Uber boss Travis Kalanick plans to take time away from the company.
He revealed the decision in an email to employees on Tuesday.
The leave comes after an internal review of the firm's culture and practices, which was sparked by a former employee's claims the company ignored her complaints about sexual harassment and gender discrimination.
At a meeting on Sunday, Uber's board voted unanimously to adopt the recommendations in the report.
The email did not say how long Mr. Kalanick would be on leave.
Mr Kalanick's decision to step away is the latest sign of turmoil at Uber.
