245.This section deals with sex discrimination in relation to contractual pay in circumstances where a sex equality clause would not operate. This could be because there is no comparator doing equal work with whom a claimant can compare his or her pay or other terms. The section ensures that indirect sex discrimination in respect of contractual pay can be challenged only by means of an equality clause. However, the section for the first time enables a person who is treated less favourably than others by being paid less because of the person’s sex or a combination of two protected characteristics including sex to pursue a claim for direct or dual discrimination where an equality clause does not operate.
