Under new roles proposed by a beleaguered state board Friday, vaccinated workers in California will be able to cast aside their face coverings, but unvaccinated workers will have to continue to wear masks.

If passed, the Cal/OSHA workplace rules would align with the state’s reopening plans for Tuesday. But under the agency’s rules, the new proposal could not take effect until June 28. Until then, all workers must wear masks indoors unless alone in a room.
