There’s always some jackass pulling this kind of thing. I’ve even heard of people cutting off locks for locking out things, including a shit like breaker boxes while a guy was working on wiring. Jackass coworker pulled that, blew the guy who locked it and tagged it right off of his ladder and into the hospital. The boss suggested to the idiot that cut it off that he could either resign immediately or wait until injured coworker came back from the hospital and rehabilitation and deal with him personally. Idiot stick quit.
