Members currently receive health insurance and earn about $26 hourly, including benefits, union spokesperson Bethany Khan said. Negotiations have been underway since April over topics such as pay and working conditions. Caesars and MGM Resorts did not respond to emailed requests for comment.

A spokesperson for Wynn Resorts declined to comment.

The union’s deadline comes after yet another unsuccessful round of negotiations with the three casino companies. In Las Vegas, the 18 properties that could be impacted by a strike are Aria, Bellagio, Excalibur, Luxor, Mandalay Bay, MGM Grand, New York-New York, Park MGM, Caesars Palace, Flamingo, Harrah’s, Horseshoe, Paris Las Vegas, Planet Hollywood, The Cromwell, The Linq, and Wynn and Encore Resorts. Teachers kick off strike in Portland, Oregon, over class sizes, pay and resourcesĪ walkout would be the latest in a series of high-profile labor unrest actions around the country - from walkouts in Hollywood to UPS’ contentious negotiations that threatened to disrupt the nation’s supply chain - and would follow hospitality workers walking off the job last month at Detroit’s three casinos, including MGM Grand Detroit.
