Despite angry protests at the state capitol, Michigan's Governor Rick Snyder signed a right-to-work statute into law on December 11. Michigan joins 23 other states in exercising the 65-year-old option under the Taft-Hartley amendments to the National Labor Relations Act to prohibit “union security” clauses (in general, clauses that require employees to pay dues to a union as a condition of employment) in collective bargaining agreements.

The new "Workplace Fairness and Equity Act" covers most public and private sector employees (with the exception of police and fire) in prohibiting any requirement that an employee join a union, or pay dues to a union, as a condition of employment. The Act applies to any "agreement, contract, understanding, or practice that takes effect or is extended or renewed" after its effective date, which likely will be around April 1, 2013. The full range of other federal labor rights under the National Labor Relations Act, including a union’s obligation to represent all bargaining unit employees regardless of whether an employee is a dues paying member, are unaffected by the new Michigan law.

In addition to prohibiting future union security clauses, the statute creates a cause of action against individuals or unions who try to intimidate or otherwise coerce employees in deciding whether to become a union member or pay dues. Damages and actual attorney’s fees are provided for a violation of the statute.

As would be expected, unions and their advocates are not giving up. Court challenges to the legislation have already been filed. In addition, if the aggressive protest activity is any guide (a number of schools even closed to permit teachers to attend the rally), protracted political battles will continue in Michigan.

Since the law applies to any "agreement, contract, understanding, or practice that takes effect or is extended or renewed" after its effective date, unions currently in negotiations have a strong incentive to reach an agreement sooner rather than later. The law should give unionized Michigan employers strong leverage in any ongoing union contract negotiations to trade a long-term contract or extension desired by the union for favorable contract language and economic terms. Indeed, at least one union has already proposed a 10-year extension of its collective bargaining agreement with annual economic reopeners in an effort to salvage its union security provisions.

The question now is whether adoption of the new Michigan law proves an encouragement to other states, such as New Hampshire, where right-to-work bills have languished, to pass similar laws. That remains to be seen.
