The question is right in the title. I've tried more Buddhist mindfulness techniques but the angry keeps returning.

So I'm curious how Taoism handles this most tricky/powerful of emotions? With the world drunk on anger, how do we deal with it?

In my case I'm having issues getting over some things that have happened to me that I feel are unfair, particularly something at work. I'm reminded of the incident daily in the course of my work (it was an error I feel was handled in an overly heavy handed way) and I am concerned said incident might be repeating soon (an error occurred that's somewhat similar and although I followed procedure I'm concerned I'll be thrown under the bus again.)

I'm keeping it vague on purpose. I don't think the exact circumstances matter so much as the general sense that a thing happened and I'm still angry over it and can't seem to get past it.
