The CEO said he instructed Liane Hornsey, Uber's recently hired chief human resources officer, to "conduct an urgent investigation into these allegations." Arianna Huffington, who is on Uber's board, said she would work with Hornsey on the investigation.
Fowler didn't immediately respond to a message to a Twitter account that appeared to be hers, or an e-mail to the address listed on her website. She said she left Uber in December after a "strange year," and is now working at Stripe Inc., a payments startup.
In her account, Fowler said that she had heard similar stories from other women at Uber, and that some of them involved the same manager. She accused Uber's human resources department of failing to act on such reports and for blocking any opportunities for advancement.
"I feel a lot of sadness, but I can't help but laugh at how ridiculous everything was," Fowler wrote. "Such a strange experience."
This incident comes after Uber just weathered another public relations disaster. The company faced allegations that it helped break a New York taxi union strike that was protesting President Donald Trump's refugee ban. The hashtag #deleteuber trended on Twitter and ultimately Kalanick left a board advising President Trump in an attempt to quiet the backlash. The hashtag resurfaced after Fowler made her post.
