What does the following brief mean

Question

The law requires employers to pay men and women equal pay for equal work unless employers can demonstrate that the pay disparity between employees of different genders is fair and nondiscriminatory. An exception is when an employee is paid for “additional duties” that lower paid workers don’t perform.

Answer 1

This brief means that the law mandates that employers must pay male and female employees the same amount for the same work, unless they can provide valid reasons for pay disparities that are not based on gender discrimination. One exception is when an employee is paid more for additional duties that lower-paid workers do not perform.
