Work-related violence has significant cost to individuals, organisations and the UK economy. Work-related violence includes verbal abuse, threats, physical assaults and more covert acts of bullying from co-workers. Research is now needed to better understand these risks to employee well-being. A key element of this study is the examination of both insider- and outsider-initiated violence in the same study. With both a longitudinal design and a comprehensive set of questionnaire measures our aim is identify potential candidate variables for future intervention studies. We will examine the consequences of violence in a number of sectors, considered to be both high-risk or low-risk work environments.
