UAW, General Motors reach tentative deal to end six-week strike

General Motors has reached a tentative agreement with the United Auto Workers (UAW), becoming the last of the three major U.S. automakers to strike a deal and potentially marking the end of the union's six-week strike.

The other two members of the Big Three automakers, Ford and Stellantis, reached agreements with the union in recent days. Like its counterparts, General Motors agreed to a 25-percent general pay increase over the course of a four-year contract.

The UAW had expanded its strike against the final holdout Saturday evening, after reaching a deal with Stellantis. Some 4,000 workers walked out at a General Motors engine plant in Spring Hill, Tenn., joining the 14,000 others already on strike.

The tentative agreement with General Motors could spell the end of the UAW strike, which started more than six weeks ago, when the Big Three failed to reach an agreement with the union before its previous contract expired Sept. 14.

The union initially called on workers to walk out at only a handful of plants, before ramping up pressure on the automakers with additional strikes.
