The system is broken and the glue being used to fix it is not only not holding, it is making things worse. The sweet little children hired to be the new teachers won't cut it. They are young and idealistic with no true idea as to what they will be facing. Their supervisors won't want to be bothered helping them. It is just easier to write them up, U-rate them and get them out. After all, there is another new batch waiting in the wings for their jobs.
Even though I teach math, I am not good with tedious numbers and never balance my checking account. When things get out of hand,I just open a new account. It is easier. These new teachers will be like that bank account I no longer need, tossed out for a new one, a fresh start. The new one won't be any better because the history that caused the first one to be chucked will repeat itself. And, the ease of replacement is still there.
