Sexual harassment at work can create a hostile work environment that affects everyone beyond the immediate victim. If you witness someone sexually harassing a co-worker, you should do something about it. How you react can affect what happens in the future and how the company handles the situation. 

The National Partnership for Women & Families explains that if you see sexual harassment taking place, you should support the person as much as possible. This may involve stepping in and stopping the harassment if you feel it is safe to do so. However, there are other steps you can take if you do not feel safe with a direct intervention. 

Alert someone in authority 

You can always get the attention of a supervisor, human resource manager or someone else in an authoritative position to handle the situation. You do not have to wait to report the incident later. Get someone involved right now to put a stop to things before they go any further. 

Document the incident 

Make sure that you write down what you saw and what happened. You should do this as soon as possible so that you remember details and your account is more accurate. Keep this to yourself until you get permission from the person who suffered the harassment. 

Provide support 

You should also provide support to the person. Let him or her know what you saw. Explain you are there to offer whatever he or she needs. Make sure that the person knows you are willing to be a witness and speak up about what you saw.
