Unions representing 17,000 workers at Walt Disney Co.’s Disneyland Resort in California have told the state’s governor they are not convinced the theme park will be safe enough to reopen by the company’s July target date.

In a letter to Governor Gavin Newsom on Thursday, the unions said they had been in discussions with Disney since mid-March when Disneyland was closed to help curb the coronavirus pandemic. The resort in Anaheim, in southern California, houses the Disneyland theme park and the California Adventure Park, both of which the company aims to reopen July 17.

“Unfortunately, despite intensive talks with the company, we are not yet convinced it is safe to reopen the parks,” the letter from the Coalition of Resort Labor Unions said.

A Disney spokeperson said Friday the company had put the safety of workers and guests “at the forefront of our planning.”

“We look forward to continued dialog with our unions on the extensive health and safety protocols, following guidance from public health experts,” the spokesperson said.
