I have been in toxic places like this but I also wonder if being sucked into a dynamic so deeply that one would go out to ostracise another person on a several month long campaign is well spent energy and healthy for the person doing it. Maybe that person really was so horrid that they deserve it idk but it says as much about the accuser as it does about the alleged culprit. Most work place dynamic I have seen there was always one person that stuck out in a negative way, and the places where this wasn't as much an issue was when all the others (who were normal) were able to see the BS and not give that person a platform to begin with. Maybe this should have been spotted earlier and management should have responded quicker rather than letting things become this toxic, but since the author seemed part of the management the whole thing just seems off. Hard to say as an outsider what the situation there was other than something doesn't gel.
