Much of the report's advice addressed a history of sexist behavior at Uber, but that didn't stop board member David Bonderman - a founder of the TPG Capital investment group - from making a stupid, sexist comment during the meeting.
"Today at Uber's all-hands meeting, I directed a comment to my colleague and friend Arianna Huffington that was careless, inappropriate, and inexcusable", Bonderman said in a statement.
His leave of absence coincides with the release of recommendations from former Attorney General Eric Holder's investigation into the company's workplace culture.
Earlier this week, Uber appointed Nestlé executive Wan Ling Martello to the board.
"We have been joined on the board by an incredible leader who also happens to be a woman", Huffington said in front of an audience of most of Uber's staff.

In an email that was sent later to company employees, Bonderman said: "I want to apologize to my fellow board member for a disrespectful comment" that he called "inappropriate".
Apparently, fellow board member Ariana Huffington was talking about the benefits of adding more women to Uber's board, at which point Bonderman interrupted her to say that having more women around would make it "much more likely there'll be more talking". The company has been working to improve its image and internal procedures, but in a meeting on Tuesday, one Uber board member said that women talk too much, creating yet another mess for a company that has been publicly battling accusations of toxic misogyny within its highest ranks.
Bonderman's remark created uproar at a time when the company is trying to fix its image after allegations of sexual harassment, workplace misconduct and leadership issues. "I deeply regret it".
