Also, in many states (including Mass.) tenure does not exist. Even with
tenure a "dead wood teacher" can be removed if they are not performing. What
people don't realize is it is the ADMINSTRATOR's JOB AND RESPONSIBILITY to
oversee and remove unqualified teachers. They have the means to do so. I am
tired of teachers bearing responsibility for administrators' lack of using
that authority. In Mass. it is particularly bad -- teacher bashing is a
popular sport !!
