Volkswagen AG (VOWG_p.DE) skilled trades workers at the company’s lone U.S. auto assembly plant will vote on Dec. 3 and Dec. 4 whether to be represented by the United Auto Workers, the union said on Wednesday. Volkswagen, which had earlier been the most supportive of the UAW among foreign automakers with U.S. plants, fought the petition by the UAW for a vote of 165 skilled trades workers at the plant in Chattanooga, Tennessee.
