Preventing occupational disease and injury, second edition. Levy BS, Wagner GR, Rest KM, Weeks JL, eds. Washington, DC: American Public Health Association, 2005 Jan; :253-256
A significant number of workplace fatalities and injuries occur each year in the United States. In any given week, approximately 20 workers are murdered and thousands are assaulted while working. The definition of violence in the workplace includes verbal threats, threatening behavior, physical assault, and homicide. Four basic types of workplace violence, defined by the relationship between the victim and the perpetrator, have been identified: 1. Type I-Violence by strangers where the assailant has no legitimate business relationship to the workplace (for example, entering the workplace to commit a robbery). 2. Type II-Violence by customers (current or former) or clients (patients, prisoners, students, passengers), usually to those who provide direct service to the public. 3. Type III-Violence by current or former co-workers/employees, supervisors, or managers who often seek revenge for perceived unfair treatment. 4. Type IV-Violence by an assailant who confronts an individual in the workplace with whom an outside personal relationship exists.
