dropping off parcels after hours than the people at UPS.
UPS relies on a lot of part timers in the warehouses. They have to earn their keep as a part timer for a few to several years before they are offered full-time employment.
At least is the way UPS operates around here.
So I am suggesting you are seeing the difference between part time and full time employement at the tow different places.
