Currently, the ride-hailing company is in the process of recruiting a second-in-command who can work alongside Kalanick, the CEO who has turned Uber into one of Silicon Valley's most successful companies but who has also become a magnet for criticism because of the win-at-all-costs culture he has fostered.
Some of those structures include new training for Uber's managers, 61 percent of whom have had no prior managerial experience, Huffington said.
Huffington said Kalanick is honest that he wants the incoming COO to be a true partner with him. Asked if the board would seek Kalanick's ouster if the inquiry finds he had knowledge of the harassment, Huffington said "this hasn't come up, and we don't expect it to come up".
"Many of you have been asking what qualities we're looking for in a COO", Huffington said in her introduction to the call. The ultimate judgment of whether issues such as sexism and lack of diversity are "systemic problems", she said, would be revealed through an investigation led by former Attorney General Eric Holder. He said that it was a tough decision to make however he doesn't see any future for him with the company.

"The focus of the company has been on the business and not the employees", she told reporters.
Liane Hornsey, Uber's new head of human resources, said more than 100 "listening sessions" had taken place across the company.
This leaves Uber in the "fortunate position" of being able to tackle its needed changes while the "business remains healthy", according to Holt.
