The strategic and cohesive approach to managing people effectively and efficiently inside a company or organisation so that they contribute to the company' competitive advantage is known as human resource management, or HRM for short. Its goal is to optimise worker output to support an organization's strategic goals. The main focus of human resource management is on systems and policies that are related to managing people inside organisations. HR departments are in charge of recruiting, training, development, performance reviews, employee benefits design, and reward management, which includes pay and benefit administration. In addition, HR deals with industrial relations and organisational transformation, or how to balance corporate procedures with legal requirements and collective bargaining agreements.
