29 C.F.R. § 1620.27 : Labor — REGULATIONS RELATING TO LABOR — EQUAL EMPLOYMENT OPPORTUNITY COMMISSION — THE EQUAL PAY ACT — Relationship to the Equal Pay Act of title VII of the Civil Rights Act

(a) In situations where the jurisdictional prerequisites of both the EPA and title VII of the Civil Rights Act of 1964, as amended, 42 U.S.C. 200e et seq ., are satisfied, any violation of the Equal Pay Act is also a violation of title VII. However, title VII covers types of wage discrimination not actionable under the EPA. Therefore, an act or practice of an employer or labor organization that is not a violation of the EPA may nevertheless be a violation of title VII.
(b) Recovery for the same period of time may be had under both the EPA and title VII so long as the same individual does not receive duplicative relief for the same wrong. Relief is computed to give each individual the highest benefit which entitlement under either statute would provide. (e.g., liquidated damages may be available under the EPA but not under title VII.) Relief for the same individual may be computed under one statute for one or more periods of the violation and under the other statute for other periods of the violation.
(c) The right to equal pay under the Equal Pay Act has no relationship to whether the employee is in the lower paying job as a result of discrimination in violation of title VII. Under the EPA a prima facie violation is established upon a showing that an employer pays different wages to employees of opposite sexes for equal work on jobs requiring equal skill, effort and responsibility, and which are performed under similar working conditions. Thus, the availability of a remedy under title VII which would entitle the lower paid employee to be hired into, or to transfer to, the higher paid job does not defeat the right of each person employed on the lower paid job to the same wages as are paid to a member of the opposite sex who receives higher pay for equal work.
