The law requires an employer to post a notice describing the Federal laws prohibiting job discrimination based on race, color, sex (including pregnancy and related conditions, sexual orientation, or gender identity), national origin, religion, age (40 and older), equal pay, disability or genetic information (including family medical history or genetic tests or services), and retaliation for filing a charge, reasonably opposing discrimination, or participating in a discrimination lawsuit, investigation, or proceeding.
The “Know Your Rights: Workplace Discrimination is Illegal” poster, prepared by the U.S. Equal Employment Opportunity Commission (EEOC), summarizes these laws and explains how employees or applicants can file a complaint if they believe that they have experienced discrimination.
These posters should be placed in a conspicuous location in the workplace where notices to applicants and employees are customarily posted. In addition to physically posting, covered employers are encouraged to post the notice digitally on their web sites in a conspicuous location. In most cases, electronic posting supplements the physical posting requirement. In some situations (for example, for employers without a physical location or for employees who telework or work remotely and do not visit the employer's workplace on a regular basis), it may be the only posting.
