Today’s HRM, its position and roles (strategic partner, administrative expert, change agent, employee champion) has undergone five key stages of evolution, changes in organizational structures. At the early stages, HRM was positioned within different departments, as Labor/administrative manager and Welfare officer with roles: administrative expert and change agent. From later to modern stages (Personnel management, HRM and Modern HRM), HRM, by obtaining new roles (change agent and strategic partner), become mostly complected, complicated and managed to operate as separate department, on the same level of importance as financial, strategic, marketing and other departments within organizational structure.
