The article examines whether ethnic minority employees report poorer treatment at work than white employees, and evaluates the impact of three key features — gender differences, formal equal opportunities policies and trade union recognition. The analysis reveals that ethnic minority men and women receive poorer treatment than their white counterparts. In addition, there is evidence to suggest that ethnic minority women receive poorer treatment than ethnic minority men. Equal opportunities policies are effective in ensuring equal treatment, but the presence of a recognised trade union is not. White men and women in unionised workplaces enjoy better treatment than their white counterparts in non-union workplaces, but the same is not true for ethnic minorities. By contrast, there is very little evidence of unequal treatment in non-union workplaces.
