This document summarizes the findings of the 2020 Women in the Workplace report by McKinsey & Company and LeanIn.org, which surveyed over 40,000 employees from 317 companies. It finds that while there has been some progress for women in senior roles, the "broken rung" at the manager level remains. COVID-19 has exacerbated challenges like childcare responsibilities and burnout, particularly for women like mothers and senior-level women. It also highlights difficulties for groups like Black women. Companies are encouraged to offer more flexible work policies and support employee well-being and diversity to help address these issues.
