Vernon - The majority of a diverse group of healthcare professionals at Rockville General Hospital (RGH) today voted for union representation in a National Labor Relations Board (NLRB)-supervised election. The outcome is a win for the bargaining unit of approximately 150 nursing assistants, maintainers, unit coordinators and others at the Prospect Medical Holdings, Inc.-owned acute care facility. Members of the organizing committee who spearheaded the union drive are looking ahead to first-ever negotiations with the for-profit company's local Eastern Connecticut Health Network (ECHN) management.
