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 has filed charges of unfair labor practice and grievances against the Jeep maker, citing abandoned commitments made in 2023.

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