…the Secretary of Labor becomes prosecutor, judge, and legislator. He is given extensive authority to intervene and interfere in employer-employee relations. He must build a considerable Federal division of his Department to accomplish this purpose at increased cost to the taxpayers….Further, the Secretary is not required to await the complaint of an aggrieved employee. He is empowered to prevent any person from engaging in the prohibited wage discrimination. He may proceed on his own motion. There is not limit to the interference with efficient operations or the amount of snooping which may result in an effort to uncover evidence concerning existing or possible future wage discrimination.
From the Prepared Statement of the National Association of Manufacturers at the Senate Committee on Labor and public Welfare (Subcommittee on Labor) hearing “Equal Pay Act of 1962.”
