What's the worst job you ever had?

[Fish]

Worked shift work at a fiberglass insulation plant in McPherson during the summers when I was in college. Outstanding pay, but it was pretty tough. Worked 6am-6pm for a few days straight, then a few days off, then a few more days working 6pm-6am. The ovens that melt the glass were always running at around 3000°, so it was very very hot in the plant. And the fiberglass insulation would get in your pores because you were sweating so much, the itch would be unbearable for the first few weeks. And every once in a while, we would have to do an oven cleanout. Which required us to bundle up head to toe and crawl inside the ovens and scrape off the baked crap on the oven walls with a hand jackhammer. It was like being inside a ventilation shaft that was about 140°. Hot, dark, and claustrophobic. Awful awful work. But it was incredible motivation to finish college.
