Sandberg has no plans to leave Facebook for Uber

Kalanick's penchant for conflict undermined the company's prospects, said Ferdinand Dudenhoeffer, director of the Center for Automotive Research at the University of Duisburg-Essen.

"I love Uber more than anything in the world and at this hard moment in my personal life I have accepted the investors' request to step aside so that Uber can go back to building rather than be distracted with another fight", Kalanick said in a statement, quoted by The Times and confirmed by Uber.

BravoSolution and the North Carolina State's Supply Chain Resource released Tuesday the results of their first annual Procurement Data Governance Survey, according to a press release.

But that brashness has also been blamed for scandals this year, from the unearthing of a culture of bullying and discrimination at Uber to a US Department of Justice federal investigation and a high-stakes lawsuit filed by Alphabet Inc that threatens Uber's self-driving vehicle ambitions.

"Sheryl is seen is exactly what this company needs right now", a source told the Post.

Kalanick joined the company as CEO in December 2010, about seven months after it launched.

The CEO search is now the board's leading priority, taking precedence over the company's previous hunt for a chief operating officer who was supposed to act as a "full partner" to Kalanick.

Ultimately, it was some of Uber's main investors who forced Kalanick out, according to a source familiar with the matter.

McWhorter said Uber's use of contract drivers provides the kind of flexibility she wants women workers to have, but said she "firmly believes" the change in leadership is an opportunity for Uber to address its cultural issues and build a better company.

Uber has also been searching for a COO for months to help Kalanick.

Travis Kalanick, Uber's co-founder and primary visionary, is out as CEO.

"I think it was needed, I think it was right thing to do", he said, after getting his auto checked out at Uber's driver hub on Chicago's Near North Side later that day.

In the wake of Fowler's claims, Uber hired former Attorney General Eric Holder to undertake an investigation into Uber's work culture.

Uber's current troubles stem from the fact that it let its employees and its drivers down.

Uber launched its ride-sharing service in Pittsburgh in early 2014.

On June 13, Kalanick went on indefinite leave amid criticism of his management style and following the death of his mother in a boating accident. Kalanick's departure may make it easier for Uber to attract high-quality executives.

At this point, who runs Uber in the longer-term may be anyone's guess. Uber insiders may also be considered, including board member Arianna Huffington.

Kalanick has enjoyed sweeping power at Uber, through his share ownership and voting power, as well as his commanding personality and micromanaging tendencies.

Kalanick, who grew Uber's bookings to $20 billion past year, has played a starring role in most of its controversies.

Kalanick's resignation comes as a surprise to employees and people close to the company.
