Today was the end of my second week preloading trucks off the belt. Running out of room in trucks is becoming less of an issue and I'm getting slightly more efficient at finding the right shelf, no misloads etc. But loading 4 trucks at times becomes extremely stressful and overwhelming, I frequently find myself around half way through my 5 hour shift with massive stacks of boxes outside my designated trucks (~250 pcs/each). Is this a normal part of the learning curve or am I just inefficient? Every driver I've met has been incredibly nice and helpful. I seriously strive to become as efficient as possible, and seek any pieces of knowledge or advice any of you may have.
