Don\u2019t retire your #DeleteUber hashtag just yet. In a blog post dated February 19, Susan Fowler, who joined Uber as a systems reliability engineer in 2015, recounts her repeated attempts to report inappropriate conduct by a manager -- only to be brushed off, ignored, threatened and denied transfers.\nIn the post, titled "Reflecting On One Very, Very Strange Year At Uber," Fowler alleges that during her first couple weeks at the San Francisco-based tech firm her team manager propositioned her for sex. \u201cI immediately took screenshots of these chat messages and reported him to HR. Upper management told me that he 'was a high performer' (i.e. had stellar performance reviews from his superiors) and they wouldn't feel comfortable punishing him for what was probably just an innocent mistake on his part.\u201d\nThis is surprising only to those who haven\u2019t been paying attention. Also not surprising is that it\u2019s only after Fowler\u2019s story went viral that Uber finally decided to look into the allegations.\nAgain, the careers of \u201chigh performing\u201d white, straight males are prioritized over those of the targets of their harassment. I have to wonder if had CEO Travis Kalanick not been so recently skewered for his participation on a certain Business Advisory Board he\u2019d be taking the same stance. Because this issue certainly goes deeper than just one or a few managers at the company. It speaks to much deeper cultural issues within Uber\u2019s HR department. And that begs the question: What did Kalanick know, and when did he know it?\nThough his Tweets about the revelations certainly sound the right notes. Kalanick\u00a0said\u00a0that what Fowler experienced "is abhorrent and against everything we believe in. Anyone who behaves this way or thinks this is OK will be fired." And, in a second Tweet,\u00a0he added: "I've instructed our [chief human resources officer] CHRO Liane [Hornsey] to conduct an urgent investigation. There can be absolutely no place for this kind of behavior at Uber."\nIt\u2019s puzzling that he wasn\u2019t aware of these issues until Fowler\u2019s blog post brought them to his attention. What kind of culture do you have when your HR department and other organizations aren\u2019t bringing these things to your attention as they\u2019re happening?\nLiane Hornsey -- who just joined Uber as CHRO in January following Renee Atwood\u2019s move to Twitter ( maybe Jack Dorsey should keep an extra close eye on his new executive) -- has some housecleaning of her own to do. It\u2019s not just the technical teams that have a problem, but the HR team members under Atwood who heard and saw Fowler\u2019s evidence and felt compelled to dismiss her. It\u2019s almost as though they prioritized the good of the bottom line over the well-being of their employees. Where could they have gotten that idea?\nAs I read various reporting on the revelations, one particular headline from Ars Technica caught my eye: \u201cEx-Uber engineer alleges sexual harassment, CEO reacts by promising investigation.\u201d The key word in that headline is \u201creacts.\u2019\u201d As a CEO, you need to do more than \u201creact\u201d to these incidents. You need to be proactive in making sure this never happens in the first place, and certainly not repeatedly, as Fowler claims.\nFowler says other female colleagues reported similar complaints against the same manager, characterizes Uber as being \u201cin organizational chaos.\u201d She alleges that her performance score declined, and that she was eventually threatened with firing, for reporting her experiences to HR. When she joined the company in November 2015, she writes, \u201c\u2026 the organization I was part of was over 25 percent women. By the time I was trying to transfer to another eng organization, this number had dropped down to less than 6 percent.\u201d\nI can\u2019t imagine why.
