Female professionals share several challenges in today’s workplace, such as career advancement, re-entering the workforce and sexual harassment, to name a few. But according to a recent Korn Ferry survey, 40 percent of women professionals said they’ve missed a promotion or an opportunity simply because they’re female.

What’s more, the most important issue facing women in the American workplace is the pay gap, with 42 percent of respondents selecting that over gender discrimination (26 percent), glass ceiling (25 percent) and sexual harassment (7 percent).
