This is true, but I should point out that an organization with foresight would not permit harassment of employees, because the long-term cost of the lawsuits and bad publicity will be bad for the organization.
But Uber's entire business plan is about flouting rules and sustainability so that they can become irreplaceable. The sad fact is that they're probably being entirely rational. What's right is often unprofitable, short-term and long-term. Unless they have a big exodus of talent or customers, even a report this embarrassing is unlikely to slow the juggernaut.
That's Uber's strategic focus publically, but HR is an internal department and could conceivably be different, just like how their Marketing team almost certainly doesn't flout (or at least emphasize) flouting of laws.
Working for the organization should also mean avoiding potential lawsuits
Also working for the organization doesn't mean working for that specific middle manager who keeps harassing co-workers.
Yep. No fan of Ellen Pao, but it seems obvious HR did her no favors over at Kleiner Perkins.
