We need women at all levels, including the top, to change the dynamic, reshape the conversation, to make sure women’s voices are heard and heeded, not overlooked and ignored.

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.

The gender stereotypes introduced in childhood are reinforced throughout our lives and become self-fulfilling prophesies. Most leadership positions are held by men, so women don't expect to achieve them, and that becomes one of the reasons they don't.

But I really believe that when you give people authentic identity, which is what Facebook does, and you can be your real self and connect with real people online, things will change.

If more women are in leadership roles, we'll stop assuming they shouldn't be.

we compromise our career goals to make room for partners and children who may not even exist yet
