Businesses in California remain baffled by the shifting rules over who needs to wear masks and where as the nation’s largest state fully reopens from the pandemic on Tuesday.

While Gov Gavin Newsom’s health agency has said vaccinated people won’t need to wear face coverings in many public places, state regulators following several lengthy and hotly contested debates are still drafting rules for workers.

That has some business leaders clamoring for Newsom, who will likely face a recall election in the fall, to step in and order just one set of mask rules for California’s 40 million people.

“We asked the governor to issue an executive order to align the rules,” said Lucy Dunn, president and chief executive of the Orange County Business Council. “Otherwise it’s just terribly confusing.”

With vaccinations rising and coronavirus cases low, California will end most mask rules on June 15 for people who are vaccinated while continuing to require face coverings for unvaccinated people in indoor public settings and businesses. Everyone will need to remain masked in some places such as public transit and indoor school classes.
