I'll list mine but it doesn't reach the same level as many of these stories. I got hired at a factory making engines. Everything was okay until I was given a switch to 3rd shift or get laid off ultimatum. The 3rd shift people had a game that involved throwing thin metal discs with sharp edges at each other across the entire production line. I got hit and cut more than once with these discs. When I complained to the foreman, he told me to deal with it and that they just do it to have fun. I assumed that would be his reaction since the workers weren't trying to hide what they were doing. I told HR about it, switched to being laid off and found a new job. The plant closed a few years later.
