Sexual harassment is defined as unwelcome verbal or physical behavior of a sexual nature, especially by a person in a position of authority towards a subordinate. It can include unwanted sexual advances, requests for sexual favors, or other verbal or physical conduct of a sexual nature that explicitly or implicitly affects an individual's employment. A single incident may not necessarily constitute sexual harassment, but a number of separate incidents can if they unreasonably interfere with work performance or create a hostile work environment. Individuals who engage in sexual harassment face penalties under Republic Act No. 7877 including fines and imprisonment.
