I believe we need affordable child care. I believe we need flexibility. I believe we need institutional reform and public policy reform.

I'd worked on leprosy and malaria in India [at the World Bank] and asked myself the question: Why do we let 2 million children die every year around the world for not having clean water? Because they're faceless and nameless. So, for me, Facebook looked like it was going to solve the problem of the invisible victim.

It's more pressure on women to - if they marry or partner with someone, to partner with the right person. Because you cannot have a full career and a full life at home with your children if you are also doing all of the housework and child care.

Women systematically underestimate their own abilities.

It is illegal to discriminate on the basis of pregnancy or gender. It is not illegal to talk about it.

I was grateful that Facebook already had generous bereavement policies . Now Facebook employees receive 20 days paid leave to grieve the loss of an immediate family member and 10 days for an extended family member. I'm proud that we're able to do this and I hope more businesses do the same. Only 60 percent of private sector workers get paid time off after the death of a loved one, and then it's usually just a few days. Workers and families deserve better than that.

Facebook is great for women and men. We are enormously flexible. We care a lot about great opportunities for women, we push ourselves to make things as flexible as possible.
