My worst job was a short stint at a plant, in Waco, taking summer classes at MCC. If you ever cut open a hollow door, the interior is braced by corrugated cardboard that is glued together to form a lattice work. The facility was a non-a/c, non-insulated metal building that averaged about 115 degrees. It had automated glue guns, and band saws. The glue guns ran a little "rich" and would spill glue on the floor where it would promptly stick to the bottom of your shoes. This would create a situation where it was unavoidable to step on random small sheets of cardboard, and cardboard dust from the bandsaws, so you were constantly having to clean your shoes.
There were many middle aged people stuck in this dead end hell hole.They were way too old to be doing this kind of manual labor. Being the youngest there, by about 15 years. I got the worst job, loading the lattice frames onto pallets at the end of the assembly line, we produced several thousand a day. They came off the conveyor in groups of five, and fast enough that you would have to rotate about three feet every 2-3 seconds, from a bent over position. I could do this for about 30 minutes straight before my back would give out. They had six other people that could make it about five minutes each. I would rotate to their positions for 30 minutes to give my back time to rest, then it was back to being crouched or bent over stacking again. I did this for about a week before I had enough and went to work at a full service gas station.
