My question is how is pay calculated. It is a little different each week. When my son first started driving while still preloading they paid him straight time for the first 5 hours of preload, then the rest of preload it was time and a half. Then the first 3 hours of driving was regular pay with the remainder at overtime. Each week has been a little different. Today's check was 8 hours of regular pay for preload, then the rest of the day was overtime driving pay. The only day that was different was a day that he only preloaded. That was 5 hours of regular with 3.5 hours of overtime. Can anyone explain this?
