The United Auto Workers Local 174 sign stands outside their building in Romulus, Mich. on Friday, March 22, 2013. With 14.4 million members, unions still can be a potent political force at the ballot box. But protests in recent years over the passage of right-to-work laws in Michigan and Indiana, clashes over collective bargaining in Wisconsin and Ohio and a sharp drop in union elections across the U.S. have raised larger questions: Where do unions go from here? How they do mend their battered image? Can they recruit new members? And is organized labor even a movement any longer? (AP Photo/Paul Sancya)
