Ever see that show, How its Made? I could not work in some of those places that they show. Standing in front of some machine all day feeding metal into it or something. Or in some food places that process stuff. I think i would go crazy doing the same boring job over and over, every day, all day, 52 weeks a year. Some stuff may be cool, like "I work at the car factory" but riveting things as they move by on a convayer has to be the pits. even if the money is good, I could just not do it.
When I was younger, I worked in a box factory, alls we did every day, all day was build the same type of pallet. boring as hell. I lasted about 3 months before I couldnt take it. It paid well and was union. A lot of the guys were there 20 plus years. But it was just not my idea of making a living.
Cliff note: Boring repetitive jobs ****.
