Nearly a year after signing record labor contracts with the United Auto Workers (UAW), two of the Big Three automakers find themselves dealing with the possibility of more strikes. The latest move by the UAW comes after the labor union said on Wednesday that members at Ford’s (F) tool and die unit at its Dearborn Rouge complex will go on strike on Sept.

The union, which won a major contract victory last year, has criticized the company for cutting jobs and delaying plans at an Illinois factory.

United Auto Workers union President Shawn Fain said Tuesday the union plans to hold strike authorization votes against Stellantis because the automaker is failing to live up to guarantees it made in the 2023 labor deal it reached with the union at the conclusion of a six-week strike.
