accessed nonwork-related Web sites, including dating services and pornographic Web sites, and that he was aware that the employer's policy explicitly prohibited such use of office computers. Claimant's assertion that he did not engage in such conduct presented a credibility issue for the Board to resolve ( see Matter of Bach [Commissioner of Labor], 306 A.D.2d 736).

Mercure, J.P., Crew III, Mugglin, Rose and Kane, JJ., concur.

ORDERED that the decision is affirmed, without costs.
