Editor's message: Under the Equality Act 2010, women and men who perform equal work have the right to claim equal pay with each other under their contracts of employment.
Equal work is defined as: like work; work rated as equivalent under a job evaluation scheme; or work of equal value. For example, workers employed by a supermarket chain to stack shelves might say that their work is like the work performed by workers employed to clean the supermarket.
While you do not have to carry out an equal pay audit, doing so is the best way for you to find out if you are paying men and women the same for equal work.

Gender pay and equal pay are frequently confused. However, there are key differences between the two and employers need to be aware of their obligations in relation to both.
Asda has lost an employment tribunal ruling in a case involving thousands of workers in supermarkets who sought to compare themselves with higher-paid men in distribution centres.
So much has been written about why women earn less than men and miss out on key promotions. But, as we prepare for gender pay gap reporting, are we ignoring the real reasons for gender inequality at work, asks Catalyst Europe's Allyson Zimmermann?
In Asda Stores Ltd v Brierley and others  IRLR 709 CA, the Court of Appeal held that, although employment tribunals have the power to grant an indefinite stay of proceedings, there was no requirement for a tribunal to do so merely because the respondent wanted to have equal pay claims against it heard in the High Court rather than the tribunal.
