In a February blog post titled, " Reflecting on one very, very strange year at Uber ," former Uber engineer Susan Fowler shared her experience of workplace discrimination, routine harassment, and how her complaints were ignored by the company. Fowler's blog post prompted Uber's former CEO Travis Kalanick to order two independent investigations into the company's culture and harassment allegations. The result led to an outline of changes at the ridesharing company, a number of firings - and ultimately led to the board pressuring Kalanick to resign.
