Uber's board of directors is meeting Sunday in Los Angeles to discuss the possible firings or forced resignations of some of its high-level executives in the wake of the results of a months-long investigation into sexual harassment claims at the company led by former U.S. Attorney General Eric Holder. It was reported that Michael was planning to resign from Uber as early as Monday, although sources close to him say that he has not yet made his decision and is weighing his options for the future.
Uber CEO Travis Kalanick was advised not to send the 2013 email, known as the "Miami letter".
Alexander then brought the files to Kalanick and Michael, who read them, the report said, adding that soon all three began to consider the prospect whether Uber's main rival in India, Ola, was behind the incident to sabotage the company.
Both Uber and Mr Kalanick have declined to comment.
The investigation into company culture, performed by Holder's law firm, Perkins Coie LLP, was called for by Kalanick after a blog post by engineer Susan Fowler described a soul-crushing experience where her manager wanted to have sex with her, and when she reported the situation to HR, it was essentially ignored because her manager was a "high performer".
The board, according to a person briefed on the matter, said they will discuss Kalanick taking time off from the company.
In a statement to CNN Tech, Huffington said her involvement at Uber will decrease now that the investigation has wrapped up. The 40-year-old executive was captured on video in February berating an Uber driver.
Other than Kalanick, the most powerful executives at Uber include Emil Michael, a close associate of Kalanick who has been with the company for almost four years; Rachel Holt, who leads Uber's North American business; and Graves, who was Uber's first chief executive and who has been with the company from the start. He said his "beliefs and approach to leadership" were "inconsistent" with those of the company.
According to sources speaking with the New York Times, the question of whether Kalanick should take a leave of absense rests in the hands of Garrett Camp, Uber's chairman, and board member Ryan Graves.
Kalanick is also facing a personal trauma: Last month his mother died in a boating accident, which also badly injured his father.
