Because small and medium-sized enterprises generally lack a clearer development strategy, it is impossible to have a clear plan in terms of human resource management. They can only take one step and look at one step. Recruitment is only considered when there is a lack of qualified personnel, and training is only considered when the quality of personnel does not meet the needs of enterprise development. When the recruitment company is in short supply of talents, it will adjust the company's salary system arbitrarily, raise the salary level, and attract talents. When there are idle talents, they find excuses to lower their salaries arbitrarily and reduce business risks. Due to the lack of planning, there is greater arbitrariness in human resource management, which makes personnel mobility greater, and ultimately affects the normal production and operation of enterprises.
