M,

I am going to recommend the two communication books that I've found extremely helpful to me.

Nonviolent Communication: A Language of Life by Marshall B. Rosenberg

The Lost Art of Listening: How Learning to Listen Can Improve Relationships by Michael P. Nichols

This can applied to the workplace, family, kids, and H. These books also uses concrete examples as the nuts and bolts that you can actually use in everyday life.
