Yes unions are bad and if we have less union then everything would magically be better. Also if we continue to burn coal and nobody takes the Jab we'd all be smarter or something.

This is the "welfare queen" dog whistle of anti-union propaganda. Please stop spreading it.

Yes, school management has to genuinely document an "underperforming teacher". There is a full legal process that has to be followed and it takes time. Too bad, so sad.

However, the problem is that school management doesn't want to produce that "documentation". It is genuine work and has the downside of maybe exposing that the teacher isn't underperforming and now a countersuit is incoming. In addition, attempting to fire a teacher almost always causes a kerfuffle in the community unless the teacher is complete garbage. And, see, if you, as a superintendent cause a kerfuffle, that is going to hit the local news and the Internet and is going to be a negative mark when you want your next job (superintendents tend to move on while most teachers do not).

So, what your little shibboleth is advocating for is unlimited authority by the superintendent to punish anybody they deem a "troublemaker"--which is any teacher with the temerity to do something that might get in the way of their next promotion. And that optimizes for teachers who simply don't rock the boat under any circumstances irrespective of any teaching skill or educational results.
