This essay will aim to refer to the observation of professional social work practice in a crisis centre, for people with mental health problems who need short-term support and accommodation, with the goal of returning home or to a new environment. This essay will focus on the role of multidisciplinary collaboration regarding Crisis Center staff and the Crisis Resolution Home Treatment Team (CRHTT) and discuss why collaboration appears to play an important and fundamental role in social work practice. The essay will also aim to demonstrate good practices and possible strengths and weaknesses of multidisciplinary working. In the field of social work practice it seems evident that "multidisciplinary working is work undertaken jointly by workers and professionals from different disciplines or occupations" (Pearson & Thomas, 2010:342) and has evolved at varying speeds over the last 30 years, in response to central government imperatives. Evidence suggests that the mental health area was among the first professions to adopt teams of workers from different professions, and the Community Mental Health Team is widely regarded as the model for multidisciplinary working (Community Care, 2010). It appears that, in relation to social work, the distinctive quality that needs to be demonstrated is anti-discriminatory practice and a holistic approach, working with a range of situations and people having a characteristic for the development of multidisciplinary and partnerships (Higham,2006:). The Crisis Center observed is managed by a Local Council and is a National Health Service body based in a local community. The center also corresponds to the 1975 White Paper entitled "Better services for the mentally ill"... at the heart of the document... comparison with the ward: an evaluation of the Amethyst House service and home treatment team for resolution of crises: Liverpool City Council and Mersey Care NHS Trust: Liverpool.Thompson, N.
