A majority of job seekers, 67%, say that a diverse workforce is important when evaluating a company or job offer, according to a Glassdoor diversity hiring survey.

Yet, just 33 companies on the Fortune 500 have a woman CEO. That's an increase from last year's total of 24, but it signals that corporate America still has a long way to go in its efforts to hire and promote more women.

Looking at the roughly 900,000 employers on its platform, Glassdoor analyzed which CEOs received the best approval ratings from its staff. Out of the 100 CEOs ranked in the U.S., seven women made the cut.
