A social worker's job is to support people who need extra help to be safe and healthy. Your social worker will be one who just works with children and young people.
They'll want to make sure you're okay and getting the best care. So they'll talk to you lots, but they'll also talk to other people in your life too. Those people might include your family, teacher, foster carers or key worker.
Sometimes children aren't looked after properly or are hurt by their families. Social workers are there to help parents make changes which will keep their children safe. Especially if parents think they're doing what's best for their children but are actually putting them at risk of harm.
Some parents aren't able to keep their children safe, even after they've made changes. If that happens, the social worker will go to court and ask a judge to legally say that the children would be safer living somewhere else.
