National Labor Relations Board attorneys have advised the board to dismiss unfair labor practice complaints from eight workers at Volkswagen plant in Chattanooga, Tenn., against the United Auto Workers. The attorneys also called for the labor law enforcement agency to dismiss related charges against the car maker.

The news is a big win for UAW, which has been struggling to organize the plant’s workers and make inroads into southern “right to work” states. It has benefitted from aid from the company’s German union, IG Metall, which due to European labor law has considerable influence over company decisions.
