I was in the classes where students took pride in declaring all out war on subs, yet I stayed and worked past all of their efforts to get me to quit and always delivered my famous line "don't let this white hair fool you!"
We need to reward the "thankless job" of substitute teaching with better pay and chances for permanent positions. I look forward to the day when no student comes home saying, "I didn't learn much today... we had a sub."
Yes, the substitute teachers are to blame for their own actions. But who is legally and morally responsible for putting them in charge of the children in the first place? The principal? The superintendent? The school board?
