Health and human services depend upon their working groups for their development and allocation of resources, their standards of quality, and the evaluation of their success or failure. Despite the amount of time spent in meetings, very little has been written about the skills necessary for effective participation and leadership within working groups. With that in mind, Ephross and Vassil combine innovative group theory and practice in this "how-to" guide for professionals who take a variety of roles within the group. They draw on examples from social agencies, a hospital, a low-income community, and the boardroom, providing practical principles for day-to-day group life based on a democratic model. This revised edition also explores the changes that have taken place in the structure and operation of working groups in recent years.
