It was my third day on the job today and the second day in a row that I've made the drivers off by my crappy loading skills(I know people say drivers are pissy regardless, but it was plain as day compared to the other handlers). I don't understand how I can load the boxes in order tightly when I get them at random. If I get a package that would fit better in another package's spot then I may have to move five of them to get just that one in the proper area, which wastes a lot of time. Can any handlers give me their strategy for creating a good foundation of packages so I don't waste massive amounts of truck space? Or is it really just your best judgement? Thank you.
