I'm anxious about social workers because they have the power to take DS away from us. We do our best to be good parents and to protect DS from harm, but I still get anxious, especially when he has a tumble and gets a bruise (DS is learning to walk at the minute, so this happens more than I would like).
I'm sure most SW's are sensible and don't remove children without good cause, but it's still a worry. Yes, they're human. And some people are reluctant to change their views on someone once they've made their mind up, some people are reluctant to admit when they've made a mistake, some people let their personal dislike of others influence their decisions.
Which makes me worry that if SW's did come into our lives for whatever reason, that a SW could get a pre-conceived idea that we're bad parents, and be igoring any evidence that contradicts her pre-conceptions. The whole secret court thing doesn't help with my worries. Aside from anything else, they make it illegal for you to raise hell in the press, and illegal for the press to report on a lot of cases.
I get especially anxious when I read stories about families who claim they've had children removed on flimsy grounds. I agree some of these stories turn out to be about children who've been removed for a solid reason, but it still worries me.
