They also said those were their goals. They didn't mention their actual turnover. So while Zappos may have lower turnover than Facebook, it's because they're optimizing for that condition. Zappos is explicitly creating a culture of longevity.
I agree that Zappos is optimizing for low turnover. I cannot comment on Zappos specifically because I don't know them, I'm just pointing out that some companies optimize for low turnover in a very poor way, so I suggested that how a company achieves its turnover is more important than the turnover itself.
I suspect we are in violent agreement on this, just saying it in different ways.
