Earlier this month, a federal appeals court upheld Wisconsin’s 2015 Right-To-Work law. A similar battle is playing out in Kentucky, where Governor Matt Bevin has asked a judge to dismiss a suit filed by the Kentucky State AFL-CIO and Teamsters Local 89 against Kentucky’s recently enacted law.

In Michigan, the UAW and Harsco Rail ran afoul of that state’s right to work law when they illegally reduced a welder’s wages after he opted out of the union. According to the contract in place, the journeyman welder was entitled to an  $0.75 premium, but when he opted out of union membership, the UAW revoked his journeyman card in retaliation and instructed the employer to pay him accordingly.
