Because of existing laws and union rules regarding termination, only an average of 10 teachers per year have been fired for incompetence or other issues, out of almost 300,000 teachers in California. Imagine, an industry which is powerful enough to have been able to prevent its workers from being terminated.
Today Los Angeles County Superior Court Judge Rolf Treu ruled that existing tenure protections prevent students' fundamental rights to equality of education, and are therefore unconstitutional.
The two CA teachers' unions were vigorously opposed to this, supporting the existing laws and rules that would leave the termination process as-is.
This has been a closely-watched case nationwide.
