There is much concern about why women are not making it to the top of organisations and professions. Equal numbers of men and women are recruited and a reasonable percentage are there at mid to senior levels, but there are few at the top.

When asked why this happens, I say with some confidence that it is about workplace culture. Two years ago we surveyed all our alumnae from Murray Edwards College, Cambridge. When asked what had been the biggest challenge to their career, 22 per cent of those women said it was combining work and family; 38 per cent cited an unsupportive workplace culture.

This is not all about gender bias, but a lot was summed up by a woman in her mid-30s: “I was surprised by how male-dominated the workplace is, designed by men, for men, with a male culture and set of values.”
