On Tuesday, Missouri voters rejected a right-to-work law that eliminated mandatory fair share fees in the private sector. In a public referendum, about two thirds of voters voted “no” on Proposition A, which supported the right-to-work law. Unions and other opponents of Proposition A outspent right-to-work supporters by over three times in their effort to defeat the law, according to the AP.

This June, the United States Supreme Court held in Janus v. AFSCME, Council 31 that the collection of mandatory fair share fees from public-sector workers is unconstitutional.
