Ive unloaded trailers for a year now. Preload sup never has me SPA, load trucks, work small-sort/pick-off/split its always either unload or sort. On the sort end, one of the belts is about 6" above my shoulders and I'm 6'0". And of course every trampoline, generator, mattress, tire, bag of dog food goes to that belt, because of course it does...
I started driving last peak season and the dude loading my truck had misloads everyday. And they werent just around the corner, they were like 45 minutes away because for some reason, the dispatcher doesnt put routes in order next to each other so if there was a misload it wouldnt be a SUPER big deal, just run it and be done. Still dont understand that but anyways. There was one day where he misloaded 15 stops which accounted for 22 missing packages lol. But the truth is, Im not sure I would have done a better job really. The loaders are stretched thin and almost always load multiple trucks, and with 5 unload teams rolling full blast during peak, the amount of volume coming down the belt at once is insane. So I brought him a coffee everyday regardless and gave him a $100 giftcard at Christmas because I know its not easy
