Harassment

n. bothering, tormenting, pestering

Harassment refers to a wide spectrum of offensive behavior. When the term is used in a legal sense it refers to behaviors that are found threatening or disturbing, and beyond those that are sanctioned by society. Sexual harassment refers to persistent and unwanted sexual advances, typically in the workplace, where the consequences of refusing are potentially very disadvantaging to the victim.
