For social workers have an intrinsically difficult, if not impossible task. They are very different from doctors. People consult doctors because they want to, or manifestly need to. They do not in the same way consult their social worker. They are referred to a social worker, whether they like it or not: the social worker is 'put onto' them. The social worker is therefore extremely likely to seem intrusive and interventionist, imposing his own values on the reluctant or uncomprehending client.
