In today’s highly competitive environment, companies’ traditional sources of competitive advantage, such as technology, patents and economies of scale, have been weakened by globalization and other environmental changes (Ulrich and Lake, 1990). As an alternative, a skilled, motivated, and flexible workforce can help develop a company’s sustainable core competencies (Levine, 1995). Therefore, HPWS tries to provide an edge to the employees by providing them a competitive advantage over others as it is traditional HR practices are not sufficient in today’s scenario.
