Which of the following best defines workplace bullying?

The definition of workplace bullying as "a pattern of repeated mistreatment of employees" emphasizes the ongoing and systematic nature of the behavior. This understanding of workplace bullying captures the essence of harmful actions that are not limited to a one-time event but are sustained over time, affecting the well-being, performance, and morale of the individuals targeted.

In contrast, options such as collaborative conflict resolution and encouragement of friendly competition involve positive interactions that foster teamwork and productivity, which are not characteristics of bullying. A single incident of verbal disagreement, while potentially distressing, does not meet the threshold of repeated mistreatment necessary to classify it as bullying. Thus, the emphasis on the pattern and repetition in the correct definition underscores the seriousness and damaging impact of workplace bullying.
