When I was pregnant, I joined an antenatal group of eight women in south London who worked across a broad spectrum of careers. Two years on, only half of us work – stress and discrimination has driven the others from their jobs...For some of the mothers in my group, the problems started before their babies even arrived...Even those who were not forced out of work have struggled...Workplace obstacles for both pregnant women and those returning to work after maternity leave appear to be growing across all industries, and many barriers stand in the way of women who want to work, but also have a family.
