DETROIT — The United Auto Workers union and General Motors have reached a tentative agreement on a new contract.

The agreement avoids a strike for now. The UAW had set a deadline of 11:59 p.m. EDT Sunday to reach a new agreement or go on strike.

Details of the proposed contract weren’t immediately available.

The UAW said local union leaders will meet in Detroit Wednesday to vote on the agreement. If they approve it, workers at GM’s U.S. plants will then vote on it.

The proposed contract with GM covers nearly 53,000 U.S. auto workers.

Workers at Fiat Chrysler approved a new contract agreement last week. The union hasn’t yet reached an agreement with Ford.
