Not bad once you get used to it.
Pros: paid breaks, accommodating management
Cons: long hours, continental shifts, tiring work
Long, 12-hour, continental shifts do feel like they take up most of your life but it's not a hard job and there's usually enough to do to pass the time fairly quick. Management were always very understanding and kind but the managers for Kelly Services (the temp agency I went through) weren't always coordinated. Easy but repetitive job and not nearly as bad as it first seems.
