Need to write a statement

It's no use. Any statement or promise or agreement similar to giving up social security is invalid. Because paying social security is the legal obligation of enterprises.

Commercial insurance cannot replace social security.

If found, it will be fined and reissued.

There are several employees from other provinces in our company. Without our social security number, we can't pay them if we want to. Even in this case, I called the Labor and Social Security Bureau and got the answer "Then don't use this kind of person", or I will be fined.

The measures you take to make a statement or reach an agreement are no better than those that do nothing. As long as the workers go back on their word and apply for labor arbitration, those statements have no legal effect. Perhaps, workers do not understand, because it is possible to give up their rights on their own because of this statement.

There is no absolutely effective method. You know, social security funds are short of money, and they will try their best to make units and individuals pay, and any way to avoid handling social security is blocked.
