I'll probably be working at Pepsi in the warehouse loading trucks. I used to work nights at Wal-Mart stocking shelves, unloading freight onto the floor, and moving freight from the warehouse to the floor. I really enjoyed the work even though it was a little hard. Now I have an opportunity coming up to work at Pepsi loading trucks. How hard is the work? I have back problems and I can't lift massive amounts of weight, but I can still lift a pretty good amount of weight. What will I be using to load the trucks? Machines, Dollies? I just want a rough idea of what I will be doing. Wal-Mart was pretty hard work, will this be about the same?
