Is it necessary for Jiangnan University to recruit teachers?

Jiangnan University should be the first school in Jiangsu Province to promote or leave. Every year, teachers are eliminated, and new teachers must rank ahead of Jiangnan University in their subjects.

The system of "staying without promotion" is a kind of employment system widely used in enterprises, military, universities, doctors, lawyers and many other organizations. The essence of this system is that the employer gives the candidates a certain probation period and evaluates them at the end of the probation period. If the employee is not promoted, he must leave the unit. It is generally believed that the employment mode of "either promotion or leaving" for college teachers originated from American private universities, and it is an auxiliary operation rule of tenure.
