An anti-union group is going after the UAW over the auto worker's neutrality agreement arrangements with some auto parts suppliers. The UAW is using those agreements for the companies to stay out of union organizing drives with some success. An anti-union group charges that the UAW and the auto manufacturers are teaming up to unduly pressure auto parts suppliers to go union in violation of federal labor law. The National Right To Work Legal Defense Foundation has support from corporate backers, including Walmart's Walton family. It's alleging that in several cases the UAW and auto parts suppliers reached agreements to unionize before a majority of workers signed union cards. These neutrality agreements are proving to be effective union organizing tools and if the agreements can be ruled illegal it would be another blow to union organizing. The Republican controlled National Labor Relations Board will decide the issue.
