As the omicron surge threatens to upend months of careful planning to bring kids back to the classroom this year, Gov. Gavin Newsom and state leaders scrambled this week to help schools solve crippling, infection-induced labor shortages — while students, parents and teachers continue to worry that not enough is being done to make schools safe.

Newsom signed an executive order Tuesday allowing schools more flexibility to hire retirees and extend substitute contracts to fill the gaps. It expires at the end of March, he said at a news conference.
