I've been going to training for 3 days at FedEx express and found out I'm loading air containers. I was hoping the luck of the draw would have me unloading. However both have plus and minus. He said about load 3-5 cans a shift. More thinking and moving around. Have to weigh and inspect the can before hand and fill the paper work to clear it for air travel. Unloading is nonstop and seems a bit more physical and fast paced but its mindless. The people that have done it, if you had to pick one what would it be? And if I wanted to unload instead. I still have to put in my 6 months loading? Thanks for any input.
