At my site, my site supervisor is fantastic. Most of the employees are willing to trade shifts if needed. The pay isn't that good, but it is very easy. 12 hour night shifts are almost a killer because it is so slow. Anyone can do it, the hard part is never knowing what schedule you will end up with because of the turn over in personel, but the supervisor tries to work with everyone. No advancement posibilities. If you don't need stimulating work, it's perfect.
Supervisor and other employees willing to trade for days off.
Low pay, mundane work, 12 hour shifts sitting in a car.
