Is it reasonable for the boss to pay 420 and the employee to pay 458 after the social security is increased?

Obviously unreasonable, it is correct to pay according to the proportion of the website. Now the boss has passed the pressure on to you, and you have borne the social security part that should have been borne by the company for the company.

You can ask the company for a salary slip first to see if the social security is deducted. If it is the part that you should not bear, you can communicate with the company and ask the company to refund the amount of social security that you overpaid.

However, it is a very necessary step to judge whether it is as you think. In addition, it also proves that the behavior of the unit is really unreasonable and illegal.
