Hello I have recently joined a school and I am NQT I am concerned about their behavior policy and the lack of respect students have for it. The school have a yellow card and red card system. The yellow card results in a lunch time 15 minutes detention with the classroom teacher, the red card detention results in a lunch time detention with whoever is on detention duty. If students fail to attend the detention then they receive an after school detention with SLT the following day. So as a result the most I can do as a classroom teacher is a issue a red card detention. I am contentiously seeing the same students receive only red card detentions for what I would consider serious things, such as swearing at the teacher. The students do not really take this policy seriously so this leads to bad behavior in lessons. I am particularity struggling with a class, who are ok on some days but really downhill on other days. The students have told me they don't care about the red card detentions. Is this normal for a school? I have asked for support with certain classes, however all I get is the Head of Department 'having a word' with the students at the start of the lesson.
