Introduction
Human Resource Management (HRM) is a way of management that links people-related activities to the strategy of a business or an organization. Armstrong (2000, 2009) defines Human Resource Management (HRM) as a strategic and coherent approach to the management of an organization‟s most valued assets; that is, the people working there, who individually and collectively contribute to the achievement of its objectives. Smilansky (1997) considers the overall purpose of the HR Function is to enable management to enhance the individual and collective contribution of people to the short and long term success of the enterprise. Schneider (1994) defines HRM as the policies, practices and procedures organizations use for the attraction, selection and management of employees. Over the years, the role of HR managers has changed in response to changing social, economic and political conditions and to the advances in technology. This role is still evolving dynamically
