While the operation and structure of the public workforce is not a matter that is on the minds of most, the consequences for the nature and effectiveness of government are substantial. The Fragility of Merit provides a detailed examination of the importance of a professionally competent and politically neutral public service.Illustrating the fundamental fragility of the federal civil service in the United States and the underlying concept of merit in public employment, J. Edward Kellough demonstrates how a particular view of presidential power grounded in unitary executive theory was used during Donald J. Trump’s term in office. Specifically, he reviews various efforts to subordinate the public workforce to presidential authority and explains how those actions threatened to undermine bureaucratic expertise that is desperately needed in government.The Fragility of Merit makes a persuasive case for protecting the civil service and for rebuilding a national consensus in favor of merit in public employment. It will benefit researchers, academics, students, and others with an interest in public administration, public personnel management, government, and bureaucracy.
