Any figures advanced to sustain a case that extensive rate discrimination exists, are likely to be misleading because they cannot represent the full extent to which the principle of equal pay for equal work exists throughout industry. While contract provisions might show the degree to which equal pay is embodied in collective bargaining agreements, they fail to indicate the far greater number of cases where employers of their own volition paid the same rates to men and women where jobs were equal, or where an identical wage scale is applicable to men and women although no specific ‘equal wage’ provision is contained in the agreement.
