Women take on more ‘non-promotable work’ than men

Here’s a note from Bruno Navarro about this Fortune article:

Quite a shocking statistic, according to the authors of a new book, “The No Club: Putting a Stop to Women’s Dead-End Work”:

They found that women are 44% more likely to be asked by male managers to perform non-promotable tasks, and 50% more likely to say yes. Women and men have internalized a “shared expectation” that women will be the ones to take on these jobs. In a mixed-gender group, women volunteered to take meeting notes much more frequently than men; in single-gender groups, women and men volunteered at the same rate. “It’s not that men don’t know how to volunteer,” says Vesterlund. “They just don’t do it when women are in the group.” At one professional services firm, women took on 200 more hours of non-promotable work a year. That’s 200 hours those women didn’t spend on work that could advance their own careers.
