The union told 5,000 workers to step down at the plant, General Motors’ largest in the United States, as it escalates its labor action at the three large U.S. automakers.
The United Automobile Workers union called on 6,800 workers to walk off the job at a large factory that makes one of Stellantis’s most profitable vehicles.
The three U.S. automakers say they are already at a disadvantage to nonunion rivals while labor leaders hope that big gains in negotiations will inspire workers in Southern states to unionize.
