The now-concluded month-long strike at Temple University Hospital in Philadelphia was the biggest recent flashpoint in hospital-labor relations, but it's far from the only bad blood. Hospitals in Minnesota, California and Massachusetts are involved in contentious situations with nursing unions. In Minnesota, the largest nursing strike in U.S. history could be around the corner. Fourteen nonprofit hospitals in the Minneapolis-St. Paul region could face a June 1 strike by 12,000 nurses depending on the outcome of a May 19 strike vote by the Minnesota Nurses Union. In California, the Committee for Recognition of Nursing Achievement (CRONA), an independent nursing union, has submitted a counterproposal to try to break a deadlock in contract negotiations with Stanford Hospital and Clinics and Lucile Packard Children's Hospital in Palo Alto.
