As of Nov. 21 all employers of more than 15 employees must update their EEOC posters. There are two ways that you can accomplish this: 1) print out the update supplement 2) order new posters.
DO NOT PAY FOR POSTERS! The government will provide them for free at their website
U.S. Equal Employment Opportunity Commission (EEOC)
