Help! About the problem that the company paid social security for three years and only found it online for three months, please give some advice from professionals. thank you

Definitely not refundable. This is the welfare you should enjoy.

This is definitely against the rules.

It can be seen that the employer is extremely irresponsible.

You don't have to worry, you can use the law to protect yourself. According to the relevant provisions of the Labor Law, employers must sign labor contracts with employees and buy insurance, so they need to buy social security, which is compulsory insurance. Therefore, you can negotiate with the employer to solve it. If there is no result, you can apply for labor arbitration or report a complaint to the local labor and social security department, and bring a lawsuit to the local court, which can be effectively solved.

The evidence is to prove the existence of labor relations with the unit, such as salary slips and work cards.

Generally, you have to pay back the month you owe.

Insured by the unit, with the actual salary as the payment base.
