What do you mean that employees recruited by public institutions in the form of personnel agents are temporary workers?

Units or organizations without personnel management authority entrust government personnel service agencies to conduct personnel management for probationary personnel. It is characterized by the separation of use and assessment from personnel file management and social security management. The disadvantage is that no one may be responsible for collecting the annual assessment files, and the personnel files are incomplete.

You are not a temporary worker, but you have not signed a contract with a public institution, and your bonus and welfare may be affected.
