If that is not an option, i just let out my anger, emotions are not made to be surpressed.
Shortly at my weekend job,I had a huuuge argument with my foreman at work. We shouted at each other so loud the whole friggin storehouse could listen. It ended up with him leaving the place early, so we had to do the rest of the work without him.
He and me are pretty similar in character as far as i can tell till now. Today we had to work together again and after we had let of the steam back then, there was no hard feelings from either side. We actually get along really great today.
One can say alot about myself, but not that i am dishonest (exceptions are: Customers,Pupils,some parts of family, short: people you have to deal with and lying to them shows much more advantage).
Let out your anger when it builds up, so the pressure cant harm yourself. After all you are the protagonist of this story of your live and protecting the sidecast isnt worth it.
