The board of Uber was meeting Sunday to consider placing the CEO of the ride-hailing company on leave, according The New York Times and other news outlets.
The Times reported that three people with knowledge of the matter have confirmed that Uber's board was meeting to consider recommendations from a law firm hired to review Uber's corporate culture and that the board may decide to put CEO Travis Kalanick on temporary leave.
The newspaper says its sources requested anonymity because they were not authorized to speak for Uber.
Uber Technologies Inc. has been rocked by accusations that its management has fostered a workplace environment where harassment, discrimination and bullying are left unchecked.
Calls and emails to Uber spokesmen were not returned.
Reuters and the tech blog Recode reported the board meeting earlier. The Wall Street Journal also was citing unnamed sources about the meeting.
Uber has hired the law firm of former Attorney General Eric Holder to review policies and recommend changes. A report by his firm, Covington & Burling, was expected to be made public soon.
Uber announced last week that it fired 20 employees for harassment problems.
Under CEO Kalanick, Uber has shaken up the taxi industry in hundreds of cities and turned the San Francisco-based company into the world's most valuable startup. Uber's valuation has climbed to nearly $70 billion.
But Kalanick has acknowledged that his management style needs improvement. The 40-year-old CEO said earlier this year that he needed to "fundamentally change and grow up."
In February, former Uber engineer Susan Fowler wrote on a blog that she had been propositioned by her boss in a series of messages on her first day of work and that superiors ignored her complaints. Uber set up a hotline for complaints after that and hired the law firm of Perkins Coie to investigate.
That firm checked into 215 complaints, with 57 still under investigation.
In addition to firing 20 employees, Uber said Tuesday that it was hiring an Apple marketing executive, Bozoma Saint John, to help improve its tarnished brand. Saint John most recently was head of global consumer marketing for Apple Music and iTunes.
Uber has been plagued by more than sexual harassment complaints in recent months. It has been threatened by boycotts, sued and subject to a federal investigation that it used a fake version of its app to thwart authorities looking into whether it is breaking local laws.
