The common agreement in human resource management (HRM) literature suggests that organizations willing to attract and retain human resources for running business in the future must change the prevailing situation where human resources are rather consumed than developed. In doing this, sustainable HRM has been introduced recently as a response to changes on societal level, labor market, and employment relations. Sustainable HRM is seen as an extension of strategic HRM and presents a new approach to people management with the focus on long-term human resource development, regeneration, and renewal. However, the attributes of sustainable HRM, as compared to mainstream HRM, are not clear. The paper aims at closing this gap by proposing and revealing the characteristics of sustainable HRM, namely: Long-term orientation, care of employees, care of environment, profitability, employee participation and social dialogue, employee development, external partnership, flexibility, compliance beyond labour regulations, employee cooperation, fairness, and equality. This is a theoretical paper.
