Uber’s Messy Breakup Complicates Search for COO

During his brief tenure as Uber Technologies Inc.’s president, Jeff Jones toured far-flung offices in India, the Netherlands and other key markets for the global ride-hailing giant. In meetings with local staff, Jones professed that one of his biggest apprehensions was working with Chief Executive Officer Travis Kalanick, according to a person familiar with the gatherings.

Six months after joining Uber, his misgivings were apparently confirmed. Jones, the most senior member of Kalanick’s executive team, resigned as president of ride sharing on Sunday. He joins three other senior executives who have left in the last month as the company grapples with a long succession of scandals. Without naming his boss, Jones chastised Uber management: “The beliefs and approach to leadership that have guided my career are inconsistent with what I saw and experienced at Uber,” he wrote in an email.
