A study was conducted to investigate reductions in the numbers of social work posts located within Child and Adolescent Mental Health Services in the UK. Results suggested that reductions in posts noted in earlier studies are continuing. Interviewees' ideas about factors contributing to the survival of such posts are summarised. The significance of the loss of posts is discussed, with an account of changing ideas about the role of social workers within CAMHS teams, and of an audit undertaken of one service lacking such a post. Conclusions are drawn concerning ways of ensuring the preservation of such posts.
