Which of the following actions is a warning sign that may suggest aggressive behavior?

Sabotaging company equipment or property is a clear warning sign that may suggest aggressive behavior. This action reflects a potential intent to harm or disrupt the workplace environment, which can be indicative of underlying issues such as frustration, resentment, or hostility. Aggressive behavior is often characterized by actions taken that can endanger others, damage workplace property, or disrupt the normal functioning of an organization. Such behaviors can create a toxic work atmosphere and can lead to serious consequences for both individuals and the organization as a whole.

In contrast, performance reviews, participating in training sessions, and regular attendance at meetings are typically associated with positive workplace behavior. These actions imply engagement, communication, and professional development, rather than any aggressive tendencies.
