McKinsey's 2015 Women in the Workplace report reveals from entry level to the C-suite, women are underrepresented at US corporations, less likely to advance than men, and face more barriers to senior leadership. In fact, at the rate of progress of the past three years, it will take more than 100 years for the upper reaches of US corporations to achieve gender parity. The research finds that for numerous reasons, women are simply less likely than men to advance: they experience an uneven playing field, with their odds of advancement lower at every level; there is a persistent leadership gap in the most senior roles; gender diversity is not widely believed to be a priority; and while employee programmes designed to help balance work and family are abundant, participation is low among both sexes due to concerns that using them will negatively affect their careers.
