Everyone has different standards. Some people have outside support that help with that shit. However when I recently had my 2 year olds health visitor check I apologised for the mess (not filth, bits of that mornings cereal on the floor, toys everywhere) to be told "oh we actually get concerned about immaculate homes". But I doubt any of this was about social services seeing a clean home and bouncing on their merry way. They genuinely failed poor Arthur for the mere fact alone no one questioned him alone about the bruising. He told the school he was scared his father would kill him, there is no doubt in my mind with the right, trained professional questioning him alone, he could have opened up further and elaborated why he felt such a way. No child should ever feel their parent is going to kill them. He wasn't a teenager caught smoking a cigarette saying "oh shit my dad's gonna kill me". He was 6 years old, children can be quite literal at that age.
There is no excuse, no more "lessons to be learnt". It seems to be a get out clause. The system needs a complete refresh, these "managers" are paid far too much, for doing very little in comparison to the ground workers. Threaten them with cuts to their pay packets! They will soon get off their arses. Also too many very young, "text book style" social workers around who just tick the boxes and haven't got a clue about child psychology (some of the younger ones barely even know how to communicate with children) or even have much life experience (which I feel is VERY important).
