A teachers' union in Florida has sued the state in an effort to halt next month’s planned restart of classroom instruction, which it says poses an “imminent threat to the public health, safety and welfare” of its members, students and parents.

Citing the state’s position as a leading US coronavirus hot spot, the Florida Education Association (FEA) argues in its lawsuit that in-class instruction violates the state constitution’s guarantee of a “safe” education for children.
