In both houses in Michigan they passed bills that make Michigan the 24th right to work state.
The vote passed with a six point margin in both houses.
Unions are planning major protests this week against the legislation.
Union members and others opposed to Michigan becoming a “right-to-work” state plan major protests in the state capital this week to try to stop Republicans from restricting labor unions in the cradle of the unionized U.S. auto industry.
Right-to-work opponents will begin to converge on Lansing on Monday, organizers said, and they expect thousands at the rally on Tuesday when the state legislature reconvenes.
With Republicans in control of the legislature and the governor committed to sign the laws, Michigan could become the 24th right-to-work state by the middle of the week, dealing a stunning blow to the power of organized labor in the United States.
Michigan Republicans surprised labor unions on Thursday by pushing through the legislature in a day a proposal making union membership and dues voluntary in the private sector. The state Senate also voted to apply that to the public sector, except for police and fire unions.
“Never in a million years did I think that Michigan would ever become a right-to-work state. We are Motown, The Motor City. Michigan was built on unions,” said Libby Brown, president of a teachers’ union local in Jackson, Michigan, referring to the state’s roots in popular music and auto manufacturing.
