Generally, the law requires equal pay for substantially similar work based on any protected characteristic under the New York State Human Rights Law, including gender, age, race, creed, color, national origin, sexual orientation, and gender identity or expression.[1]
a. Affirmative Defenses: To justify a pay disparity, an employer can assert that it was based on: seniority system, merit system, a system which measures earnings by quantity or quality of production, geographic region (no larger than a county), and a bona fide factor other than the protected characteristic (such as education, training, or experience).[2]
b. Retaliation: Employers cannot discharge, expel, or discriminate against you if you decide to file a complaint, testify, or assist in a proceeding.[3]
