Kissimmee, FL (March 8, 2012) – An Osceola Regional Medical Center housekeeper has filed federal charges against a major healthcare union for repeatedly violating federal law by refusing to allow her to exercise her right to refrain from dues-paying union membership under Florida's popular Right to Work law.With free legal assistance from the National Right to Work Foundation, Imaculada Camara of St. Cloud filed the charges with the National Labor Relations Board (NLRB).On December 8, 2011, Camara sent a letter notifying Service Employees International Union (SEIU) Healthcare Workers East officials that she was exercising her right to resign from union membership. Instead of acknowledging her request, SEIU officials rejected her letter because it was not sent via registered mail. On December 28, Camara sent a second letter, which SEIU officials again rejected, this time for not being timely.
