Bad Teacher

Megan McArdle has long and misleading post up on why we have to fire teachers, in large numbers and immediately, and, among other things, makes the point that it's too hard firing bad teachers.  Well, here's a story about a teacher who has twice been fired for no good reason. She was once a porn star but there is no suggestion that she wasn't and isn't an effective teacher. This is why teachers require protection from being fired. And, I would add, why all workers need protection from being fired for no good reason.
