UAW workers at Stellantis' Sterling Heights Assembly Plant in Michigan went on strike Monday in an effort to pressure the company to make a better labor contract offer. The plant produces the highly profitable RAM 1500 series pickup truck, and UAW President Shawn Fain said the strike is an attempt to “stand up for the rights of our members and their families.” The strike is part of the UAW's concurrent strikes against the “Big Three” automakers, and Stellantis did not immediately respond to a request for comment.
