Earlier this year the Culinary and Bartender Unions surveyed about 20 percent of their more than 50,000 Las Vegas casino workers. Of those surveyed, 59 percent of cocktail servers and 27 percent of hotel housekeepers said they had been sexually harassed by guests, managers or others while on the job. An unsettling number of workers —72 percent of cocktail servers and 53 percent of hotel housekeepers —  said a guest had done something to make them feel uncomfortable or unsafe.
