Union members from around the country rally at the Michigan State Capitol to protest a vote on Right-to-Work legislation December 11, 2012 in Lansing, Mich. - 

This week Michigan's Republican Governor Rick Snyder signed a law that made Michigan the 24th "right-to-work" state in the country. While the legislation is seen as a blow to the state's unions, Governor Snyder told Marketplace that he thinks the new law will advance Michigan economically overall:

"This is about more and better jobs coming to Michigan. If you look at Indiana, they did similar legislation in February, and literally thousands jobs -- new jobs -- are coming to Indiana where this was a major consideration in company's decision to move to that state," said Governor Snyder.  

The news of Michigan's "right-to-work" law reignited a debate about the role of unions in our country today, but how is the issue playing with the American public? According to Gallup, a slight majority -- 52 percent -- of Americans support unions, though only 17 percent are part of a "union household." 

"As is true with so much of America today, [support of unions] is highly divisive along partisan lines," said Gallup editor-in-chief Frank Newport. "If Republicans support right-to-work laws they are playing to their base. Democrats who oppose them are playing to their base."
