The Uber exec and board member who oversaw the HR department has been strangely absent during Uber's biggest crisis

As a sexism scandal rocks Uber, its CEO Travis Kalanick has been on the defensive, holding all-hands meetings with the company and sitting down with the women in its engineering group to hear their complaints.

Yet there's one person at the center of it all who has remained conspicuously missing: Uber's first CEO, current board member, and its head of operations, Ryan Graves.

Graves has apparently "vanished from the office, hasn't been seen or heard from in days," one Uber insider told Business Insider. Other people inside Uber confirmed that Graves hasn't displayed the leadership they would have expected during such a challenging period, but note that he has resurfaced in the office briefly in the last few days after much time away.

It's a marked absence given that the human resources department reported to Graves directly, not Kalanick, until a couple of months ago. Uber and its HR department are under fire, after a former Uber engineer alleged that it ignored employees' sexual harassment claims.

Now that the company is facing an investigation into possible systemic problems of sexual harassment at the company, Graves' absence is leading some inside and outside the company to believe he's the one about to take the fall — with or without cause.

"I wouldn't be surprised," said a former employee who worked closely with Graves, noting that ousting him would be a largely "ceremonial" move in response to the mounting pressure.

Graves did not respond to requests for comment. An Uber spokesperson declined to comment on Graves' recent whereabouts or this story.

Superpumped

Graves is a well-liked figure within Uber and has been central to the ride-hailing company's rapid transformation into a $69 billion powerhouse during the past seven years.

After serving a brief stint as Uber's first CEO from 2010 to 2011, Graves handed the reins to Kalanick and eventually assumed the role of
Uber's president and VP of operations. That meant overseeing Uber's "People Operations" team, which was led by Renee Atwood.

The ex Uber employee said that Graves, a former business development intern at Foursquare who attended GE's management training program, did not have the experience for such an important role at a growing company with thousands of employees and hundreds of millions of dollars in revenue.

The allegations by former Uber engineer Susan Fowler do not provide exact dates and names, and Graves' involvement in handling the various incidents she alleges is also unclear.
