Uber CEO Travis Kalanick is taking a leave of absence from the company.
After months of interviewing employees and workplace reviews, Uber has released the recommendations of an internal investigation about its failings to police reckless behavior within the company.
The investigation, led by former U.S. Attorney General Eric Holder, began in February after an ex-Uber engineer published a blog post in which she said she had repeatedly complained about sexual harassment and discrimination at the ride-hailing company.
In a 13-page document, Holder outlined his recommendations under four overarching themes: tone at the top, trust, transformation, and accountability. Holder recommended that the company:
- Review and reallocate Travis Kalanick’s responsibilities. “The search for a Chief Operating Officer should address this concern to some extent,” the report reads. The COO is to act as a full partner to Kalanick.
- Adopt a zero-tolerance policy for substantiated complaints of discrimination and harassment, without regard to whether an employee is a “high performer” or a long-term employee.
- Elevate the visibility of Uber’s current head of diversity in order to demonstrate the company’s commitment to the issue. The company should also consider adding an employee diversity advisory board.
- Regularly publish diversity statistics to judge how the company is meeting its goals.
- Use performance reviews to hold senior leaders accountable. The reviews should include metrics tied to improving diversity, responsiveness to employee complaints, employee satisfaction, and compliance.
- Restructure the board to include additional independent board seats who can exercise oversight of Uber’s management.
- Require senior leaders at Uber to receive mandatory leadership coaching. Holder also recommended that new or first-time managers receive significant training.
- Target diverse sources of talent, use blind resume review, and adopt a version of the “Rooney Rule.” [Read Fortune’s explainer on the Rooney Rule here]
- Develop clear guidance on appropriate workplace relationships, including making clear that any type of romantic or intimate relationship between individuals in a reporting relationship is prohibited.
- Audit and review its pay practices, including for compliance with state and federal equal pay laws.
The results were discussed on during a six-hour meeting on Sunday with the tech giant’s board, which unanimously voted to adopt all of Holder’s recommendations. Uber board member Arianna Huffington said in March, “Whatever the investigation finds will be honored by everyone at Uber.”

In an internal memo to staff, Kalanick announced that he would take a leave of absence from the company following a boating accident last month in which his mother died and his father was injured. He did not specify for how long he would be away from Uber, but he added that he needed to “take some time off the day-to-day to grieve my mother” and to “reflect, to work on myself, and to focus on building out a world-class leadership team.” Here is the full email:
Here are some key developments during the weeks leading up to the release of the investigation results:
- Emil Michael, senior vice president and a close Kalanick ally, has left the company.
- More than 20 employees were terminated as a result of the internal investigation. The company cited sexual harassment and an array of other behaviors, such as bullying and retaliation, as reasons for the firings.
- Eric Alexander, Uber’s president of business in the Asia-Pacific region, was fired after it was learned that he obtained the medical records of an Uber passenger who was raped by her driver in India three years ago. Alexander reportedly showed the passenger’s medical records to Uber CEO Travis Kalanick, senior vice president Emil Michael, and other executives.
- Uber hired Frances Frei, a professor and an associate dean at Harvard Business School, as its first senior vice president of leadership and strategy.
