This is a thoroughly updated edition of The Prison Officer (2001). The aim of this book is to provide an accessible and interesting guide to the world and work of the Prison Officer, showing the centrality of staff-prisoner relationships to every operation carried out by officers. So little has been written on prison officers (in comparison to prisoners) and this book addresses the gap. This book will be of relevance to anyone with an interest in the work of a prison officer, and essential reading for any established and aspiring officers.
