At the end of 2015, skilled workers employed at a Volkswagen plan in Tennessee voted to unionize with the UAW. Despite these workers' decision to unionize, the 1,500 hourly employees at the plant voted against unionization. As a result, the employer has refused to bargain with the workers who are now represented by the UAW. Labor leaders from the union will meet later this month with the company's upper level management in Germany in an effort to resolve this dispute. So far, a complaint has been issued by the NLRB over VW's refusal to negotiate.
