I share the general revulsion... obviously.
I have to say though. In my experience, the 'system', sets up tensions between practitioners which can lead to disaster.
Whilst still working as a Career Adviser, I met a girl of about 15, in a school for children with Moderate Learning Difficulties. During our conversation, she made a 'disclosure', which I found very disturbing. So, I approached her Form Teacher and asked if he knew about this issue. He immediately went into 'shut down', insisting that he could not discuss this stuff as it was 'confidential' etc. It took me a few minutes to get this clown to realise that it was no longer confidential as the child herself had told me, and that I needed to know whether the school was aware and whether appropriate action/referalls etc., had been taken. "Why do you need to know?" was his reply. I could have choked him. "Because if YOU have not taken appropriate action..then I NEED TO!!! I AM ALSO RESPONSIBLE!!" The penny finally dropped and he confirmed that appropriate action had been taken and the child was subject to a Care Order etc.
That sort of jealous 'ownership' of information, combined with 'Professional One Upmanship'. is a part of the systemic problem.
