Last week, Senate Republicans introduced a bill called the National Right-to-Work Act, which would amend the National Labor Relations Act and the Railway Labor Act to prohibit union security agreements. Union security agreements are clauses in labor contracts that make union membership or payment of union dues a mandatory condition of employment. Federal law permits states to pass right to work laws, and 22 states currently have them on the books—mostly in the South or Western plains states. With Democratic control of the Senate and the White House, the recently introduced National Right-to-Work Act has little chance of becoming law. The bill also comes in the wake of failed legislation aimed at defunding the National Labor Relations Board for the remainder of 2011. The Democratically controlled Board has made several moves that have drawn the ire of employers and Republican lawmakers. The National Right-to-Work Act has been described as a political volley in response to the Board’s initiatives.
