'So, historically, SS have a non judgemental stance on different parenting styles and seem unable to differentiate between benign neglect and downright abuse.'
I am not trying to devalue your point but it's not as simplistic as that. There has been a trend in social work training to ensue that there is no inequality in treatment based upon class or economic status, so that while a family may be scruffy or whatever, it is their level of care of the children which is to be judged etc. In principle this is fine if applied properly but what gets lost is what is an acceptable level of care and when does 'scruffyness' equate with neglect.
I think social work has lost its way and have banged on about this on this thread so excuse me if I am repeating myself....but it has not moved with the times. Social services are not really dealing with families in the truest sense of the word now, they are dealing with mothers in relationships with any number of men, none of whom are the father to all the children. They are scared of making a value judgement because their training tells them they shouldn't. However they SHOULD make a judgement and that judgement should be about what is an acceptable level of parenting.
The thresholds for intervention into families are set too high. I also think social workers don't have the training to assess risk sufficiently well. This is a key part of training probation officers now who assess and manage very high risk of offenders. This has created a very skilled set of professionals (yes they also make mistakes too but the service is much more modernised in outlook.)
SW should take a lead from probation and modernise it's outlook. Train the staff to spot and assess and reassess risk, to spot changes in risk factors such as the news a new boyfriend is on the scene. Who is he? What is his criminal record etc.
I could go on but I disagree with Laming who essentially thinks social work is set up correctly. It's not. There are not enough specialists trained in child protection and too many staff juggling caseloads where there may be mild neglect right up to sexual abuse in different cases. Procedures aren't clear and the focus on always keeping the family together is a flawed one.
Anyway forgive my blathering, I could write a bloody thesis on this if I put my mind to it! Have so much anger and outrage at the crap social workers in this case. And Yes I have been one and so I know.
