Dr. Thomas Gordon, author of the phenomenal bestseller "P.E.T. ," expands the system he developed to help parents to encompass teachers and childcare workers. In "Discipline That Works," Gordon provides convincing evidence that punitive discipline is harmful to children and promotes self-destructive behavior and anti-social, aggressive acts. Instead, he offers an important new strategy to help children become more self-reliant, make positive decisions, and control their own behavior.
