I mean, Amazon has traditionally been a pretty great place to work, even in fulfillment centers the pay is above industry averages and FT employees have perks they wouldn't get anywhere else.

They're having some issues scaling that while maintaining good conditions (esp. when contractors are involved), but we're talking about a company that has nearly doubled its workforce in the last two years. I doubt very much that any company in that size range could do the same without big problems; clients I've worked with and talked to see similar problems scaling from 50 to 100 employees, but no one cares because the company isn't a household name.
