Sexual Harassment typically occurs in a workplace environment, but can happen within any organization. It could be on a sports team, a religious group, a yoga studio. It could be a coach, trainer, teacher or counselor.

There are two basic types: Hostile Environment and Quid Pro Quo.

HOSTILE ENVIRONMENT: Some creep makes your work life a living hell with lewd behavior, unwanted advances and so on.

QUID PRO QUO: Sounds like: "If you do things for me, I'll get you a promotion." Or perhaps: "If you want to keep your job, you'll do things for me." The creep is trying to use his (or possibly her) status and authority to coerce you.
