What proof do employees write if they don't go to social security?

Hello, you need to write a commitment letter of voluntary non-payment of social security, explaining the reasons why you are unwilling and the possible consequences you are willing to bear, paying special attention to the fact that this is voluntary, not forced by the company. Of course, it also includes some basic information about you.

PS: It's better to advise you to participate in social security. Don't care about a month's money. If you join the social security company, you will also pay part of the expenses, which will be good for your future illness and pension. Buying social security is more practical, which also means that you are guaranteed. Nowadays, the new loan policy requires individuals to show proof of social security payment for more than one year.
