We have had several young men start out as secretaries and later rise to positions of importance. …When these young men started, and as they progressed, I am certain that their wages were higher than some female secretaries doing equal or superior work. But we also knew that there was a possible potential of their rising to more important jobs, supervising a large number of men. If this law is passed, we will hire women for all secretarial positions and be deprived of this avenue of advancement.
From the written testimony of William Miller representative of the U.S. Chamber of Commerce at the House hearing “Equal Pay Act”.
