Not exactly sending them to coworkers, but I did kind of refer a coworker to one once.
I work in 911 dispatch, it’s kind of hard not to end up a little desensitized to some crazy shit. We once had a call about some kind of industrial accident, someone’s arm caught in a machine or something along those lines. Obviously not going to share too many specific details about the incident, but we did have a teams on location ready to do a field amputation if needed, but luckily they were able to get the person out without any major injuries.
So our conversations tended to be about a lot of the crazy gory fucked up things we’d taken calls about or otherwise seen or heard about, and I mentioned the Russian lathe accident video to one of my coworkers (don’t look that up if you’re not the kind of fucked up who can deal with that sort of thing, it’s a guy getting caught in a heavy duty lathe and spun around and mashed against the machine until someone comes and hits the emergency stop, at which point there’s nothing much left of him)
That piqued her interest, and she went and watched it on her phone at her next break.
I wouldn’t send the video to anyone, especially not out of the blue, and when it comes up I warn people not to look it up if they’re the type of person who would be significantly disturbed by it. In general I won’t even mention it to people who don’t work either in some sort of emergency services or medical sort of field where we have to occasionally deal with that kind of thing, or in a machine shop where they’re working around those kinds of machines, and even then it’s something that only gets brought up to certain people in certain contexts.
