From a Redditor:
I used to work at a weld shop that made a lot of stuff for military contracts. Shortcuts were taken at every opportunity, which compromised the product. Welds that were supposed to be checked by a certified weld inspector (CWI) were not. Documents were faked. Lots of things went out that door to our military and other government organizations that should not have. On top of all that, there were little to no safety precautions taken there.
The owner himself tried to come out into the shop and tell me to weld on a 16-ton frame while it was suspended in the air by a crane with a 10-ton capacity. He wanted me to stand under it and make the welds on the bottom of it. That's just one of many, many dangerous situations he tried to put me in.
One day, he told me to do something, and I didn't know any better. Then, an older welder came by and told me to stop because it could kill me. A few seconds after I walked away, a piece of hydraulic equipment I was working with failed and went flying right past where I was previously sitting. I would have died if that old timer hadn't told me to stop.
