I used to work at a company named Lear Corp. that made the panneling for the doors you see in your cars. Namely the GM brand, but nonetheless, we were the people that made the fiberglass/vinyl molding for your cars. The arm rests, the speakers, wiring..all that we put in at the factory. I ran all the jobs along the line before I left, but the worst two I have to say on the line, were the punch press, and the molder. Fiberglass sticks into your arms and is hard to get out without a few home remedies. Very itchy too..and hot. It was ok money, but you have to be fast and precise to earn it. My mother still works there, but she doesn't have to do those jobs, she's elsewhere in the factory.
