The Minnesota Nurses Association and the California Nurses Association separately issued notices that they will hold one-day strikes on June 10 unless contract negotiations are resolved--collectively putting some 25,000 nurses on strike notice. Nurses in California are concerned about staffing levels impacting patient safety at five University of California medical centers (San Diego, Irvine, Los Angeles, San Francisco, and Sacramento) and four other facilities: Citrus Valley Medical Center in Covina, San Pedro Hospital, Marina del Rey Medical Center in Los Angeles and Olympia Medical Center in Los Angeles. The Minnesota nurses are targeting pay and pension issues, as well as staffing, in contract negotiations involving 14 Minneapolis-area hospitals. FierceHealthFinance
