How to calculate the length of service of rural doctors after they are recruited as regular employees? Can you increase the length of service?

According to what you said, this is your local land policy, and it is useless for you to find a legal basis.

First, before being officially hired, although he is a temporary worker, according to the law, he should still sign a formal labor contract.

Second, according to the law, no matter where you work, the length of service is calculated cumulatively.

III. Supplementary Notice of the State Council on Several Issues Concerning the Retirement and Calculation of Working Years of State Organs;

Temporary staff employed by state organs (some called "employees") can be counted as working years after formal employment and before formal employment.

So your company's practice is obviously illegal, but what can you do as an employee? Complain to the labor inspection brigade? Apply to the labor dispute arbitration committee for arbitration or bring a lawsuit to the people's court? This kind of thing is not realistic and operability is not strong. You'd better wait until your job is stable. You can report this situation to the local commission for discipline inspection and the local government office, and of course you can also report it to the next higher health planning commission. This local strategy of your system is obviously illegal. Governing the country according to law will be useless there.
