Uber's Chief People Officer Liane Hornsey has taken her last cab ride home from the office after she resigned following an investigation into her handling of complaints of racial discrimination. Reuters reported claims from whistleblowers that Hornsey had systematically dismissed complaints of racial discrimination at the company on Monday. By the end of Tuesday, she'd resigned. Chief Executive Dara Khosrowshahi praised Hornsey in an email to employees as “incredibly talented, creative, and hard-working” but gave no specific reason for her departure. Hornsey said in an email to her team at Uber that her exit “comes a little out of the blue for some of you, but I have been thinking about this for a while.” According to Reuters, the group of whistleblowers also allege Hornsey used discriminatory language and made derogatory comments about Uber Global Head of Diversity and Inclusion Bernard Coleman, and threatened former Uber executive Bozoma Saint John who left the company in June.
