I had an experience with a social worker once. About 3 years ago.
I was in the process of separating with DS's father. He was moving out of the family home. A row ensued one night, about 2 nights before he was due to move out. He became aggressive and threatening, and started breaking (my) things in the house. I rang the police, they came, questioned us both, and took him out of the situation. He admitted what he had done, and was cautioned.
He stayed at his parents following this, and came back when I wasn't there to collect his things.
The police notified social services - despite me asking if this case would trigger a referral and being told no.
They turned up 3 weeks later full of ridiculous questions and stated that "if you ring the police again, we will be doing a full assessment, and will not allow your child to have access with his father". What kind of idiotic statement is that? That could have just given my ex free range to trash my home, because if I called the police, social workers would return, and turn my life upside down, therefore he would know I wouldn't - I needed my ex involved in my sons life as without him, I would have lost my job, and my home. I have never ever had any concerns about him as a father, never before, and never since. As much as I dislike him, he loves his son.
I also told them that they should be speaking to him, not me, as I was not the one with the problem - as the innocent party. They said because he had moved out of the area, they had no responsibility to speak to him.
Idiots.
They did come back actually, 3 months later to inquire why my son wasn't registered at a school. He was. Just not in their authority. They then rang the school, and spoke to my mum, who is the head teacher, to confirm he attended there. She was then made aware of everything I had wanted to keep to myself. So, thanks for that social workers.
Never heard from them again, never had reason to. I wouldn't trust them as far as I could throw them. And I work in conjunction with them sometimes.
Ps. My cat shits in the bath. Regularly. It get cleaned up when noticed. Or if we have run out of wipes/toilet paper, then cleaned later that day. Bad me.
