Take it easy, bro... nobody said you were wrong, just that it isn't a certainty that the person was in the wrong based on your very limited initial description.

Take it easy, bro... nobody said you were wrong, just that it isn't a certainty that the person was in the wrong based on your very limited initial description. This was your friend's story, right? Are you sure you know ALL the details and not just the company's side? Were there extenuating circumstances -- any liquids nearby, were all workers provided proper footwear? You didn't say he was running (however, why was he running? did a manager tell him he needed to hurry, did he not have enough time for a bathroom break? etc) and stairs come in all shapes, sizes, steepness, lengths, materials, and hardness of the floors under them. Nothing can 100% prevent injuries, but you can try to avoid the worst scenario. It's a factory, I get it, maybe it's not possible, but I would want to know if there had been any prior similar incidents. In any case, no matters whose fault, it still doesn't seem necessary to tell the guy to "fuck off." We're not looking to try the case, just pointing out that it's pretty ridiculous to immediately claim a workplace incident is entirely the worker's fault.
