I definitely learned about each of those rules the hard way. I have 'don't ever date a coworker' on my list, too. I'm going to cut and paste what you wrote to remind myself how to act in group situations-- it helps to have reminders.

Chaotic workplaces where management refuses to plan and only reacts to crises are unbearable. My new rule about those places, also learned the hard way, is that if they are unwilling to change, I am unwilling to stay. I also decided to leave my field (systems administration) and go for something that didn't involve being on call 24/7 (software development).

Is getting out of that workplace an option? Or imposing some kind of order?
