SAN FRANCISCO – More than 1,000 workers at San Francisco hotels walked off the job and will last until union members say they get new contracts honoring their demands. Workers held signs and picketed outside the Hilton San Francisco on Monday in a strike that’s also affecting Hyatt and Marriott hotels throughout the city. Some of the city’s most well-known hotels, including the Westin St. Francis, the Palace Hotel, and a handful at SFO, are affected.
