I work in a tough place in a deprived part of town. Our behaviour policy is a nightmare. You rarely find out what sanctions have been given to students, and when you follow the policy, you are supposed to give out a short DT after three warnings, followed by longer ones if they don't turn up, then a departmental DT, then a Year Head DT etc. I'm finding myself exhausted try to follow these DT rules. They are using up what little free time I have, either doing DTs or chasing students to do them. How do other similar schools deal with this, so teachers aren't run ragged by kids?
