Which of the following describes unlawful harassment?

Unlawful harassment is characterized by unwelcome conduct that negatively impacts an individual's work environment or job performance. This type of behavior can create a hostile, intimidating, or offensive atmosphere, which is against workplace regulations and can violate employment law. When such conduct affects an individual's ability to perform their job or creates a difficult work situation, it is considered harassment.

In contrast, welcomed and supportive conduct, as well as behavior that promotes team cohesion, would not fit the definition of harassment since they contribute positively to the work environment. Unreasonable conduct based on personal preferences can vary widely in terms of impact and intent, but it does not specifically capture the essence of harassment unless it crosses into unwelcome territory affecting someone's job.
