You think that’s bad? Eventually, they’re going to ask you to memorize ALL of the zip codes your center handles locally, and some that are even out of state (the outbounds), no matter what you’re doing (load/unload) but especially if you are put on sorting detail. And, they’ll only be raising you $1.00 for those 40 – 60+ zips and the brain cells “wasted” on storing them long-term, and on YOUR OWN time.
Those couple little memorizations of the key safety habits and procedures are going to seem like a cakewalk at that point. And if you ever manage to make it to Driver, well guess what? There’s hundreds more things you’ll be expected to learn and know within a split second, and the OJS will be asking you every single one of them during your training and while you’re trying to focus on the road and your next few stops, so you’d better get the basics down quick.
For the immediate term, I’d suggest you get an area map from one of your management or sups which specifies the entire center’s radius complete with all zip codes and start cracking at them now, in addition to all of their "safety drivel" (which is really in your best interest to know, because it won't be their ass getting busted up for not knowing and following them, but yours). Oh – and by the way, they’ll also be asking you to memorize streets in addition to the zips, or at least this is what I was told would be required at my center.
Good luck!
