The Warriors laid off 1,720 part-time event staff in mid-March — the largest cuts at a single Bay Area location to date during coronavirus — according to a recent state filing with the California Employment Development Department. Though the report doesn’t specify the duration of the layoffs, team spokesman Raymond Ridder told The Chronicle that the employees will return to work as soon as Chase Center is allowed to begin hosting events again. Employees were notified shortly after the NBA suspended play March 11 to help curtail the spread of the coronavirus.
