Sexual harassment refers to unwanted sexual advances, remarks, or acts that create an offensive or hostile work environment. It can take many forms, including visual, verbal, physical, or gestures. There are two main types: quid pro quo harassment, where sexual favors are demanded in exchange for job benefits, and hostile work environment harassment, where unwelcome sexual conduct interferes with work performance or creates an intimidating environment. Sexual harassment has negative effects and can be committed by those in positions of power over victims.
