One of the most visible, tangible and pervasive manifestations of discrimination is that women across the globe are still being paid less than men for work of equal value. That is why this equal pay initiative was developed and why it is a focus area of the ILO’s Women at Work Centenary Initiative. The principle of equal pay for work of equal value is enshrined in the ILO Constitution of 1919. One hundred years is too long to wait, and we must all work together to make equal pay for work of equal value a reality.
