UAW, GM reach tentative contract deal after talks hit weekend snag

General Motors and the UAW reached a tentative contract agreement Oct. 30 more than six weeks after the union began its strike against the Detroit 3 and two days after the union expanded the walkout to a fourth GM assembly plant.

A source familiar with the talks confirmed the agreement to Automotive News. Several news outlets also reported the development. There was no immediate comment from the UAW. GM declined to comment.

GM was the last of the three automakers to agree to terms with the union, which stopped picketing Ford Motor Co. late on Oct. 25 and Stellantis on Oct. 28.

The deal is subject to ratification by GM's 46,000 UAW members.

In a surprise move, the UAW on Oct. 28 added Local 1853, which represents workers at GM’s manufacturing complex in Spring Hill, Tenn., to the strike.

GM builds the electric Cadillac Lyriq crossover, the GMC Acadia and the Cadillac XT5 and XT6 in Spring Hill. That followed an earlier strike expansion on Tuesday to include 5,000 GM workers who build highly profitable full-size SUVs in Arlington, Texas.

In addition to the GM workers on strike, nearly 2,500 employees at other GM plants were temporarily laid off as a result of the work stoppages, which have cost the company more than $800 million.

Ford's tentative agreement with the UAW, if ratified by that company's 57,000 members, will give raises totaling 25 percent over the next four years, reinstate cost-of-living adjustments and give top wages to new hires after three years, among other benefits. Stellantis matched the 25 percent wage raise and also agreed to reopen the idled Belvidere Assembly in Illinois.

GM and union negotiators had met for several days in an effort to reach a deal, including on Saturday, and the automaker had agreed to a 25 percent wage hike, according to sources familiar with talks.
