Yes, I am talking about unloading at a store level.. I was the main unloader for a couple years before fixing/running my own teams at multiple stores, at different times of course. Just like 60SecondsRemaining said, the unload isn't complicated. When you're team actually works together they should have the line constantly cleared especially with one unloader.
How long have you been with spot? I haven't worked at a super Target or anything but 14 trucks a week doesn't seem out of the question, especially during 4th quarter.
And no, I'm not lying, no sense in that. You can go read many threads here and even some guides that will enlighten you on how the process used to be. What I'm talking about was not uncommon, at a store with a good process, great teams, and great leadership.
