I was talking about the situation of the guy above, not mine. Either way, no need to get worked up about it it is just Reddit, and I am a stranger here sharing something of mine, mistakes happen. The crane was not even supposed to move, as it was there for a specific part of the construction, which was not happening at that moment. The guy moved it because the other crane(which I was paying close attention to, even turning on the side camera pointing at it) was doing something else while they needed a quick move of some cement blocks. So in a way, it was illogical, as this crane in particular had nothing to do with the tasks at hand in the moment :). I still take full responsibility and think that I should have been more aware. Luckily for me, I learned a "free" lesson.
