Social workers deal with complex human situations every day. Invariably they do this with only partial knowledge of key factors, in situations that are dynamic and fast moving and often confronted by complex ethical and professional dilemmas. They need an up-to-date textbook that looks in detail at the evidence of who harms children, why people kill children and what good social work can achieve both at a micro and macro level. Featuring illustrations from practice as well as case studies and practical activities to aid learning, this book provides a holistic view of decision making as a core aspect of effective social work practice with at risk children and their families.
