Terms of the new five-year contracts haven’t yet been released, but the Culinary Workers Union said the agreements provide significant pay raises and safety improvements. The workers include the housekeepers and utility porters who work behind the scenes to keep the Strip’s mega-resorts humming, and the bartenders and cocktail servers who provide the customer service that has helped make Las Vegas famous. Taken together, the pending agreements cover more than 30,000 hospitality union workers who had threatened to walk out in the pre-dawn hours Friday if negotiations failed. LAS VEGAS (AP) - MGM Resorts International, the largest employer on the Las Vegas Strip, has joined rival Caesars Entertainment in reaching a tentative deal with the Las Vegas hotel workers union to narrowly avert a sweeping strike.
