I don't think all companies are in the same position as Disney though. Every situation is different as well, so standardizing things is not that simple. Disney got a lot of praise, and some criticism, for the quick hook on Roseanne. Now that had immediacy, an unhappy set of coworkers, a history of her running her mouth, so that is one situation. Then almost immediately, here is Gunn. They did the same thing, but the situation ends up being different. Now they get a lot of criticism, and probably still more praise, for the quick hook, but the follow on because it wasn't immediate, the coworkers liked the guy, and his path had changed and been documented that it had changed, so the story just won't die. And the issue with the actors is a problem. Because Disney needs talent. They can't alienate it but nor can they alienate the fan base.
Now look at Lasseter. Here they didn't give the quick hook. They gave him time, they did an investigation, they eased him out. The situation probably had immediacy, the coworkers seemed split, but not much history nor much proof other than a few things in the press. It dragged on and on and what did we do? We hammered Disney on it. Over and over. How long it was taking, how ridiculous it was. There's a whole thread on it.
So twice they did a quick hook, once they did a slow ease out, and EVERY TIME a significant number of people hammered them for it. One size does not fit all. Companies are kind of adrift. And it is worse because Disney is Disney. Someone brought up Comedy Central and how much better they handled a similar situation to Gunn, but Comedy Central isn't Disney. They don't cater to kids, they don't run beloved theme parks, they don't have one of the most well-known corporate characters on the entire planet. So Comedy Central has a lot more flexibility in what they can do.
There just isn't going to be an agreement or standardization on this. And these situations are how executives justify their outrageous salaries. Eisner is paid an insane amount of money, but he has to deal with Lasseter and Roseanne and Gunn. Part of sitting in that seat, and getting that ridiculous check, is dealing with these absurd no-win situations. I still think he's stupidly overpaid, but he's also going to be vilified by a significant portion of the population every time this kind of thing comes up, because there is no way to win.
