Being the fall guy
Whether you are fired for being the fall guy, endure the incident with some dignity. Work on easing your instincts to blame and recriminate, to feel bitterness and resentment. Find peace in that you might have had opinions, and you expressed them, but that you did not have the authority to change the way things were being done. Take it as an opportunity of learning about yourself. Somebody had to be fired, that is the way it is in business. Next time it won't be you.
