A stunning 60% of male managers said they’re uncomfortable mentoring, working one-on-one, and socializing with women at work, according to a survey released Friday morning by LeanIn.org, the women’s advocacy group founded by Facebook executive Sheryl Sandberg.

That’s an increase from last year, when 46% of male managers said they were uneasy working with women after several prominent men lost their jobs over sexual misconduct claims.

In this year’s survey, men also said they were much more likely to hesitate to travel or have dinner with a junior woman for work.

It might seem like men avoiding women at the office is a fine solution to the problem of sexual harassment, but men still overwhelmingly hold positions of power at work. For better or worse, women need their support to get ahead. Notably, women are rarely asked if they’re afraid to interact with men ― even though they’re mainly the ones who’ve reported harassment and assault.

Even before Me Too, men were more likely to mentor or advise other men, said Rachel Thomas, president of LeanIn.org. Men were also more likely to “sponsor” more junior male employees ― meaning they talked them up to others, paving the way for promotion. Those cliches about men doing deals and schmoozing on the golf course exist for a reason.

That men are doing even less of this work in the wake of MeToo adds “insult to injury,” Thomas said. “If men want to be part of the solution, then pulling away from women is the wrong thing to do.”

Why exactly men are pulling back from women isn’t immediately clear from the data. Thirty-six percent of the men surveyed said they avoid mentoring or socializing with a woman because of how it could look to others. Others might feel a heightened awareness that their actions could make female colleagues uncomfortable.

Some men also like to claim that women are fabricating claims. Those fears are largely unfounded, Thomas said. She points out that the same myth surrounds sexual assault. False accusations make up a very low percentage of reported rapes, according to several studies — in line with other types of crime. When you factor in the percentage of sexual assaults that go unreported, the proportion of false reports goes down even more.

And considering the negative attention and career risks for women who speak up — I have spoken with dozens of women who’ve lost jobs, or have been blacklisted from entire industries, or even wind up homeless — the idea that women voluntarily make up harassment for personal gain seems even more preposterous.

In the wake of Me Too, men are simply afraid to interact with women at work, said John Singer, a lawyer who gained some attention for his work with men who’ve been fired for sexual misconduct. His firm also represents women in sexual harassment cases.

“MeToo has had a chilling effect on the relationship between men and women in the workplace. Men are either scared to be alone with female colleagues or clients or more skittish about what to say,” he said, adding that male and female clients both have told him that women are getting excluded from meetings and social outings.

That isolation isn’t just keeping women from moving up ― but making it harder for them to simply do their jobs, meeting with clients or teaming up on sales calls, he said.
