From a security perspective prohibited behavior is the trigger for workplace violence. It has three constituent elements:
1. Behavior that is criminal or disruptive in nature.
Disruptive meaning any action, incident or behaviour that departs from reasonable conduct
2. Behavior that is violent, or has the potential for violence.
Anyone engaging in prohibited behavior is already acting outside what is considered normative behavior, and potentially outside the law. Therefore, prohibited behavior can create a sense of danger that generates apprehension and eventually fear. If this behavior escalates to the use of physical force intended to hurt, or kill someone, or the use of intimidation tactics then trauma is quite possible.
3. Behavior that is persistent.
The term "persistent behavior" is used to differentiate from what might be a single incident of prohibitive behavior ‐ which may require investigation but only as a single episode, or multiple incidents over a period of time, thereby, requiring a mechanism to track these incidents to determine the level of risk an individual poses to businesses.
