Which of the following is an example of sexual harassment in the workplace?

Unsolicited advances of a sexual nature clearly illustrate sexual harassment in the workplace because this behavior violates individuals' rights to a safe and respectful environment. Such actions can create a hostile work atmosphere, making it difficult for the victim to perform their job effectively. Sexual harassment includes unwelcome verbal or physical conduct of a sexual nature, and unsolicited advances are a prime example, as they are not only inappropriate but can also lead to legal repercussions for the offender and the organization if not addressed properly.

On the other hand, providing constructive feedback to employees, conducting performance reviews, and promoting employee engagement activities are all standard professional practices aimed at improving workplace dynamics and employee performance. These activities, when conducted appropriately and respectfully, do not fall under the category of harassment.
