LANSING, Mich., Dec 11 (Reuters) - The Michigan House of Representatives on Tuesday gave final approval to a "right-to-work" law covering public sector workers such as teachers, which would make union membership and payment of dues voluntary.
The Republican-majority House passed the law by a vote of 58 to 51. The only government workers excluded would be police and fire unions.
A second bill applying "right-to-work" to the private sector in the state that is home to the large U.S. auto industry, is expected to be debated and approved by the House later on Tuesday.
Approval of right-to-work strikes a major blow to organized labor in the United States because Michigan is a stronghold of unions.
