On August 25, 2021, Cal/OSHA issued a press release which encouraged employers and workers to follow the recent update from the California Department of Public Health (CDPH) recommending that all individuals wear face coverings while indoors regardless of vaccination status (August 25 Recommendation). The full text of the Cal/OSHA press release is linked here and the CDPH guidance is available here. The practical impact of the August 25 Recommendation is to encourage (but not require) that businesses go beyond the current Cal/OSHA ETS (our analysis of which is linked here) and reimplement a requirement that even vaccinated employees to wear face coverings indoors.
