This is an appeal by Dorothy J. Van Horn, claimant, from an order of the Employment Appeals Board which approved and upheld a referee’s finding, after hearing, that claimant was disqualified for receiving unemployment compensation under ORS 657.176(2)(a)1 because she was discharged for wilful misconduct in connection with her work as a television technician.
Claimant claims that her discharge was directly related to the fact that she had filed a complaint under federal law against the employer for sex discrimination against and harassment of her in connection with her work. The employer asserts that claimant was discharged because she became unjustifiably upset and walked off the job when she was reassigned from a live camera broadcasting the principal television news program of the day on October 2,1975 to a camera which was used to broadcast still shots used during the program. Both jobs pay the same and are rated even, but claimant claims that the still camera is a less responsible job.
Claimant testified in support of her claim that although she left her camera for most of the show she had permission to do so from her supervisor. She also produced testimony from two other station employes that what she did was not uncommon for the still-camera technician. These employes also testified to circumstances that could lead to the inference that *66claimant was being harassed by supervisors. In this regard, the further fact must be weighed, however, that the technician who replaced claimant on the live camera was a woman.
The station produced substantial evidence which contradicted claimant’s principal evidence. This was to the effect that the claimant did not have permission to leave her camera for the rest of the program after she had arranged her still shots, that in fact it developed that she was needed during the program and could not be found although efforts were made to find her, and that her discharge the following day was because unexcused abandonment of camera assignment during a live broadcast of the station’s top program was impermissible, and it was not related to her discrimination complaints. The employer’s evidence was also that leaving vital duties during a live broadcast is not condoned by practice in that station; that on one occasion about two years earlier a male employe who left his job of transmitter operator during such a program to go to the vehicle parking lot had been discharged.2
There was a plethora of reliable — substantial— evidence to support the referee’s and the Employment Appeals Board’s de novo decision. ORS 183.482(7) and (8)(d); Cantrell v. Employment Division, 24 Or App 215, 545 P2d 143, Sup Ct review denied (1976). We find no error of law in the record.
Affirmed.
