Shikha Dalmia of Reason looks at big labor's effort keep Michigan a second rate economic state through a series of referendums on the statewide ballot next month: We've seen Gov. Scott Walker's battle in Wisconsin and the Chicago Teachers Union strike next door. Now in Michigan comes another Midwestern political showdown that will carry enormous implications for the role of unions in American life. [media-credit name=" " align="alignright" width="300"][/media-credit]The Michigan Supreme Court recently approved the placement of a proposed constitutional amendment on the November ballot. If passed by voters, the so-called Protect Our Jobs amendment would give public-employee unions a potent new tool to challenge any laws—past, present or future—that limit their benefits or collective-bargaining powers. It would also bar Michigan from becoming a right-to-work state in which mandatory union dues are not a condition of employment. The budget implications are dire. Michigan public unions began pushing the initiative last year, shortly after Michigan Gov. Rick Snyder—facing a $2 billion fiscal hole—capped public spending on public-employee health benefits at 80% of total costs. This spring, national labor unions joined the amendment effort after failing to prevent Indiana from becoming a right-to-work state. Bob King of the United Auto Workers said that Michigan's initiative would "send a message" to other states tempted to follow Indiana's example. The UAW, along with allies in the AFL-CIO and the Teamsters, poured $8 million into gathering 554,000 signatures—some 200,000 more than needed—to put Protect Our Jobs on the Michigan ballot.
