If you think your job is hopelessly difficult, you may be right. Particularly if your job is public administration. Those who study or practice public management know full well the difficulties faced by administrators of complex bureaucratic systems. What they don't know is why some jobs in the public sector are harder than others and how good managers cope with those jobs. Drawing on leadership theory and social psychology, Erwin Hargrove and John Glidewell provide the first systematic analysis of the factors that determine the inherent difficulty of public management jobs and of the coping strategies employed by successful managers. To test their argument, Hargrove and Glidewell focus on those jobs fraught with extreme difficulties--"impossible" jobs. What differentiates impossible from possible jobs are (1) the publicly perceived legitimacy of the commissioner's clientele; (2) the intensity of the conflict among the agency's constituencies; (3) the public's confidence in the authority of the commissioner's profession; and (4) the strength of the agency's "myth," or long-term, idealistic goal. Hargrove and Glidewell flesh out their analysis with six case studies that focus on the roles played by leaders of specific agencies. Each essay summarizes the institutional strengths and weaknesses, specifies what makes the job impossible, and then compares the skills and strategies that incumbents have employed in coping with such jobs. Readers will come away with a thorough understanding of the conflicting social, psychological, and political forces that act on commissioners in impossible jobs.
