Las Vegas (AP) -- The union representing thousands of hotel and restaurant workers in Nevada has reached a tentative agreement on a five-year contract with its largest employer, the union and MGM Mirage said. The deal between the Culinary Workers Union Local 226 and MGM Mirage Inc. was reached late Wednesday after a 10-hour bargaining session, Culinary political director Pilar Weiss said. The deal ended a nearly two-month stalemate. The union had approved a strike authorization vote for next month.
