Courts and employers generally use the definition of sexual harassment contained in the guidelines of the U.S. Equal Employment Opportunity Commission (EEOC). This language has also formed the basis for most state laws prohibiting sexual harassment. The guidelines state:

Unwelcome sexual advances, requests for sexual favors, and other verbal or physical conduct of a sexual nature constitute sexual harassment when

submission to such conduct is made either explicitly or implicitly a term or condition of an individual's employment,
submission to or rejection of such conduct by an individual is used as the basis for employment decisions affecting such individuals, or
such conduct has the purpose or effect of unreasonably interfering with an individual's work performance or creating an intimidating, hostile, or offensive working environment. (29 C.F.R. § 1604.11 [1980])
A key part of the definition is the use of the word unwelcome. Unwelcome or uninvited conduct or communication of a sexual nature is prohibited; welcome or invited actions or words are not unlawful. Sexual or romantic interaction between consenting people at work may be offensive to observers or may violate company policy, but it is not sexual harassment.
