National governments, voluntary initiatives by businesses, and actions by the European and national social partners have been undertaken to increase the participation of women in the labour market. This study tries to asses and evaluate some of these measures and their practical effects on women decision-making positions within middle and higher management. The study consists of two parts: first, a comparative study on legal and regulatory approaches in Europe to increase the share of women in middle and higher management positions, and second, five company cases from different countries.
