If you experience sexual harassment at work, you may well feel powerless. What if your supervisor is the one harassing you? You know you do not hold the power in that relationship and you worry about losing your job.
People sometimes make the mistake of assuming that sexual harassment in the workplace has to come as physical contact, or it somehow does not constitute harassment. They take other types of offenses far too lightly. In fact, this is sometimes why harassers continue their treatment of others, assuming that they can't get in too much trouble if they don't cross that line.
