In 2001, more than thirty years after the passage of Title VII of the Civil Rights Act, women still have not achieved equality in the workplace. Many statistics emphasize the divide: Last year, 95% of all venture capital went to men; of the top 2,500 corporate executives in America, only sixty-three are women; only three Fortune 500 companies are headed by women; and Congress is 90% male.

While many factors undoubtedly contribute to this disparity, one factor in particular stands out: Women are more likely to take family leave after the birth or adoption of a child, and are far more likely to serve as the primary caregiver for children.
