Hello! Let me tell something as well. I'm a small lady, I mean short and not big whatsoever; I've been working as a preloader for more than three years, and I definitely have something to say. Every shift I've got four trucks to load , 1200 pieces or so all together. My drivers respect me , and first of all, ASK yours what they prefer to have on their trucks, each of them. Listen to them carefully, try to do your best. Second, pay a lot of attention to the order of next day air stuff; they don't have too much time to redo your job when they deliver it.
Third, as a rule, shelves up to 5k are occupied with business delivery: bulk stops put on the floor, all packages belonging to the same address together! Light packages and envelops stuck between two boxes belonging the SAME hin number, or in a strict order. RDLs and RDRs can be loaded at the end of the shift.
If you have any questions, please, feel free to ask me
