§ 1620.14 Testing equality of jobs.
(a) In general. What constitutes equal skill, equal effort, or equal responsibility cannot be precisely defined. In interpreting these key terms of the statute, the broad remedial purpose of the law must be taken into consideration. The terms constitute separate tests, each of which must be met in order for the equal pay standard to apply. It should be kept in mind that “equal” does not mean “identical.” Insubstantial or minor differences in the degree or amount of skill, or effort, or responsibility required for the performance of jobs will not render the equal pay standard inapplicable. On the other hand, substantial differences, such as those customarily associated with differences in wage levels when the jobs are performed by persons of one sex only, will ordinarily demonstrate an inequality as between the jobs justifying differences in pay. However, differences in skill, effort or responsibility which might be sufficient to justify a finding that two jobs are not equal within the meaning of the EPA if the greater skill, effort, or responsibility has been required of the higher paid sex, do not justify such a finding where the greater skill, effort, or responsibility is required of the lower paid sex. In determining whether job differences are so substantial as to make jobs unequal, it is pertinent to inquire whether and to what extent significance has been given to such differences in setting the wage levels for such jobs. Such an inquiry may, for example, disclose that apparent differences between jobs have not been recognized as relevant for wage purposes and that the facts as a whole support the conclusion that the differences are too insubstantial to prevent the jobs from being equal in all significant respects under the law.
