Sexual orientation harassment is the same as sexual preference harassment. This means that an individual is discriminated against, or harassed because of the type of sexual partners they prefer. For instance, if several individuals at work gang up on and make fun of a woman because she is gay - this is sexual orientation harassment. This is illegal and the woman may have grounds for a complaint or a lawsuit. With the latter option, contacting a knowledgeable discrimination attorney is a good choice. He or she can explain to the victim how discrimination laws work and whether or not the case is strong enough to pursue in a court of law.
