Tips to fight sexual harassment at workplace:
Understand and become familiar with the organization's policy on sexual harassment
Observe and be aware of engaging in potential sexual-harassment behaviors or incidents at work
Examine your behaviors, gestures, and comments. Ask yourself, "Could I unknowingly be encouraging sexual interplay by the way I interact or communicate?"
Confront the sexual harasser immediately. Tell him/her that you find that type of attention offensive
If you know someone who is being harassed, give him or her, your support. Encourage the recipient to talk about it and to take immediate action to stop it.
