Cambridge City Councilor Marjorie Decker says the impetus for the ordinance was the 2009 mass firing of housekeepers at Hyatt hotels in Cambridge and Boston. At the time, 100 housekeepers were let go and replaced with new workers who earned about half the pay and had no health benefits. The incident caused such an uproar that Gov. Deval Patrick (D) called for a boycott of Hyatt.
