Sex discrimination occurs when someone is treated unfairly for reasons relating to their sex. Although illegal in the UK for many years, the law is now incorporated into the Equality Act 2010. Sex discrimination continues to be an issue, for example, sexual and sex-based harassment and the related area of pregnancy and maternity discrimination remain serious problems, and low numbers of women in senior roles is a key challenge for many organisations.
