Uber also released the recommendations of a months-long investigation led by the law firm of former U.S. Attorney General Eric Holder who was retained by Uber to look into company culture and practices.
The recommendations, which were unanimously adopted by the board on Sunday, call for reducing Kalanick's sweeping authority and instituting more controls over spending, human resources and the behavior of managers.
Specifically, the recommendations call for adding independent members to the board of directors, including an independent chair. They also spell out changes to company culture, including prohibiting romances between bosses and their reports and creating clearer guidelines around use of drugs and alcohol.
Kalanick's leave of absence follows a day-long board meeting on Sunday during which members of Uber's board of directors discussed the possibility of Kalanick temporarily stepping away from the company.
"If we are going to work on Uber 2.0, I also need to work on Travis 2.0 to become the leader that this company needs and that you deserve," Kalanick wrote in his email.
