Sexual harassment is bullying or coercion of a sexual nature, or the unwelcome or inappropriate promise of rewards in exchange for sexual favors. In most modern legal contexts, sexual harassment is illegal. As defined by the US EEOC, "It is unlawful to harass a person (an applicant or employee) because of that personís sex." Harassment can include "sexual harassment" or unwelcome sexual advances, requests for sexual favors, and other verbal or physical harassment of a sexual nature.
 
Where laws surrounding sexual harassment exist, they typically donít prohibit simple teasing, offhand comments, or minor isolated incidents. In the workplace, harassment may be considered illegal when it is so frequent or severe that it creates a hostile or offensive work environment or when it results in an adverse employment decision (such as the victim being fired or demoted, or when the victim decides to quit the job).
 
The harasser can be the victim's supervisor, a supervisor in another area, a co-worker, or someone who is not an employee of the employer, such as a client or customer.
