Even though women have been able to increase their participation in management positions to a small extent in recent years, they are still significantly underrepresented in management positions. Organisational measures to promote gender equality and work-life balance are seen as an option to reduce inequalities between men and women. However, there are relatively few firms that have formalised organisational gender equality policies. Against this background, I examine whether organisational measures may increase women's career opportunities or promote the assumption of management positions on a part-time basis. This is investigated using a German Linked-Employer-Employee dataset (LIAB) from 2012 to 2016 and logistic panel regression models.
