HRM is a set of distinctive activities, functions and processes that are aimed attracting, directing and maintaining an organization’s human resources (Lado and Wilson 1994). The HR function has grown substantially over the past few decades and now covers the whole gamut of people management processes. There are different views about the nature of HRM and there exists an enormous variety of HR practices adopted by various organizations (Boselie, Dietz and Boon 2005). Nevertheless, it is widely recognized that the key practices of HRM include recruitment and selection, training and development, performance management and pay (Shen and Edwards 2006).
