Three Metro employes were found guilty of contempt of court yesterday for their activities during Metro's seven-day transit strike that ended last week.

Two of the employes, Gary Young and Michael Golash, were ordered to pay $100 in damages to Metro and given one week to pay. The third, Eugene Ray, was ordered to pay $300 to Metro.

The damage awards were made on findings of civil contempt of court. Federal District Judge Thomas Flanery also warned clearly that any repetition of the strike could result in his assessing criminal contemtp penalties - which include heavier fines and the possibility of jail - against defendants.

Young and Golash both told reporters after the hearing that they are members of the Progressive Labor Party, an independent communist organization. George Davis, president of Local 689 of the Amalgamated Transit Union, had complained to reporters that during the strike that "communists" regularly disrupted his union meetings. The union dsavowed responsibility for the strike.

Beyond admitting his affiliation, Golash declined to talk with reporters. He was accused by Metro of waving his right arm and hollering "Strike, Strike, Strike" during a meeting of Metro employes at RFK Stadium on July 23, during the middle of the strike. A tape of a television news broadcast and Golash's own testimony confirmed that concurrence.

Golash is a bus driver assigned to the Northern Division.

Young, a track repair mechanic with the subway at Brentwood yard, was accused by Metro of picketing after receiving the temporary restraining order. Young told reporters afterward that he had worked in the coalfields in the past and that "intervention by the government on the side of the bosses doesn't surprise me."

"It's time for the workers to consider putting revolution and socialism on the agenda," he said. He has returned to work for Metro, he said, "because I have a need to survive."

The third person convicted of contempt yesterday was Eugene Ray, a bus driver from the Four Mile Run Division. Radio and television tapes from two different days show that Ray encouraged his fellow workers to continue striking, Flannery assessed heavier damages against Ray.

All three are subject to Metro discipline, including possible suspension or firing.

Metro has fired four employes as a result of its post-strike investigation, has suspended 56 for periods of from one to five days and has handed out 12 reprimands. Fifty strikers have been exonerated and 122 of 266 cases have been completed, according to Metro spokesman Marilyn Dicus.
