We have this rule in my school (SEND).
Most of them are very sensory and like to hug and touch people.
Unfortunately there has been some physical violence and SA and false claims of both.
So we took the no hands on approach.
At first we were quite strict on it (police and SS were involved so we had to be) and then once they understood the rules a bit better we would just focus on the couple that needed to not touch/be touched and over look certain things.
If someone gives someone a quick hug and a pat on the back, we’d look the other way.
But if someone gives someone a hug that we think is for inappropriate reasons we will just say “no hands on” and then they stop.
Even if we hadn’t had negative associations with it (like violence, bullying or SA) it is still a good idea and some people don’t like to be touched.
We find our guys often think that complete strangers want to hug and hold hands etc and so it’s good for teaching them to ask for consent and have boundaries too.
I do think most kids need to touch each other and it’s sad and unfair if it a proper ban but it’s most likely similar to my school where accusations have been made so have to be careful but they won’t be too hot on it.
