I know you did mean firing, but even that wasn't necessary. In germany we actually force companies to at least try and work things out. In order to fire someone you need 3 documented instances of misbehavior followed up improvement attampts, or an actual breach of law.
This gives everyone time to sit down, gain distance, sleep over it and calm down and try again.
Plus, if the feeling of not getting along remains after that, after some calming down it's often easier to work out a mutually acceptable separation. In a similar situation over here, Rick would've gotten a fairer treatment even on separation, other than "fuck you, bye".
