Uber's board has unanimously agreed to all of the company's culture fixes

Uber took a step towards reforming its culture after the company's board agreed on Sunday to approve all the recommendations stemming from an external investigation into harassment and other bad behavior in Uber's workplace.

What exactly the board agreed to - and the fate of its CEO Travis Kalanick - remains a secret until the recommendations are shared with employees on Tuesday.

"The Uber Board met today with Eric Holder and Tammy Albarrán," an Uber board spokesperson. "The Board unanimously voted to adopt all the recommendations of the Holder Report. The recommendations will be released to the employees on Tuesday."

The Holder Report is the culmination of a several-month investigation into Uber's workplace. The company hired former US attorney general Eric Holder in February after an ex-engineer penned a blog post about the "strange" year she experienced while at Uber. Her blog post included accusations of sexual harassment and gender discrimination throughout the company.

An additional investigation, lead by a separate law firm, resulted in the firing of more than 20 Uber employees after the firm received 215 claims of sexual harassment and other bad behaviors at the company.

Holder's report is based in part on those 215 claims. The recommendations he's made as a result, which will not be made public until Tuesday, are expected by people close to the company to not only be wide-ranging cultural reforms, but may also include personnel recommendations.

The board debated for seven hours on Sunday at the Los Angeles offices of Covington & Burling, Holder's law firm. Prior to the board meeting the Wall Street Journal reported that Emil Michael, Uber's long-standing Chief Business Officer who has been linked to several of the scandals, may resign as early as Monday as a result of the report.

The biggest unanswered question remains the future of Kalanick as CEO of the company. Reuters first reported that the board was going to discuss whether or not the embattled CEO, who is also facing a personal tragedy after the loss of mother, should take a three-month leave of absence. Uber's board did not comment on Kalanick's future at the company. An Uber spokeswoman also declined to comment further.
