To answer a few points:
I agree the turn over of staff is probably high, but not sure that’s not a reason to do something.
I also agree, as I set out in my OP, there is a cost burden. Again, not sure that’s not a reason to do something although accept it could be too high a burden for some places.
In case there is a suggestion otherwise, I do remain responsible for my kids at these places. I may have a coffee, but I certainly don’t sit and scroll on my phone/engage in deep conversations with others. However, some of these places are huge and you can’t see all around them. You will not have eyes on your child at all times. Not unless you are allowed in the structure and stay with them the whole time (I’ve done that in places where it is allowed).
Someone mentioned about it helping inform the wider recruiting process, which I agree with. However someone else mentioned about someone whose offences don’t appear. I don’t pretend to understand how these things work but that is a shocking story!
I assumed, like another poster that this type of role may be attractive to a sex offender and requiring a DBS would discourage application.
If anyone knows how to report the post (someone explained I had put it in wrong area or shouldn’t have posted at all), do let me know. But I’m going to try and raise with mods. @moderators
Oh and for the “bless need a few more signatures” comment, it’s not my petition, I hadn’t even noted the number it was on and I’m hoping you’ve made your day better by being condescending!
