Union vote underway at Volkswagen's only US plant

Workers at Volkswagen's lone U.S. factory are voting this week on whether to join the United Auto Workers in what is the union's third attempt at organizing the plant.

Voting began Wednesday for the 4,100 hourly employees at Volkswagen's factory in Chattanooga, Tennessee, and will extend through Friday.

This is the third time in 10 years the UAW has sought to represent VW Chattanooga workers, and winning a vote to organize the VW plant would be a significant milestone for the union.
