I bought Dealing with people You Can't Stand to pass some time while waiting...the perils of not bringing a book...
To my surprise, this turned out to be a little goldmine of good ideas, presented in a way that a lot of people can carry away the messages. If someone at work is chapping your hide, I strongly recommend that you buy this book, read it, and map out some strategies for change.
This isn't a "how to hurt the bad guy till he stops"--this is developing your own capacity to manage your emotions and think on your feet.
You can also study this book for Continuing Education credits for therapists and counselors. You could do worse.
