There was an abusive manager (cursing, shouting, making subordinates cry) at a 200+k employee client I worked at. Subordinates told HR. I assumed they would fire him but they transferred him. I asked my manager because that seemed bonkers to me. He explained that that group had jobs to do that were low priority, had their own building, could only be transferred to. You couldn't leave except by quitting/retiring.
Some beancounter had figured out that the price of letting these horrible people wear each other out and quit was lower than firing for cause and facing lawsuits.
Sometimes at other clients I've wondered if the department I'm working with is their "roach motel" department.
I had heard of the Japanese just putting you in a room with nothing to do instead of firing you, but this sounds next level. They basically created a corporate version of hell, where people don't truly die but have to endure others sinners for eternity.
