With the development of society and the change of job market, there are increasingly more people liking to change their jobs. Concerning this phenomenon, people have different attitudes. Some people would like to insist on doing one job in one work unit, because they think that the longer they work in a position, the more experience they will get and the more skillful they will be. However, the others tend to change their jobs frequently, because they think change is a good way to improve.
