Lunch supervisor/dinner lady at a secondary school?

[Pigontrampoline]

Has anyone been one or have any experience? I'm a lunch supervisor in a primary and love the job and the children. However the way the school is run and senior leadership is awful.

There's a vacancy in a high school, closer in distance and better hours but I'm unsure of working with older children. If anyone does it, are they a lot harder to reason with? More violence? Lack of respect? We deal with all this in the primary, but they are obviously young and less scary!

Have never worked as a dinner lady but have experience in another role working with a mixture of all aged children. In my experience the older children are much much worse, less willing to listen, less easier to reason with / distract from etc.
I suppose in a school setting it depends on the school, is it a standard public school or a posh grammar school? As the latter is going to have less children with problems from bad backgrounds etc

That's what I thought @Nogodsnomasters , it's a public school and a very big one at that.

Might not be great then.
