The survey, by consulting giant McKinsey and the Sheryl Sandberg-funded women's organization Lean In, shows a sharp divide between how men and women view their companies' efforts at advancing women. The annual report, which in 2017 surveyed more than 70,000 employees working at 76 companies, shows that 63 percent of men surveyed said their company is doing what it takes to improve gender diversity, while 49 percent of women said the same.
