I unloaded about 5,100 packages tonight! WOO! Only my lower back and bum knee hurt! Well, my finger joints are sore when I bend them...but there fine. I'm usually the ireg carrier now if there are more than 1 person in the trailer! That means I take iregs (non-package and/or any packages over 70 pounds) out of the trailer and to the ireg chute. I did my first 2 trailers solo....in the second one there were two 95 pounders, two 107 pounders, and a 81 pounder all the way in the back....iregs are supposed to be loaded in the first 50% of the trailer....so the loader that loaded was a prick and didn't do his job right! The guy who called me small fry apologized today and said I'm a damn good worker.....I accepted his apology of course!
