Working people in Missouri this week notched the latest win for the American labor movement, which has been under attack in recent months by President Trump and the U.S. Supreme Court. Workers in the “Show Me” state resoundingly voted down “Right to Work,” in a state where just 8.7 percent of workers were union members last year. The vote “shows how out of touch those institutions are,” said A.F.L.-C.I.O president Richard Trumka. “How out of touch the Republican legislature in Missouri is, how out of touch the Supreme Court is.” The victory in Missouri is the latest sign of a resurgence in the labor movement. Polls show rising popular support for unions and an increase in membership in teachers’ unions after walkouts in several states during the past school year. “I think this will build momentum and send a message to all legislators,” Trumka said, “that if you vote against the people, go against the will of the vast majority of working Americans, it’s going to cost you.”
