I can think of one thing that would have helped my friend.
As a legal aid lawyer, I am required to give every client a lengthy client care letter setting out my responsibilities, the chain of command within the firm, the complaints procedure and the external monitoring body. It's all there in black and white.
If SWs had a similar requirement - even a standard booklet - that would be massively helpful. My friend was fobbed off many times about the complaints process and was eventually told that the complaint would be directed straight to the SW dealing with the case. You can imagine how keen she was on that idea!
Such a booklet could also set out the rights in terms of advocates etc. My friend was told she could not have a lawyer present at the panel meeting or at any other appointment and that a lawyer would be refused access and that bringing one would cause concerns about her co-operation. She was also told conflicting information about the rights of the advocate they did use - and that advocate was refused access on one occasion. She was given incorrect information about the procedure, information which changed every time she had a meeting.
If something was given to every parent outlining the procedure and the legalities, and if there was an independent complaints process, that might help a lot of people in this situation.
Again, you have to remember that the loss of a child is the most terrifying prospect that a parent can face. There is only so much fear that most people can cope with before they just knuckle down and do whatever is necessary to get through the nightmare somehow.
Watching my friend go through this was incredibly painful and frightening. By the end I had no faith left myself that things were going to be OK - and I wasn't even the one being threatened with the loss of my child. I watched my friend go from a strong, confident woman to a terrified mess and I couldn't believe what I was seeing.
