Uber chief executive to take unspecified leave of absence
Uber chief executive Travis Kalanick will take a leave of absence for an unspecified period and let his leadership team run the troubled ride-hailing company while he is away.
Mr Kalanick told employees about his decision in a memo on Tuesday.
He says he needs time off to grieve for his mother, who died in a boating accident in May.
He also says he is responsible for the company's current situation and needs to become a better leader.
The announcement comes as former US attorney general Eric Holder released a list of recommendations to improve Uber's toxic culture.
Mr Holder's firm was hired to investigate Uber's workplace after a former engineer exposed rampant sexual harassment within Uber's ranks.
Mr Holder recommended that Mr Kalanick be relieved of some leadership responsibilities, shifting them to a chief operating officer and other senior managers.
The chief operating officer would be a partner with Mr Kalanick.
Mr Holder also recommended that Uber use performance reviews to hold senior managers accountable by setting metrics for improving diversity and responsiveness to employee complaints.
His firm, Covington & Burling LLP, and a second firm, Perkins Coie, were asked to conduct separate examinations of Uber's workplace culture after Susan Fowler posted a blog in February that detailed sexual harassment during the year she spent at Uber.
Ms Fowler wrote she was propositioned by her manager.
She reported him to human resources, but was told he would get a lecture but no further punishment because he was a "high performer", she wrote.
Mr Holder's investigators conducted more than 200 interviews with current and former employees, including people who had knowledge of Ms Fowler's allegations, according to the law firm's recommendations .
After Ms Fowler's blog, Uber Technologies Inc made changes in human resources and opened a 24-hour hotline for employees.
Last week, the company fired 20 people including some managers at the recommendation of Perkins Coie, which probed specific complaints made to the company about sex harassment, bullying, and retaliation for reporting problems.
That firm checked into 215 complaints, with 57 still under investigation.
Under Mr Kalanick, Uber has disrupted the taxi industry in hundreds of cities and turned the San Francisco-based company into the world's most valuable start-up.
Uber's valuation has climbed to nearly 70 billion US dollars (£55 billion).
