SACRAMENTO, Calif. (AP) — California workplace regulators are considering ending mask rules if every employee in a room has been fully vaccinated against the coronavirus. But the rules under consideration Thursday frustrate business groups because they set a higher standard than the state plans to adopt soon for social settings.

The U.S. Centers for Disease Control and Prevention says fully vaccinated people can skip face coverings and distancing in virtually all situations.

California is set to follow that recommendation starting June 15. But the California Occupational Safety and Health Standards Board’s staff says conditions are different among workers and that they should wear masks unless everyone else in their workspace is vaccinated.
