For the last two years, LeanIn.Org and SurveyMonkey have partnered to understand better what men and women are experiencing in the workplace in the #MeToo era in the US and UK.

60% of managers who are men in the US and 40% of managers who are men in the UK are uncomfortable participating in a common work activity with a woman, such as mentoring, working alone, or socializing together.1

Senior-level men are now far more hesitant to spend time with junior women than junior men across a range of basic work activities such as 1-on-1 meetings, travel, and work dinners.2

We need to actively support women at work, including by mentoring and sponsoring them. Men—who are the majority of managers and senior leaders—can help make this happen.
