This book explores contemporary and historical examples of bureaucratic discretion to describe a continuum of resistance to authoritative directives by hierarchical superiors. Resistance ranges from blind obedience or complete nonresistance to street-level opposition; in between these extremes, however, are minimal compliance and resistance sanctioned by immediate superiors. Although politicians may pass legislation, the subject of bureaucratic implementation or lack thereof remains an area of vital concern. Grounded in administrative theory (beginning with Woodrow Wilson’s seminal discussion of the virtue of adopting a businesslike approach to American governing) and emphasizing the power of street-level bureaucrats, the aim of this book is to expand awareness of the potentially dangerous power of insulated bureaucrats.
