On Monday, the United Auto Workers (UAW) union filed charges against Volkswagen claiming that the company is refusing to collectively bargain with some of the workers at its Chattanooga, Tennessee plant. Several weeks ago, over 70% of the facility's skilled workers voted to unionize with the UAW. This vote marks the only foreign-owned automobile plant located in the southern United States to unionize.
