Recent reports suggest that violence in the workplace is an increasingly common problem for organizations, and that violence - or the threat of it - is one of the major sources of stress at work. This text examines the causes and consequences of violence at work, and offers practical solutions for managers and organizational psychology professionals. Part one reviews the size and scope of the problem, sets out the need for intervention and policy, and considers issues such as the social psychology and organizational consequences of violence, and systems for monitoring, reducing and managing work-related violence. Part two describes case studies of organizations and settings in which such an approach has been applied. Four main occupational groups are considered: teachers, health care workers, post office workers and staff in bars and public houses. This text should be of interest to managers, occupational psychologists and anyone concerned with violence in the workplace.
