The New Yorker has a nifty-yet-brief piece of observational research on part of the Netflix process; incoming envelopes unloaded and outgoing ones loaded.

forty employees (“associates,” in Netflix parlance) are ready for work. The majority are women who were born in Africa and in Asia. At 6:30 A.M., they sit down in ergonomic chairs and begin the process known as “rental return.” An associate tears open an envelope that contains a sleeve enclosing a disk, tosses the empty envelope into a recycling bin, removes the DVD from its sleeve, checks the title on the DVD (when “Black Dog” arrives in a sleeve for “The Triangle,” the mismatched sleeve is discarded and “Black Dog” is re-sleeved), checks the condition of the sleeve (those with coffee stains or other evidence of having been used as coasters will also be replaced), checks the condition of the DVD (for scratches and cracks), and extracts customer notes (“THROW THIS DAMN DISK AWAY. IT DOES NOT WORK AFTER EPISODE 2, CHAPTER 4!”). Fingers flying and heads swivelling, the women each open between four hundred and fifty and eleven hundred and fifty returned rentals an hour.
