It's against the law to imprison people, even if they are small and behaving really badly.
So why do we have prisons, secure units and secure children's homes?
I've read a few reports, they mostly state that he had got a knife from the kitchen, he was physically restrained, the knife removed and then put in a room, watched through a window for 40 mins until he was calm enough to come out.
On this evidence, I'm with the teacher who said what else could they do?
In an ideal world a 9 year old would not be locked in a room. But when it is the rights of 1 versus the health of 500 then there is no choice.
I have also read that the school ha s a unit for children who are disruptive and are sent there by other schools. If true, then I am not suprised they have a chill out room.
It is the parent of the child who has complained.
OP
Are your concerns about whether this is a routine punishment and that your children may be subjected to it?
I would ask your children if they know about this room, the chances are they don't even know it exists.
