Michigan is about to become the 24th state to enact right-to-work legislation, joining a list of mostly conservative and free-market states. Michigan is one of the first major union states to go this route. In the other states, the right-to-work status typically acts as a deterrent to union-forming.
Governor Snyder, who favored unions and previously opposed right-to-work efforts, seemingly had a change of heart after having to deal with them for a couple of years:
Public employee unions opposed Snyder's moves to put more teeth into emergency manager laws that would enable swifter action to rescue cities and school districts that bungled themselves into insolvency. In Detroit, Mayor Dave Bing and a spineless City Council were stonewalled by employee unions at every turn, slow-walking needed reforms and cost-cutting while the city burned through cash at a frightening rate. As a result, Snyder's patient attempt to help fix Detroit via consent agreement instead of imposing an emergency manager has failed. To top it off, Snyder found himself having to fight off Proposal 2, the ill-advised November ballot attempt to stuff a bag of goodies for organized labor into the Michigan Constitution.
