I'm a loader, pretty new and not good at building walls in clinch moments when the trailer's getting buried. Which is about 99% of the situations I'm in the past few days. The only technique I know of is to leave space between rows so you can throw the light stuff back; and heavy/ big on the bottom, light/ fragile on top. Today they took me over to unload the brown UPS delivery trucks, and the guy that I was working with was nice enough to give me a bunch of advice on how to maneuver the boxes. It was pretty much the only practical advice I've gotten so far and it's helped considerably. But maneuvering and wall-building are two different things, the latter I know little of. The past few days have been absolute hell, I get put in the worst loads by myself and get yelled at every 10 seconds even though I'm doing my best. Couple times I almost flipped on my supervisor, I have a bad temper that doesn't go well with this kind of job. So I decided I'm either gonna give up and quit or learn how to do it the right way. There probably wouldn't be a problem if there was some technique as to how to build them, can anyone give some advice?
