Oklahoma set to repeal collective bargaining law 19 Apr 2011 The Republican-controlled Oklahoma Senate dealt organized labor another defeat on Tuesday when it voted to repeal a collective bargaining law. The 29-19 vote means that some of the state's fastest-growing cities no longer will be required to collectively bargain with sanitation workers and other non-uniformed workers. The measure already passed the Oklahoma House and now goes to Governor Mary Fallin, a Republican, who is expected to sign it into law.
