Women earn less than their male counterparts for the same work, almost as soon as they enter the workforce.
The American Association of University Women Educational Foundation said one year after college, women are making only 80 percent of their male peers. And after 10 years, the study says the gap grows to 69 percent.
The foundation explained some of the difference on factors like hours, occupation and parenthood, but one-quarter of the pay gap remains unexplained. The foundation thinks that portion is sex discrimination.
