Is workplace violence only about disgruntled ex-employees who come back to their old jobs and shoot people?
Most media sources portray the problem in this way, which actually makes murder at work seem more likely than it really is. The number of cases involving current or former employees who come to work with guns and shoot or kill people is really quite small. Statistically in most organizations, employees are most likely to be threatened by a co-worker, not killed. Most deaths at work occur during robberies of employees, by criminals.
