Which of the following is a warning sign of potential workplace violence?

Fascination with weapons and acts of violence is a significant warning sign of potential workplace violence. This behavior often indicates an unhealthy preoccupation that can manifest in various ways, such as talking excessively about violence or showing interest in violent movies, video games, or news stories. Individuals who exhibit this kind of fascination may be more likely to view violence as a solution to problems or conflicts, which raises serious concerns about their potential for acting out in harmful ways.

While other behaviors, such as being a "loner," expressing feelings of guilt or shame, and having a history of frequent absences, may also warrant attention and could indicate underlying issues, they do not directly suggest an intent to commit violence. Specifically, the fascination with weapons and violence is a more definite indicator of a concerning mindset that could lead to violent actions, making it a critical warning sign for identifying at-risk individuals in the workplace.
