Worked as a trainer to teach new employees how to load trucks in college at a large UPS distribution site. There is an ideal way to load trucks for safety and efficiency i.e. heavy items on the bottom, small light items on top, and hazmat on the bottom sides. This is easy to achieve when the package traffic is light and possible even during moderate package flow. You can think of this process as physical Tetris, which is a great workout. Unfortunately when the package load is very high, loaders just end up hapzardly loading trucks to keep the package flow going and to meet nightly deadlines of filling x number of trucks. This problem was compounded by a high turnover rate, which didn't exist before the addition of health insurance effectively cut hourly salary in half. This process may be more efficient today with better scanners, that hopefully no longer requires loaders to manually key in tracking ids.
