Wynn Las Vegas will require employees to either receive a COVID-19 vaccination or show they’ve tested negative for the virus on a regular basis.

The company announced the new policy Thursday, saying that 60% of employees have already been vaccinated.

For employees who do not get vaccinated, they will have to show weekly negative COVID-19 tests.

“Our primary goal is to create the safest possible environment at Wynn, for both employees and guests,” Wynn Resorts CEO Matt Maddox said in a statement. “Vaccination rates are increasing throughout the country, and requiring our employees to either be vaccinated or tested on a weekly basis will make Wynn one of the safest vacation destinations in the U.S.”
