Shoving; yelling; intimidating; throwing things. Each and all of these are
signs of violence. And while the physical assault aspect may immediately come
to mind, workplace violence is a much broader problem. It includes any act in
which a person is abused, threatened, intimidated or assaulted in his or her
employment. And it doesn't have to happen at work. Work-related violence can
occur at off-site business functions, at work social events, in clients' homes
or away from work but resulting from work, such as a threatening telephone call
to your home from a client.

There is no room for violence in the workplace. The message is clear, if you
see it - report it. Violence and bullying can create stress, anxiety, and low
morale in employees and, ultimately affect the health of the individual and the
organization. The first step in prevention is recognition.
