The Wisconsin state capitol was the site of massive protests in 2011 during the fight to pass Republican Governor Scott Walker’s labor reforms. The following year Big Labor staged demonstrations in Michigan against Republican Governor Rick Snyder’s right-to-work bill, which ultimately passed. Now Pennsylvania’s state capitol is set to reach fever pitch, as unions plan to bus in hundreds of protestors this week to fight legislation that, if bad for union bosses, could be a boon to rank-and-file workers.
