On 1 September 2003 the EOC launched a General Formal Investigation...into the discrimination faced by pregnant women at work. This Review is part of the initial stage of the investigation. Conducted between July and September 2003, it highlights the information and data available regarding the scope, nature and impact of pregnancy discrimination in the UK, concentrating on legal issues. It includes a comparison of the legal provisions available to pregnant workers in France and Sweden, and suggests possible avenues for research.
