Abstract
This examination of policies relating to the internal cultivation of human resources and high-performance work systems among a sample of Singapore-based organizations shows that the HRM practices under consideration reflect three distinct dimensions: internal staffing, employee development, and employment stability. Of the three dimensions, only employee development was significantly and positively related to high-performance work systems. Contrary to the arguments in the literature relating to internal labour markets, mutual commitment HRM, and high-performance work systems, policies involving internal staffing and employment stability were not found to be necessary components of the internally oriented HRM package.
