Is there a relationship between social security and seniority?

Length of service refers to my working time with wage income as the whole or main source of income. If you work in party and government organs and institutions, seniority is the main basis for promotion and salary. If you work in an enterprise or freelance, it only involves the starting time or payment period of participating in various social insurances.
