We had something kinda similar at my last workplace.
A guy, “Bob”, with the worst attitude you’ll ever come across. Total nightmare. Multiple times on any given day, he’d put down and even threaten people or rat them out to their bosses if some tiny little detail didn’t go the way he liked it. When said bosses reacted indifferently, he’d full on stalk people before and after work to have a go at them. For this and only this purpose, he even drove to a guy’s house several towns over.
At last, he got reprimanded (kinda rare in Europe) and was fired (even more rare) within a few months. And only because that specific company was generally very intolerant of this sort of behavior.
For a long time after this whole ordeal, if somebody displayed a bad attitude at work, we’d say: “Hey, look, he’s pulling a Bob.”
