As some people may already know, all UK companies with over 250 employees have to report on the gender pay gap at their companies.
It is illegal to pay someone less than another person for the same work because of gender, race, religion etc. Largely these types of gaps come from different job roles and different amounts of experience.
Where I work, we have performance related pay rises, as do many other companies. If we have two employees (A & B), who both join the company from uni, with the same degree into the same job role, but A is generally seen as more productive than B, then A will get a better pay rise. They are still technically doing the same job, with the same title, but A earns more money.
This seems like a fair system assuming the way their performance is rated is accurate. But does this count as pay discrimination if A & B are different genders? Or is this system ok because the company can point to the performance reviews of each employee as evidence of why one is earning more than the other?
