In the end, the bills sailed through — even though some Republicans were opposed. The Senate approved a measure dealing with private-sector workers 22-16. As Democrats stormed out of the chamber, a second bill applying to government employees was passed, 22-4.
The House approved a private-sector employee bill 58-52. Both chambers are expected to approve two identical measures next week. Leaders said they would include exemptions for police and firefighters, who are covered by existing law requiring binding arbitration for their labor disputes.
A $1 million appropriation was tacked onto the bills for what a House spokesman described as implementation and worker education activities. Spending bills are legally protected from being overturned by statewide referendums.
United Auto Workers President Bob King, who joined the protesting crowd, said the bills’ passage was ‘‘a very partisan, polarizing attack.’’
A White House spokesman said President Barack Obama continues to oppose right-to-work laws.
‘‘Michigan — and its workers’ role in the revival of the U.S. automobile industry — is a prime example of how unions have helped build a strong middle class and a strong American economy,’’ the spokesman said.
