The best thing to do to survive is to first realize that your work friends are not your friends. They are colleagues.
You will compete for meager raises, and you will play musical chairs when the layoffs come. Not friends but competitors! Make sure you always get a chair!
Whenever possible remind your boss about mistakes colleagues made. Undermine their good work and focus on the bad they did. When they make a mistake make sure it becomes as public as possible. If they do a great thing play it down and focus on the great things you did.
If you catch a coworker making a mistake allow it to continue on. Do not warn them. Let it move down the value chain until it becomes very expensive to fix. Never help them, let them flounder and fail quietly until it becomes a big problem. Then you can point fingers at your coworker and get the boss focused on how much that mistake cost all of us.
This is how you survive at Raytheon.
