I read an article last summer about working at those large distribution centers. I don't remember if Amazon was explicitly named, but that is who I pictured while reading it.
The author of the article went to work at one of these places to get an inside perspective. The employees were all through temp agencies, low pay, no benefits, very rigid about sick days, lunch and bathroom breaks, etc. And according to the author, you could work like a dog and hardly ever meet the quota for items picked per shift.
Anybody ever work at an Amazon distribution center, or know somebody who did? We don't have any around here.
