Experts said that move would have been catastrophic for the Las Vegas Strip. The union had threatened to begin a strike in the pre-dawn hours Friday at properties along the Strip if negotiations failed. MGM didn’t immediately respond to a request for comment from The Associated Press. The union said on X, formerly known as Twitter, that the agreement followed nearly 20 hours of negotiating. The Culinary Workers Union announced the tentative 5-year agreement Thursday that it said covers about 25,000 workers at the Aria, Bellagio, Excalibur, Luxor, Mandalay Bay, MGM Grand, New York-New York and Park MGM. The Las Vegas hotel workers union reached a deal with MGM Resorts International, the largest employer on the Las Vegas Strip, on the heels of its breakthrough agreement with Caesars Entertainment.
