Violence has been defined as the expression of intentional use of physical force and compelling action against another person or oneself which either results in or has a high likelihood of injury or death. For workplace violence, the National Institute for Occupational Safety and Health (NIOSH) defines this as “violent acts (including physical assaults and threat of assaults) directed toward persons at work on duty.”1 It can occur at or outside the workplace2. The type of violence problem includes suicide, threats, verbal abuse, physical assaults and homicide. In general, we usually pay less attention to violence because of lack of a clear definition of the problem.3 Thus, work-related violence recently has been recognized as a major public health problem.
