Equal pay legislation has been around since the 1970s, giving men and women the right to claim equal pay where they perform "equal work". It is unlawful to pay people unequally because they are a man or a woman. The gender pay gap shows the difference in the average pay between all men and women in a workforce. If a workforce has a particularly high gender pay gap, this can indicate there may be a number of issues to deal with, and the individual calculations may help to identify what those issues are. There are a variety of factors behind it, including the impact on women's career progression of taking time out of the labour market to have children, and career choices, with typical “male” subjects such as IT and science often leading to higherpaid roles. To address the issue, the Government has introduced a requirement for all large organisations to publish their gender pay gap, ours can be viewed in the report below.
