You can get in contact with the Contact Person in Cases of Sexual Harassment, Discrimination, and Violence or reach out to another internal or external organization that offers advice and counseling. You also have the option of speaking to your supervisor or HR representative and seeking a solution together. However, the latter will be obliged to take action. Depending on the situation, you can also arrange a one-to-one conversation with the person involved in the incident, outline how it made you feel uncomfortable, and request that they refrain from such behavior in the future. You may also wish to ask a colleague that you trust to come with you if you decide to go down this route.
