The nation's unions lost 400,000 members in 2012 as the percentage of U.S. workers represented by a labor union fell to 11.3 percent, its lowest level since the 1930s - declining by 0.5 percent over the last year. Michigan accounted for about 10 percent of the nation's loss of unionized workers as the Wolverine State fell to the seventh most-unionized state, from fifth in 2011. The Bureau of Labor Statistics said the biggest hit was in public sector unions, where many states and cities have cut back on their unionized workforce. Among public sector workers, 35.9 percent are in a union - down from 37.0 percent in 2011, as the public sector shed nearly 250,000 union workers. The public sector union rate is more than five times higher than that of private-sector workers. In the private sector, 6.6 percent are unionized, down from 6.9 percent in 2011. Union membership fell in 34 states. http://www.detroitnews.com/article/...nion-membership-falls-70-year-low?odyssey=tab|topnews|text|FRONTPAGE
