Prolonged closures of Disney’s California-based theme parks and limited attendance at its open parks has forced the company to lay off 28,000 employees across its parks, experiences and consumer products segment.

In a letter sent to employees on Tuesday, Josh D’Amaro, head of parks at Disney, detailed several “difficult decisions” the company has had to make in the wake of the pandemic, including ending its furlough of thousands of employees.

Around 67% of the 28,000 laid off workers were part-time employees, according to D’Amaro. The company declined to comment on how many from its parks specifically were let go.

While Disney’s other theme parks in Florida, Paris, Shanghai, Japan and Hong Kong have been able to reopen to limited capacity, California Adventure and Disneyland have remained shuttered in Anaheim, California.
