I doubt it.
For those who have repeatedly mentioned the behaviour policy, in my school, the behaviour policy states
Warning
Miss 5 mins of break
Continue this to a max of 15 mins (whole of break).
If they end up going into missing lunch too, we phone home.
There are some children who would be onto a phonecall home by 9.15 every morning! If we stuck doggedly to that.
We're also expected to use our professional judgement to intervene and prevent it from getting that far. So no, not every little thing will he detailed in the behaviour policy.
For some children, the first warning is enough. For many more, losing 5 mins of break is enough (and they can earn it back of they manage themselves for the rest of the session). For some children, it is preferable to move them than take all their breaktimes off them every day for talking! And kinder.
Some children will ask to move to they're not tempted to talk. Some are just chatterboxes!
I give some of my 'persistent offenders' the choice of where they would like to sit instead to enable them to manage themselves. That can work.
Whether it's humiliating or not depends on how it is done. I don't move children as a punishment unless they are being persistently unkind to others. I tell them that, at the point their friends are asking to he moved away from them so they can work, they really need to be thinking about their choices. If children are telling me they can't concentrate because a child is talking and are asking to be moved, what am I supposed to do? It's easier to find space for 1 child who is talking than 5 who are being disturbed by them.
Because whatever you think about moving children, it doesn't do their self esteem much good when 5 other children are asking to be moved away from them because they won't stop talking either.
