The Culinary Workers Union in Las Vegas, the largest union in Nevada, voted to authorize a strike against major casinos on Tuesday if contract disputes continue. The Culinary Union represents over 60,000 hospitality workers in Las Vegas and is one of Nevada’s strongest political forces. Over 95 percent of workers voted to authorize a strike Tuesday, the union announced. Over 40,000 members are currently working without a contract as the union seeks better pay, benefits and working conditions in negotiations with top casino companies including MGM International, Wynn and Caesars Entertainment.
