Following the filing of unfair labor practice complaints by workers at the Webasto-Detroit auto parts plant, the United Auto Workers (UAW) announced Friday that a delegation will bring their concerns about “illegal anti-union behavior” directly to officials with the German parts supplier at a meeting set for next week, and may seek litigation if the issues are not addressed.
