Businesses guilty of discrimination may be liable for prosecution. But what does the law say? Under the Equality Act 2010, it is illegal to discriminate against people on grounds of what are known as "protected characteristics". These include race, sex, age, disability.

This is when an employer discriminates against someone because they think the employee possesses a protected characteristic - even though they may not actually have it.
