The idea of writing this book was conceived by the author while working in various organisations in the area of human resources for more than five decades in the country. Human Resources is the most valuable asset in any organization and management of its discipline is the most important activity on the priority list of management. It is an established fact that discipline is considered to be a fundamental tool in realizing the full potential of "Human Resource, hence its importance as a key subject in management, be it in our home, office or industry". A disciplined workforce in an industry is necessary for its working that in turn, is most important for well-being of the society and also for the prosperity of the entire country. Emphasis is on: What defines discipline? How did discipline originate? Why is discipline a significant study area? Who are the stakeholders for discipline? And finally, what are the basic concepts of discipline and its practical aspects? The book conceptually explains the nature, need and importance of discipline in the workforce. It contains the two most important topics, namely discipline and disciplinary procedure. I am confident that students and HR professionals will find the book quite helpful.
