2. The company is re-writing its cultural values to get rid of aggressive phrases like 'principled confrontation'

Part of Uber's aggressive culture has been baked into the way Kalanick and Jeff Holden, the company's chief product officer, defined its core principles. Among those 14 values were items like "Always Be Hustlin", "toe-stepping", and "principled confrontation" that encourage employees to work long hours and challenge each other's work.

Now, though, "our values must be inclusive and focus on teamwork, collaboration and joy at work, and remove aggressive individual behaviors," Uber's HR chief Liane Hornsey wrote in an email to employees.
