My assumption is that a repeated, long-term pattern of harassing behavior wouldn't be tolerated unless the guy really was the goose that laid the golden egg.
On the other hand, what kind of claim does she have, really? Monetary damages are probably limited to 2x her salary because of how short her tenure was. Let's say that's $300k and it costs Uber another $50k to hire and train her replacement.
I don't know what this guy's job is, but replacing *him* may be something that has a direct cost of $100k (recruiting, signing bonus, etc) and indirect costs due to workflow disruption while he's being replaced. It's not impossible those could add up to another $200k or more -- business disruption is expensive.
