I've worked alongside ss in child protection for many years although I'm not a sw myself. I've seen sw display bias towards people of different ethnic backgrounds, and I guess where individual standards of care where one person might feel is neglectful and another may see it as just less than ideal. I've only seen one case where children were removed because a parent was perceived to be under the influence but was actually having a side effect to properly prescribed and appropriately taken medication. But in the former instances children were never removed, and in the latter the parents social worker had resolved the matter by lunchtime the following day and the children were back home. Sw are not infallible, there's a certain amount of gut instinct and judgement that goes into doing the job just by its nature but in the overwhelming majority of cases I've witnessed, the children have been removed amidst genuine concern and I've been able to see the sw perspective even though the parent felt very differently about it.
At the end of the day, sw have to work first and foremost to help maintain a family through support, resource and education. If there's a significant risk to the child that means the child is unsafe at home then they will need to be removed and a sw will need to have this argued before a court that it's in the best interests of the child to be taken into care considering the trauma of being removed from their parent and their home. At risk management conferences there's a table of professionals who work with the family who need to vote on whether or not they feel the child can safely stay at home so they can outvote the sw though I've never seen that happen because the sw needs to outline their reasoning.
So for me, to get to the point of actually removing a child - there needs to be enough of a concern to merit it otherwise the sw will be turned down in their request. And I guess with the nature of the job it is best they err on the side of caution. The consequences of missing something and being too lenient can be catastrophic as we all know.
I will say though that it can be especially difficult for parents who have already had a child removed- it's such a traumatic thing to have to go through and it makes complete sense to me why you'd want to fight tooth and nail (and might then be secretive) to keep your children with you. I can't think of anything worse than being separated from my little boy.
I also think the cases that are really especially ethically difficult are ones involving domestic abuse where a lot of pressure is put on a woman to leave an abusive partner, but we know that that can actually make it even more dangerous for her to make that move. So in a sense it's damned if you do damned if you don't.
For me the entire system needs a massive overhaul to be honest. I'd like to see caretaking roles come in to replace say adoption (more like long term fostering) so a child can very much be part of a family without severing their links to their biological family until they're old enough to decide if that's something they want for themselves. I think it might give people more time to get their lives in better shape as well. I've worked with women who have had their baby removed reasonably quickly (for drug and dv related reasons) and that child was immediately moved towards adoption (the system is geared to move younger children in that direction faster due to them being more likely to being adopted and this being seen as the ideal outcome)
By the time the child was adopted that mum was sober and had managed to safely leave the relationship but then had no legal rights to get her child back. Which had been her motivation all along. It did make me wonder what would have happened if she'd been given more time but the system was stacked against her. A slightly older child would have been in care for longer and probably would have been returned to her.
