Human resource management is an important field that directly impacts the development of enterprises and the quality of employees’ work. With the rapid growth of society and the intensification of competition, enterprises are facing more and more pressure, and employees are also under more work pressure. Therefore, optimizing the enterprise’s human resource management system to relieve the psychological pressure of new and old employees has become an urgent research topic.

Based on the analysis and dismantling of the existing human resource management model, this study improves the structural modules that can be optimized, such as the suitable working environment and resource support provided by the company, the promotion system obtained by employees, and reasonable welfare benefits. The improved and optimized human resource management mode was compared with the traditional one under the same conditions, and SPSS23.0 software was used for correlation detection. This paper explores the relieving effect of the optimal management mode on the psychological stress of employees.

The employees who accepted the optimal management mode were more satisfied, the number of employees with psychological stress decreased significantly, and the self-evaluation score was higher. The difference was significant (P<0.05). Employees who accept the traditional management mode have no noticeable effect on relieving psychological pressure and low overall satisfaction.

The optimal human resource management model proposed in this study explicitly affects the psychological pressure of new and old employees and improves job satisfaction and performance.
