Constructive Criticism: A Handbook Speaking & Listening More Effectively in Personal Relations, Groups, & Political Activities By Vicki Legion (Gracie Lyons), 1976
Constructive Criticism is a wonderful example of the blending of valuable and powerful socialist theory with a practical, down-to-earth pragmatism. The result is an extremely useful manual for people who work together for positive social change. Putting Gracie Lyon's suggestions into practice will increase the power of people's work as well as their personal sense of well being and satisfaction.

NVC is a great recommendation. I need to get back in the practice. I haven’t read Legion, so I’m going to check that out.
