What if there is no social security at work?

If your personal file is still in the original unit, then your personal social security relationship is also in the original unit, but you are not working in the original unit. In this case, if you want to retire, you must go back to the original unit for retirement, because the social security relationship is in the original unit and you can only retire through the original unit.

Of course, this situation still exists in society. Generally speaking, a promise made by large state-owned enterprises in order to buy out employees is to buy social security for their original employees, so this phenomenon has formed, which is of course good for employees themselves, because after all, if they pay social security fees themselves, it is also a big expense every year, and there is no need to pay this fee themselves.
