Akron, Ohio ? With 12 of the 14 Steelworkers union locals at Goodyear Tire & Rubber Co. approving a proposed three-year contract and only one rejecting it, the pact appeared headed for ratification.

Union officials reported that most of the locals favored the tentative contract by wide margins.

Ratification requires approval of at least eight of the unions’ Goodyear locals and an overall majority.

Members of the United Steelworkers of America Local 878, in Union City, Tenn., rejected the contract by a narrow 2 percent margin, said Ricky Waggoner, local treasurer. The local has about 3,300 members, but Waggoner declined to say how many voted.

At Steelworkers Local 307 in Topeka, members on Tuesday approved the contract by a 75 percent margin, according to Robert Tripp, local vice president. He wouldn’t disclose how many of the local’s 1,500 members voted.

Wayne Ranick, a spokesman for the union in Cincinnati, said the last plant would vote Friday in Danville, Va., and the final results would be announced Monday.

Union officials have said the contract would give the Steelworkers a seat on Goodyear’s board of directors. Negotiations centered on giving the nation’s biggest tire company financial flexibility in return for job security.
