Automakers Stellantis and General Motors (GM) have individually reached tentative contract agreements with the United Auto Workers union, ending strike action against the automakers in the US.

Following roughly six weeks of targeted striking, the UAW was able to reach a tentative deal with Stellantis on 28 October and GM on 30 October. Both deals include 25% in base wage increases through April 2028, with the respective agreements covering UAW members working at Stellantis and GM facilities across the US.

Among other things, the UAW bargained to eliminate wage tiers, reinstate cost-of-living allowances (COLA) and retain the right to strike over plant closures. In its deal with Stellantis, the UAW also won the reinstatement of the Belvidere Assembly Plant in Illinois, which was idled by the automaker eight months ago.

In addition to that plant coming back, Kallanish learns Stellantis has agreed to add more than 1,000 jobs at a new battery plant in Belvidere.

“We look forward to welcoming our 43,000 employees back to work and resuming operations to serve our customers and execute our Dare Forward 2030 strategic plan to maintain Stellantis’ position at the forefront of innovation,” Mark Stewart, Stellantis North America’s chief operating officer, says in a statement.

GM has agreed to place Ultium Cells and GM Subsystems under the UAW’s Master Agreement. Ultium Cells, a joint venture between GM and LG Energy Solution, has an existing battery plant in Ohio and two forthcoming plants expected in Tennessee and Michigan.

In a statement, GM ceo Mary Barra says the company is “pleased to have reached a tentative agreement with the UAW that reflects the contributions of the team while enabling us to continue to invest in our future and provide good jobs in the US.”

These developments come days after the UAW reached a tentative agreement with Ford, the first of the Detroit Three to strike a deal. While each agreement goes through its respective ratification process, Stellantis and General Motors workers are expected to return to their positions.

Meanwhile, Unifor – which represents autoworkers in Canada – was able to reach a deal with Stellantis on 30 October just hours after commencing a strike against all of its Canadian facilities. The agreement will cover 8,200 Unifor members and is still subject to union ratification.

Among other things, the agreement includes two additional paid holidays, along with pension plan improvements and the reactivation of COLA in December 2024. General wage increases were also won, sitting at 10% in year one, 2% in year two and 3% in year three.

“The agreement puts in place all the elements of our pattern agreement, the protections autoworkers need throughout the EV transition, and next-generation products our members will build for years to come,” Unifor Stellantis master bargaining chair James Stewart said in a statement.

Unifor’s deal with Stellantis followed the pattern agreement it previously reached with Ford and GM.
