What's the difference between the contract workers recruited by public institutions and the prepared wages?

This situation is extremely common now, that is, the so-called "old methods for the elderly, new methods for the new." Old comrades in the past all belong to the latter-employees with staffing usually have no contracts. In recent years and beyond, newly recruited employees among regular employees must sign employment contracts when they join the company.

There will be no difference in wages between the two. After all, they are all formally established employees. They all pay wages and benefits according to the regulations of the state or units, and are promoted under the same standard. The difference is that old employees are more stable, and some institutions allow old employees to return to their offices after retirement and enjoy the retirement benefits of civil servants. Personnel files are generally kept by higher authorities. New employees are relatively unstable. After retirement, they are all co-ordinated by the society, and personnel files are generally kept by their own units. Of course, although a new employee signs a contract, it will be renewed after the contract expires, so although it is relatively unstable, it is actually quite stable.
