You can always ask! However, in UK family law the court has no power to force the local authority to change the social worker. Think about why you are not getting along. Social workers have a very difficult job to do – and they have to say some unpleasant things to parents. Will it really make any difference if it is someone else? Will they say anything different? If you succeed in getting a new social worker it is another change for your child and this is not necessarily good. At some point we all have to deal with people we don’t like and make it work anyway. Then there is the devil you know argument. The next one might be worse. Get a critical friend and your lawyer to help you think this through. It is never easy hearing someone say your house is in a right state and you don’t look after your children well – especially when you don’t beat them or deliberately mistreat them. But sometimes what you do is just not good enough even with the best will in the world. So check it out with an independent person before you carry on banging that drum.
