>>3 I kind of disagree on many points in there, but here's what I think:
If you want to reduce the heat in a stressy situation, you can concentrate on 2 things:
#1 accept the situation you're in. It's simple. You're in the middle of a shitstorm. And it's about to go down, whatever you do. There is nothing you can do about that, even if you're not to blame. Even if you could have prevented it, that time is gone, accept it, and think "Well, it can't be helped".
#2 After accepting the situation, and also the reason for accepting the situation is for the following purpose: Concentrate on one thing and one thing only. Not who to blame, or who is at fault, or how fair the situation is, because most of these can't be helped when you're already there. But
instead concentrate on how to solve the
problem itself. The sooner you solve the problem, the better for you, and everyone can go on with their miserable little lives around you. Additionally, being a problem solver puts you in a position where you cooperate a lot with people who have the same interests. That means you produce value to those people.
Even if your janitor coworker is a dick, if you just clean up with a smile and after that just keep out of the part where they try to give someone the blame stating "This is a problem we've already solved, let's move on to everything else that needs solving *smile*", you'll even gain a lot of recognition.
Just an advice tho, what I wrote above doesn't mean you should spoil your coworkers or do their jobs instead of them. Don't let yourself be used. It's more like approaching the same situation a different way.
Also a small bonus trick: If your coworkers can't distinguish milk chocolate from dark, treat them like they're idiots. Treat them like a 5 year old, who really doesn't know the difference, and try to tell them nonetheless why and what the difference is instead of telling them "No! You shouldn't put that there". It has a different effect on people. When someone treats you like an idiot, you want to prove to them that you aren't one. If you don't allow someone something, they will sure as hell do it, just to spite the rule.
