Personnel management regards people as "costs", employees are passive management, and human resources manage people as resources. It emphasizes giving play to the initiative of employees' supervisors. The reasons why personnel management turns to human resources are as follows:
1. The increase of labor disputes urges enterprises to think about labor relations;
2. The transition from manual labor to mental labor means that the employment of employees is not only the time and hands of employees, but also the brain of employees. The brain needs subjective consciousness to play a role, so it is necessary to make employees happy to engage in their own work, and encourage enterprises to regard employees as resources rather than just costs;
3. With the improvement of living standards, employees' work is no longer just to survive, but to achieve their own high-level needs, such as being respected, reflecting value, etc. The concept of regarding manpower as cost meets these needs.
In terms of management concept, traditional management is often associated with "power" in terms of concept and consciousness because it is the work of supervisor, deployment and promotion, and the personnel department is often regarded as the "power center" of the enterprise
The transformation from cost center to profit center requires that the human resource management of enterprises must play a new role in the work.
