41 CFR § 60-20.4 - Discriminatory compensation.
Compensation may not be based on sex. Contractors may not engage in any employment practice that discriminates in wages, benefits, or any other forms of compensation, or denies access to earnings opportunities, because of sex, on either an individual or systemic basis, including, but not limited to, the following:
(a) Contractors may not pay different compensation to similarly situated employees on the basis of sex. For purposes of evaluating compensation differences, the determination of similarly situated employees is case-specific. Relevant factors in determining similarity may include tasks performed, skills, effort, levels of responsibility, working conditions, job difficulty, minimum qualifications, and other objective factors. In some cases, employees are similarly situated where they are comparable on some of these factors, even if they are not similar on others.
(b) Contractors may not grant or deny higher-paying wage rates, salaries, positions, job classifications, work assignments, shifts, development opportunities, or other opportunities on the basis of sex. Contractors may not grant or deny training, apprenticeships, work assignments, or other opportunities that may lead to advancement to higher-paying positions on the basis of sex.
(c) Contractors may not provide or deny earnings opportunities because of sex, for example, by denying women equal opportunity to obtain regularand/or overtime hours, commissions, pay increases, incentive compensation, or any other additions to regular earnings.
(d) Contractors may not implement compensation practices that have an adverse impact on the basis of sex and are not shown to be job-related and consistent with business necessity.
(e) A contractor will be in violation of Executive Order 11246 and this part any time it pays wages, benefits, or other compensation that is the result in whole or in part of the application of any discriminatory compensation decision or other practice.
