Having worked in a K-8 public school, I can assure you this Chairman is completely out of touch. There is more to being a teacher than just showing up for work, and having an incompetent teacher makes the students further behind in their studies, lower in their test scores, the students (namely the middle school aged students) can sense when someone cannot handle classroom discipline and as a result you end up with multiple incidents where students get hurt in the classroom. I've witnessed this happening, not only did the parents hate it, the students hated it more. What's worse, low income students look to their teachers as a role model for what you can do with your life with an education. An incompetent teacher only sets a really bad example to these students. The other teachers resent it because they have to pick up the slack for what the incompetent one is not doing. This is definitely NOT a good idea.
