@Gerard Pietrykiewicz an unfortunate reality is, depending on the situation, you may not have the luxury of time to cool off or remove yourself from the situation that is aggravating you. I found that recently when I had to fire somebody this week (who did have bad intentions), things were moving fast and I always needed to be prepared for the next problem, hour-by-hour. In the end, what got me through was the reflection on my tenure and contributions at work; and the self-reassurance that everything I have done up to that point has been for the good of the company in some way, shape, or form (even things that do not superficially appear to be the case, as you are aware). The saying "do not attribute to malevolence, what can easily be explained by ignorance" is a powerful thing I often repeat to myself. In the end, I encourage you to be steadfast in your principle, and not allow the ignorance of others to erode the thing that makes you invaluable in a work setting; to not dirty the sacred trade of management with impulsive emotions. I suppose you can call it the 'stiff upper lip' approach. To leave you with another quote I like, often mistakenly attributed to Confucius: "It is only when mosquito lands on your [privates] that you realize there is a way to solve problems without using violence"
