The United Auto Workers has filed unfair labor practice charges against Honda Motor Co. in Indiana, Hyundai Motor Co. in Alabama, and Volkswagen AG in Tennessee for alleged illegal union-busting activities amid organizing drives. The United Auto Workers (UAW) accuses Honda in Indiana of implementing harsher production standards and using work assessments to retaliate against employees trying to unionize. They also allege that Hyundai managers in Alabama destroyed pro-union materials, and VW in Tennessee threatened employees and restricted the distribution of union materials to prevent unionizing efforts. The companies deny the allegations and say they respect workers' right to choose union representation.
