Which of the following is an indicator of potential workplace violence?

Threatening behavior is a well-documented indicator of potential workplace violence. This type of behavior can manifest in various ways, such as verbal threats, aggressive posturing, or actions that suggest a willingness to harm others. Recognizing these warning signs is crucial for maintaining a safe work environment.

In contrast, the other options typically do not signify a risk for workplace violence. Excessive laughter is generally associated with positive interactions and a friendly atmosphere among employees. Team collaboration is often indicative of a healthy workplace where individuals work together effectively, contributing to a shared goal. Increased productivity usually reflects positive motivation and engagement among employees. Thus, while these behaviors can contribute to a positive workplace culture, they are not associated with the risks related to workplace violence.
