The National Labor Relations Board has charged UPMC (University of Pittsburgh Medical Center) with harassing and intimidating workers who are trying to form a union at several of its hospitals, the Pittsburgh Business Times reports. In addition, it claims the hospital network fired four workers for their union-organizing efforts. Although the NLRB and UPMC settled a complaint earlier this year based on similar complaints, the latest cases includes 19 charges of unfair labor practices. The union wants UPMC to reinstate with back pay the four fired workers, including one person who had been fired and reinstated as part of the February settlement, then fired again. UPMC has until Oct. 15 to respond to the complaints. A hearing to rule on the merits of the complaint is set for Dec. 16, but the hearing may be rescheduled because the NLRB office is closed due to the government shutdown. Article
