Squeezed by limits on attendance at its theme parks and other restrictions due to the pandemic, The Walt Disney Co. said Tuesday it planned to lay off 28,000 workers in its parks division in California and Florida.

Two-thirds of the planned layoffs involve part-time workers but they ranged from salaried employees to nonunion hourly workers, Disney officials said.

Disney’s parks closed last spring as the pandemic started spreading in the U.S. The Florida parks reopened this summer, but the California parks have yet to reopen as the company awaits guidance from the state of California.
