Can social security be increased in the same month when the number of employees decreases?

Legal analysis: Yes. Generally speaking, after the successful reduction of social security staff, the social security status is displayed as interrupted, and the procedures for increasing staff can be handled immediately. Take Beijing as an example. You can find the interruption after shrinking for one and a half hours, and then you can add it, which will take effect immediately. However, the time is definitely different from place to place, and everything is subject to local regulations. The monthly date of 1-5 stipulates the maintenance time of the social security online application system, and it will be withheld after the 25th of each month. If we don't increase the staff before 25th, we won't be able to catch up with this month's withholding. The increase or decrease of personnel declared before 25th of the current month will take effect in the current month, and the increase or decrease of personnel declared after 25th can only be counted as next month.

To ensure citizens' right to receive material assistance from the state and society in accordance with the law in cases of old age, illness, work injury, unemployment and maternity.
