San Francisco district and unions agree on school reopening plan after city lawsuit On Saturday, the United Educators of San Francisco (UESF), a collection of several unions representing all school employees, reached a tentative agreement with the San Francisco Unified School District (SFUSD) with a phased reopening plan to force 52,000 students and teachers back into schools for in-person learning. Under the new framework, which has yet to be voted on by teachers and school workers, schools will begin to return when the county enters the “red zone” of California’s latest “Blueprint for a Safer Economy” reopening plan. The “red zone” signifies a test positivity rate of 5 to 8 percent and up to 7 daily new cases per 100,000 people.
