50,000 Las Vegas casino workers to take strike vote.

The union representing 50,000 Las Vegas casino employees whose contracts will expire at the end of the month on Wednesday announced the workers are set to vote on whether to strike, a move with the potential to cripple the entire city.

The Culinary Union will hold the strike vote May 22 at a university arena near the Las Vegas Strip. A majority of yes votes would allow the union’s negotiators to call for a strike at any time starting June 1.

A strike would empty 34 casino-hotels on the Strip and downtown Las Vegas of kitchen employees, food and cocktail servers, housekeepers and other workers that are key to running a resort.

The workers’ existing contracts will expire at midnight May 31. Negotiations for new five-year contracts began in February.
