Human resources are the greatest assets of an organization. HRM involves acquiring, training, appraising, and compensating employees so that organizational and individual goals are achieved. The key functions of HRM are acquisition, development, motivation, and maintenance of human resources. HRM helps organizations attract and retain talent, while also providing employees opportunities for personal and professional growth. While HRM supports the organization, its functions like training are sometimes seen only as costs. HRM also faces challenges like adapting to trends in globalization, technology, demographics, and changing work styles.
