The most effective action to deter workplace violence in a security setting is increased visibility of guards. The presence of security personnel serves as a powerful deterrent, as individuals are likely to think twice before engaging in violent behavior when they see trained guards actively patrolling the area. This visibility creates a sense of safety for employees and bystanders, as it signals that there is an immediate response capacity in place.

While security training for workers, monitoring security cameras, and communication with nearby police are all important components of a comprehensive safety plan, they may not be as immediate or impactful in deterring violence as the physical presence of guards. Training can educate employees on how to react in dangerous situations, and monitoring cameras helps to gather evidence and analyze incidents after they occur, but these actions do not prevent the initial act of violence as effectively as having visible security personnel on site. Communication with police is essential for response after an incident, but the aim is to stop violence before it happens. Therefore, increased visibility of guards stands out as the proactive measure that most directly influences behavioral deterrence in a security environment.
