Which behavior is an example of workplace bullying?

Repeatedly criticizing a colleague in front of others is a clear example of workplace bullying because it undermines that individual’s dignity and creates a hostile environment. Such behavior not only serves to belittle the targeted employee but can also affect the morale of the entire team, as it establishes a culture of fear and intimidation. Bullying often manifests through persistent negative actions aimed at an individual, and public criticism exemplifies this by humiliating the person in front of peers, which is a key characteristic of bullying behavior.

In contrast, the other behaviors listed—offering help to a struggling coworker, giving positive feedback to team members, and encouraging collaboration—are all supportive and constructive actions that foster a positive workplace atmosphere. These actions promote teamwork, build morale, and contribute to a more productive and harmonious work environment, which is the opposite of what constitutes bullying.
