Hundreds of union and non-union hospital workers and their supporters rallied on Thursday, May 8 in the Longwood Medical Area of Boston for the free and fair union elections for all Boston hospital workers. Following previous heavily publicized endorsements from Mayor Thomas M. Menino, the Boston City Council, and Ben Affleck, hospital workers received another major boost at Thursday's event from national recording artists Dropkick Murphys, who performed at the rally to show their support.
