After weeks of mounting anticipation, Uber Technologies Inc. Tuesday released a 13-page report by former U.S. Attorney General Eric Holder and lawyers at Covington & Burling LLP about how the ride-hailing company should address complaints about sexual harassment, a lack of diversity and other workplace issues. 

For starters, Holder suggested that the board review CEO Travis Kalanick's responsibilities, and consider giving some of them to other members of senior management. On Tuesday, CEO Travis Kalanick announced in an email to employees that he would be taking an indefinite leave of absence from the company to mourn his recently-deceased mother and that his direct reports would run the company while he was away.

The Holder report also recommended Uber should also enact something akin to the National Football League's "Rooney Rule," which requires teams to interview minorities for head coach vacancies (the rule is named after longtime Pittsburgh Steeler's owner Dan Rooney, who championed more diverse hiring in the NFL).

"Uber should utilize the Rooney Rule for women and other underrepresented populations for key positions, wherein each pool of candidates interviewed for each identified position includes at least one woman and one member of an underrepresented minority group, thereby ensuring that members of the populations currently underrepresented in Uber's workplace are interviewed with appropriate consistency," the report states.

Senior leaders should also receive performance reviews based on how well they respond to employee complaints, establish a diverse workforce and meet other goals. Uber should also modify its board by adding independent directors and an independent Chairperson, Holder suggested.

The company should also provide "inclusive leadership" training for senior managers and strengthen its complaint review processes, among other recommendations.
