The UAW’s years-long effort to organize auto workers at the Volkswagen of America plant in Chattanooga, TN, takes a major step forward. The union claims more than 50% of the complex’s 4,000 hourly workers have signed cards indicating they want UAW representation. Upon reaching 70%, the union says it will either seek recognition from VW as the workers’ bargaining agent or seek an election supervised by the National Labor Relations Board.
