Human resource management, or HR, is the process of working with people so that they and their organization can reach their full potential. In fact, human resource management is the use of human resources for the goals of the organization and includes activities such as recruitment, training, payroll and organizational relationships. In other words, human resource management is a function in the organization that maximizes the performance of employees in serving the strategic goals of the employer. Human resource management seeks to find out how people are managed in organizations, focusing on policies and systems. Human resource management units and departments are particularly responsible for a number of activities, including recruitment, training and development, performance appraisal and rewards (for example, payroll and benefits system management).
