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 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.
The strike at the truck manufacturer by 4,000 members of the United Automobile Workers comes in the middle of the union’s strikes at three large U.S. car companies.
