Did they bother talking to any Netflix Shipping Center pickers? I'd imagine that's a significant chunk of employees/temps that they employ.

"After working at Netflix for a while, it starts to get boring and it really brings your emotion down since there's not many interactions with your fellow coworkers, like for me, sometimes I feel really shitty after shipping for about three and a half hours and that's why I try to do many talking, walking during our breaks."

Just a small sample size, but I could imagine that job sucks a pretty big one, especially if your manager/quota-bot is on your ass 24/7.
