Robotics developments: On June 1, a deal between the Culinary and Bartenders Unions and several large hospitality companies in Las Vegas, including MGM, expired. The unions represent around 38,000 workers. During negotiations over a new deal, many workers threatened to strike unless protections against automation were included, among other things. To avert the strike, individual companies, such as Caesars and MGM, have formed new deals with the unions.
