The Uber board of directors is slated to meet Sunday to discuss the possible leave of absence of co-founder and CEO Travis Kalanick, other management changes and what is described as an ugly or bombshell report about a rash of sexual harassment incidents at the company and its culture, according to multiple published reports.

The report, conducted by former U.S. attorney general Eric Holder, has already been distributed to the board, Recode reports, and it follows the termination of dozens of Uber employees and the disciplining of others for incidents related to sexual harassment charges in recent months.

Meanwhile, in a harbinger of other changes, the Wall Street Journal reported Sunday afternoon that Uber chief business officer Emil Michael was expected to resign as soon as Monday.

There have been a series of problems over the last year or more that have called Kalanick’s leadership of the ride-share company into question. One of the latest that Holder’s report uncovered, according to The New York Times, is that the head of Uber Asia, a close Kalanick associate who was fired this week, shared medical records of a rape victim in India with Kalanick and other Uber executives.

An Uber driver in India had been convicted of raping the woman in 2015, but Uber’s boss in Asia, Eric Alexander, and other Uber executives became convinced that the driver was set up, and so Alexander retrieved and shared her personal medical records.

It isn’t clear what the details of Holder’s report will contain or what actions the Uber board might take today, but the moment is shaping up as a critical one for Uber’s future.
