I went to do supply in a class today to be told the TA was taking the class for the day - not HLTA, just TA. I was then put into another class that needed a supply teacher, but I was still fuming at the fact that a TA was taking the class in the teacher's absence. This TA does the PPA cover for the class as well. I know it boils down to cost, but something isn't right! Sadly it's something I am seeing more and more. No wonder there is no supply work!
