IMO, it is a very suspicious sub. It is the only left-wing themed sub that is allowed to reach the front page. After a long time in which no left-wing themed content ever reached the front page, suddenly numerous threads from "antiwork" appear every day.
It is filled with spam about very rude and incompetent managers and the most common way disputes are resolved is by moving to a new job where the manager is less rude and incompetent.
Anti-work is inherently reactionary. It tries to shift the blame away from capitalism and onto labor itself, that we shouldn't oppose bourgeois labor relations but should oppose work as a whole. It also gives right-wingers an easy win since it makes "the left" look like buffoons who think you can abolish work, and fits into their stereotype of a lazy hippy leftist who refuses to get a job. You can't reform a sub that is based on a reactionary premise from the get-go.
