"The benefits aren’t limited to salaries, either. Workers in unions are much more likely to get employer benefits like pensions and health care. And this is also particularly true for women and people of color. About three-quarters of unionized women have a pension, compared to 42 percent of non-union female workers, and more than three-quarters have health insurance coverage through work versus about half of non-unionized women. Unionized black and Hispanic workers are between 27 and 30 percent more likely to have those benefits."
