Just anecdotally, I don’t think a man sending a “do x or I’ll quit” email would be met with the same response. I think issues of race and gender are playing a role here, and that’s a shame, because while firing (accepting this resignation) of this researcher might make short term business sense, it seems like it does harm to Google’s long term credibility in trying to engage with reducing the barriers faced by (among others) women and people of color.
It’s a shame there wasn’t a pathway to keeping the dialogue going, for example by getting in touch with her and letting her know that some things she was asking for wouldn’t work, but that you could work with her to accomplish her goals in some other way.
From my privileged outside point of view, that seems like it could have been a more humane response which could have disarmed the conflict. I think opportunities to pursue options like that are de-emphasized when management are put in an all or nothing position.
A missed opportunity for leadership.
