On Tuesday, Missouri voters sent a message to the Republican-controlled state Legislature: The state must protect unions. It is the first state since 2012 to overturn a right-to-work law that aimed to weaken unions by severely restricting their cash flow.Tuesday’s vote in Missouri serves as the first test of the right-to-work movement’s momentum since a crucial Supreme Court decision in June dealt a blow to unions nationally. In Janus v. American Federation of State, County, and Municipal Employees, Council 31, the court ruled that public-sector unions could no longer require fees for representation from non-union members, overturning years of precedent and effectively making right-to-work the standard in public-sector unions.
