This book is about the impact of psychological violence on the socio-economic development of a country. It is a practical experience allowing to confirm the existence and the significance of such an Impact. The public agents, producers of the public service, are a resigned victim of a certain psychological violence exercised by the administrative hierarchy. This results in a demotivation of the human resources of the public sector which itself generates a crisis of sustainable development, thus exposing the deficiencies of a public service in decay. It is therefore necessary and urgent to find solutions to this problem, in particular through the implementation of a real public management governance with the elaboration of a national strategy of human resources supported by ministerial organization charts inspired by the new public management and based on the effective practice of internal audit and control.
