Although all types of resources are essential for organizational success, the literature seems to accept that human resources and their management have a significant impact on organizational performance. Assuming human resource management (HRM) does influence performance there appears to be no consensus on the nature of human resource management (HRM) practices and categorization of performance outcomes, also little attention is paid to exploring the processes through which the impact takes place. The paper reveals the nature of human resource management (HRM) practices and the content of organizational commitment and job satisfaction. The paper proposes an answer to the question - how human resource management (HRM) practices can influence organizational performance. The approach of impact is based on AMO framework, which discloses the importance of employees abilities, motivation and opportunity to participate. Besides, the paper presents empirical research showing that skill-enhancing, motivation-enhancing and engagement-enhancing human resource management (HRM) practices have a positive relations with affective human resource reactions: organizational commitment and job satisfaction.
