Basically you got DQ'd because your SPHOR basically never increased.
Not having loaded a car doesn't mean anything UPS hires driver off the street that somehow seem to be able to figure out how to find packages that are loaded in the package car. Saying the HIN # system was new to you is BS you deliver Sat Air you at least have some knowledge about them and you have been working at UPS for over 7 years. Also packages these days are rarely put on the shelves in exact number order. There isn't enough room in each section with the number of package that have to be stuff there. It also doesn't take a rocket scientist to sort out the packages for the next 10 to 20 stop and move on.
Did it occur to you that if the package where all over the floor something might be wrong with the way your driving the vehicle.
As far as area knowledge if that was a problem why didn't you use a weekend day or two and a map and go drive around the area you where delivering in and get familiar with it. I understand you where giving some new areas each day but the majority of your route was the same each day your number should have gotten better.
There is an Pt Local Sort / Sat Air driver in the building I started in that gets DQ'd ever time he tries to qualify to drive he has one speed and it's called slow motion.
first off on Saturday's we don't use HIN#'s, i have an average of 15 stops, so no need for them. and yes with what i do in the building i never used those numbers before, nor heard of them. and i don't expect them to be in exact order but i will sometimes find a 3000 all the way in the back etc.
when i say packages all over the floor i'm talking about before i leave the building, because there's so many packages there's no room for them so they have to stuff them on the floor up to the roof. on average i wouldn't even be able to walk to the back of the truck, unless i had 120 stops or less.
i did drive around the area i was delivering a few times a week. area knowledge would take weeks or months to learn it, not 3 days like my sup expected of me. and i was just getting to know most of it too.
i had another driver ride with me a few times and he said my driving was excellent, i had the diad down and a fast pace, the only thing i needed to work on was organizing the back of the truck.
