Who will bear the social security during the unpaid leave?

Personal commitment or company commitment. After leaving the job without pay, personal social security expenses such as "five insurances and one gold" should be borne by the individual. "Leave without pay" personnel engaged in other income-generating labor, in principle, should pay the labor insurance fund to the original unit on a monthly basis, and the amount is generally not less than 20% of my original standard salary. If it is stipulated in the agreement that individuals will pay insurance during the period of unpaid leave, then the contents of this agreement are binding on both parties, and the unit can stop paying insurance accordingly. If there is no agreement, the unit shall continue to bear the part stipulated by law. Therefore, during the period of unpaid leave, social security is borne by individuals or companies.
