HR stands for Human Resources. It is also short for HRM, Human Resources Management. The HRM department is often also mentioned ‘HR’. Some people prefer people management. We quote from Wikipedia:
Human resource management (HRM or simply HR) is the management of human resources. It is a function in organizations designed to maximize employee performance in service of an employer’s strategic objectives. HR is primarily concerned with the management of people within organizations, focusing on policies and on systems. HR departments and units in organizations typically undertake a number of activities, including employee benefits design, employee recruitment, “training and development”, performance appraisal, and rewarding (e.g., managing pay and benefit systems). HR also concerns itself with organizational change and industrial relations, that is, the balancing of organizational practices with requirements arising from collective bargaining and from governmental laws.
