The UAW achieved a breakthrough victory in organizing VW workers in Tennessee, winning 73% of the vote. It was the union's first win at a foreign automaker's plant in the South. The UAW targets Mercedes plants in Alabama, with an election starting May 13th. Mercedes is expected to mount a tougher anti-union campaign than VW did. Analysts say the UAW must quickly negotiate a good contract to maintain momentum. Other unions are looking to the UAW's success to help organize in the anti-union South. Biden praised the UAW and recent union wins for expanding the middle class, while southern governors warned unions would jeopardize jobs.
