In a recent Gallup poll, 15 percent of American women said that they have been passed over for a promotion or an opportunity at work because of their gender. Thirteen percent reported having been denied a raise for the same reason.

This is a problem disproportionately affecting women. When Gallup asked men these questions, just 8 percent said they were denied a promotion because of their gender and a mere 4 percent reported being denied a raise for that reason.

Women also report being less satisfied with their pay and promotions.
