Yet the focus on pushing for the best result has also fueled what current and former Uber employees describe as a Hobbesian environment at the company, in which workers are sometimes pitted against one another and where a blind eye is turned to infractions from top performers.
Among the most egregious accusations from employees, who either witnessed or were subject to incidents and who asked to remain anonymous because of confidentiality agreements and fear of retaliation: One Uber manager groped female co-workers’ breasts at a company retreat in Las Vegas. A director shouted a homophobic slur at a subordinate during a heated confrontation in a meeting. Another manager threatened to beat an underperforming employee’s head in with a baseball bat.
Then on Sunday, Susan Fowler, an engineer who left Uber in December, published a blog post about her time at the company. She detailed a history of discrimination and sexual harassment by her managers, which she said was shrugged off by Uber’s human resources department. Ms. Fowler said the culture was stoked — and even fostered — by those at the top of the company.
Her revelations have spurred hand-wringing over how unfriendly Silicon Valley workplaces can be to women and provoked an internal crisis at Uber. The company’s chief executive, Travis Kalanick, has opened an internal investigation into the accusations and has brought in the board member Arianna Huffington and the former attorney general Eric H. Holder Jr. to look into harassment issues and the human resources department.
“What I can promise you is that I will get better every day,” he said. “I can tell you that I am authentically and fully dedicated to getting to the bottom of this.”
Mr. Kalanick, 40, has made pointed displays of ego: In a GQ article in 2014, he referred to Uber as “Boob-er” because of how the company helped him attract women.
One group appeared immune to internal scrutiny, the current and former employees said. Members of the group, called the A-Team and composed of executives who were personally close to Mr. Kalanick, were shielded from much accountability over their actions.
Uber’s aggressive workplace culture spilled out at a global all-hands meeting in late 2015 in Las Vegas, where the company hired Beyoncé to perform at the rooftop bar of the Palms Hotel. Between bouts of drinking and gambling, Uber employees used cocaine in the bathrooms at private parties, said three attendees, and a manager groped several female employees. (The manager was terminated within 12 hours.) One employee hijacked a private shuttle bus, filled it with friends and took it for a joy ride, the attendees said.
According to attendees and video of the meeting, Ms. Huffington said there would no longer be hiring of “brilliant jerks.”
