Supervisors and Managers are held to a high standard of behavior:
They are placed in a position of authority by the employer and must not abuse that authority.
Their actions can create liability for the employer without the employer having any opportunity to correct the harassment.
They are required to report any harassment that is reported to them or which they observe.
They are responsible for any harassment or discrimination that they should have known of with reasonable care and attention to the workplace for which they are responsible.
