I don't think the business, at least at that level, is that way as much. When HBK and Hart had their "Sunny nights" dustup backstage, HBK walked and filed an unsafe work environment complaint.

Sometimes it happens tho. When Regal exposed Bill Goldberg on Nitro. I always heard Larry Hennig and the Crusher (I think) stopped "cooperating" with the Road Warrior and messed them up nicely. Inoki pretty much shot on Ali in their wrestler/ boxer thing. Fucked up Ali's legs really badly.
