Can the last person in the social security account be reduced and one person added at the same time?

The last person in the social security account can reduce one employee and increase one person at the same time.

Most of the increase in social security will take effect next month, that is, the fee will be deducted next month; The reduction of staff in that month will also take effect next month, so the fee will continue to be deducted in that month.

Some people take the fifth day of each month as the demarcation point. For example, the addition of personnel before the 5th of the current month can be counted as effective in the current month, and the expenses will be deducted in the current month. The reduction of staff before the 5th of that month can be considered as effective last month, and the insurance has been stopped last month, so there is no need to pay for it in that month.

I still have to remind you that local policies and time divisions are not uniform, and you still need to consult yourself.
