Right to Work advocates around the country got another win yesterday when the 7th US Circuit Court of Appeal in Chicago upheld the Wisconsin right to work law. The ruling came in a challenge to the law brought by two local affiliates of the International Union of Operating Engineers (IUOE) against the Wisconsin law. The law was upheld last fall in a decision rendered by the US District Court, but the unions appealed that decision to the 7th circuit. While union leaders are debating their next move, Wisconsin remains one of 28 states across the country that have adopted right to work, which prohibits unions the mandated payment of monies to unions by non-union workers. Missouri was the most recent state to pass right to work, when it became effective back in February.
