Is the length of service calculated by file or social security?

According to the current human resources and social security policy, you should take part in social endowment insurance before you start working, and the calculation time of length of service is the same as the time when you start paying social insurance. Working years are calculated according to the years of paying social insurance. In fact, there is no provision for working years, which is calculated according to the payment. The payment period is changed to the original working period. If it is not paid, the payment period will not be calculated. Retirement is also calculated according to the payment period. No matter where your certificate is, it doesn't count if you don't participate in endowment insurance.

Notice on further standardizing the work of determining the length of service

When accepting the determination and change of length of service, counties (cities) should strictly follow the requirements of the document (No.49 [2005] of Zi Han, a new labor agency), that is, the identification of the identity and length of service of "state-owned employees" in cities and towns: all employees belonging to organs, institutions and state-owned enterprises occupy the labor plan index or cadre recruitment index of the original unit, are formally approved by the labor and personnel administrative department at or above the county level, and go through the recruitment procedures. After the employees pay insurance according to the specified time, (If the fees are not paid according to the provisions of the state, they shall be paid back. Employees of state-owned enterprises in the autonomous region began to pay endowment insurance premiums from 1993). Managers and demobilized veterans transferred to "large collective enterprises" or "small collective enterprises" can be recognized as "state-owned employees" in principle.

Identification of the identity and length of service of "large collective workers" in cities and towns: Any worker who works in a large collective enterprise, accounts for the recruitment index issued by the Planning Commission or the labor (personnel) administrative department, and the labor and personnel administrative department handles the recruitment procedures shall be identified as "large collective workers". The calculation of insurance payment and payment period of "large collective employees" can be handled with reference to "employees with labor contract system under ownership by the whole people". (New Lao She Line Word [200 1] 18 1)

Identification of "temporary workers": those who work in "small collective enterprises" (except state-owned managers) or "large collective enterprises", but the form of employment is self-recruited by the unit and does not occupy the recruitment (recruitment) index issued by the labor and personnel administrative department at or above the county level, should be identified as "temporary workers". Calculate the actual payment period from the date of participating in the basic endowment insurance. (No.46 [2000] of New Labor Society and No.49 [2005] of New Labor Society)
