I did a similar job for UPS, but at an airport before school in the mornings (~2am-6am). Unloading the containers from the big plane, then sorting all those boxes, and finally loading the smaller planes or trucks. Everything was timed, and it was tough cold work (middle of winter, in a cold part of the US, at an airport where there is nothing to stop the wind), but its totally possible. Comically enough, the part that stuck with me the most was how bad I was at memorizing the codes for the various trucks/locations as well.
