Last week several Detroit-area fast food restaurants were hit by a rolling demonstration by non-union fast food employees seeking higher wages. Certain McDonald’s, Wendy’s, Popeyes, Subway and Burger King retail stores reported employees calling in to take the day off and participate in demonstrations for an increase in fast food worker wages. By Saturday, an estimated 400 metro-Detroit workers participated in the walkout, part of the largest national demonstration by fast food workers in the U.S. to date.
