On Monday, Volkswagen announced that it would be taking the case involving unionization among its workers in Tennessee to the U.S. federal appeals court. The case is over whether the United Auto Workers union (UAW) will represent some of the company's employees at this plant. The UAW filed unfair labor practice charges against the company after Volkswagen refused to bargain with 160 workers who voted to unionize with the UAW in December. This past month, the NLRB voted to uphold the UAW's election.
