Attempts to develop an appreciation of the first-line supervisor's job and his responsibilities to management, to his worker-subordinates, to his peers, and to himself are presented. In particular this document studies the making of decisions, and discusses do's and dont's of face-to-face problem-solving with a subordinate. A movie film brings out typical decision-making defects of supervisors and shows how these defects can hinder their job performance and jeopardize chances for promotion. (Author/NF)
