I imagine all hospital staff have to be vetted Izzy. Nobody with a criminal conviction would be allowed work in a hospital, and I'd say they are extra vigilant about who they employ in children's hospitals.
I'd hope so. I don't know how it works legally, if applying for jobs of any kind in particular institutions require extra checks but I'd like to presume so.
Also, I noticed in a tweet about a newspaper headline tomorrow I noticed mention of multiple abuse/assault allegations at a school as well as hospitals and the BBC - when did he visit schools? did he give speeches at some career days event or something? I don't remember ever reading about him going to schools...hmmm.
