On December 13, 2021, the California Department of Public Health (CDPH), citing the Omicron variant and the need for additional protection during the holiday season, issued statewide guidance requiring face masks to be worn in all “indoor public settings” regardless of vaccination status from December 15, 2021 through January 15, 2022.
While the guidance itself does not define “indoor public settings,” the published FAQs clarify that the requirement applies to “all workplaces, regardless of whether they serve the public, or are open to the public” and that masks may also be removed “if the workplace consists of a single employee, or . . . while an employee is alone in a closed office or room.”
