What's wrong with the endowment insurance?

Legal analysis: if the original unit does not reduce staff, the new unit will not be able to increase social security for you. In this case, you can communicate with the original unit first and ask the HR of the original unit to reduce the number of employees for you. If the unit refuses to go through the formalities of downsizing, it can apply for labor arbitration, and the individual can go to the social security counter on his own with a court judgment or a ruling from the labor department (the judgment or ruling must have provisions to terminate labor relations). If the old-age insurance owed by the original work unit can't be made up, then you can't join the new work unit. At this time, I suggest you directly apply for labor inspection to solve such disputes. If the original unit fails to pay social security normally during the labor contract period, the labor inspection department will issue relevant notices, requiring the enterprise unit to pay employees' personal social security benefits within a time limit.
