A union representing workers in Las Vegas casinos on Monday again called for all customers and workers in reopened casinos to wear face masks and for daily cleanings of guest rooms and regular testing of all workers for the coronavirus.

The Culinary Union said an order by gambling regulators last week protects dealers by requiring face masks to be worn by gamblers at table games. But the union said those same protections need to be broadened to protect bartenders, cocktail waitresses, cleaners and other workers who interact with guests.

The union is calling for the governor, Nevada Gaming Control Board and Clark County Commission, which oversees the Las Vegas Strip, to impose stricter safety measures.
