If I could change one thing about our education system that might make it better, I would require all elected officials to send their children to public schools in their home districts...
As for the whole pay thing. I am well paid, when you look at my pay compared to the average for the city where I work.

Tokie says the school will run with full staff, even if it is empty. Nothing can be further from the truth. Each school is given a staff level based on number of students. Fewer students = fewer staff. Our school lost 2 teachers this year due to shifting population patterns. Another middle school gained 4. That's the way it goes in many places. No school would hang on to teachers because the union demanded it. They may negotiate the contracted maximum size of the class (mine is 36), but the district will definitely make sure there is a minimum, as well.
