I started today on preload and got put loading 3 trucks. One was pretty easy, the next moderate amount of big heavy boxes but the 3rd was complete chaos. About 350 pcs on it with at least 1/3 being large very heavy pkgs in bulk RDL and RDR. I started stacking out beside the truck per advice of the Sup but it quickly got out of hand. After 3 hrs the guy across from me began shoving every pkg off the belt onto the floor. Any advice on how to avoid that mess? *looks for a serum to become the Hulk* Im a chick and not sure how to work around my lack of strength for repetitive large qty heavy boxes.
