I have real sympathy for DUs support crew.
I have always said that I want my DC to know that I am there for them, whatever comes, whatever they've done and however that makes me feel, that I would be there to back them up or help then face the consequences etc. I can't criticise his parents etc for doing what I hope I would do, even if I did not agree with my DC choices or behaviour I would not abandon them I hope. (I would however expect to behave according to the same rules as everyone else and not expect to have special chairs brought in for me).
As I said earlier in the thread, DUs alleged parents appear to be well educated, qualified professionals with extensive experience of working in many fields related to the issues at hand. His dad has web hits for presentations on things like "data research" and "data management" (which is possibly a skill set NHS Fife should have sought to exploit...) and his Mum (or who is reported elsewhere to be his mum) has allegedly previously worked in counselling and in hospitals herself.
While they may have originally thought they were supporting their child as they sought to stand up for themselves against bullying and harassment at work, they cannot have failed to realise that the issues were much broader, complex and less one sided than they may have originally thought once NC started speaking on Friday.
I can put myself in their shoes a little bit and feel real sympathy for the situation in which they find themselves.
