Striking members of the United Steelworkers of America, Local 8319, have been served with a temporary restraining order in an attempt to halt the violence directed at supervisory personnel of Amax Magnesium Corp. who are keeping a magnesium plant on the west side of the Great Salt Lake open.

Members of the Tooele County Sheriff's Office served papers on union officials Monday evening in an attempt to halt the tire slashing, rock-throwing and other damage that has occurred since 225 workers went on strike Saturday at 6 p.m.Jerrald Conder, an attorney for Amax, said 3rd District Judge J. Dennis Frederick signed the temporary restraining order and papers were served on Don R. Bryant, president, and union officers Leon McKenzie, Brad Clark, Dave Hog-gan, Clark Ward, Wes Chivers and Jerry Nash.

They and members of their union are enjoined from unlawfully obstructing traffic on the road leading to the Rowley plant 14 miles north of I-80 on the west side of the lake.

The order said no more than two people can picket at the Amax office at 238 N. 22nd West and the picketing is limited between 7 a.m. to 8 p.m. No more than six picketers are allowed at the plant site between 7 a.m. and 8 p.m., and the same hours apply to no more than two picketers at the Tooele County Courthouse parking lot.

The order prohibits the picketers from using alcoholic beverages on the picket lines and from committing violent acts.

Since the restraining order was issued, Conder said, there have been reports the order was breached with the slashing of tires on a bus kept at the county courthouse to transport supervisory personnel to and from the plant. In addition to numerous rock-throwing incidents, Conder said, the air hoses and tires were slashed on a vehicle attempting to make a delivery at the plant.

A three-year contract with the union expired March 19, but the employees worked without a contract pending negotiations on a new contract. Union officials saw they were going to give up some wages and benefits under the new contract and the workers voted for a strike. rather than give up something. Company officials feel the proposed contract is the best United Steelworkers contract in Utah.

Union officials disagreed and re-fuse to make more concessions. No negotiations are planned.
