Does retirement count as length of service when the unit didn't pay social security before?

Legal analysis: the work experience without paying social security cannot be regarded as the length of service, and the calculation of the length of service generally refers to the time of paying old-age insurance. Length of service refers to the working time when employees take wage income as their whole or main source of livelihood. The length of service marks the length of time employees have been working, and also reflects their contribution to society and enterprises, as well as the level of knowledge, experience and technical proficiency. When calculating the general length of service, it should include the length of service of the enterprise, but it should not include the general length of service when calculating the continuous length of service. Generally speaking, if you work intermittently for personal reasons, the working time before the interruption can only be calculated as general length of service. At present, when determining the insurance benefits of employees and whether they have retirement conditions, they generally only use continuous service. So the average length of service has lost its meaning today. After the implementation of the basic old-age insurance individual payment system, the actual payment period is taken as the basis for retirement and old-age insurance benefits, and the previous continuous service period is regarded as the payment period. The working years or continuous calculation years are calculated according to the provisions of national documents, that is, one year is counted as one year.

Legal basis: Article 72 of the Labor Law of People's Republic of China (PRC) determines the sources of social insurance funds according to the types of insurance, and gradually implements social overall planning. Employers and workers must participate in social insurance and pay social insurance premiums according to law.
