Unload is cake, dont fear it take your time. Preloading package cars is the worst. Missloads, late air, miss load air, bad loads are only the few to start. Plus you will walk 5 miles a night. I've dont unload in the past, cake compared to preload. Most drivers never did either unload, preload, load and sort. Most did debag, small sort and audits.. otherwise easy jobs. UPS rewards those whom have it easy... Thus a lower stock price.
