Well you seem to be discounting what would be overtime pay in other non salary jobs. Just the 10 months bit I am quibbling about really. I agree with you in all other areas.
We have thrown tons of money in our local district thanks to the casinos. Yet I still get letters from my son's teachers saying something like, "You're son was disrupteve again today."
No **** B word, perhaps because he is bored with your class. I taught him that years ago. Oh and he knows the difference between you're and your and can spell disruptive.
