How can I sue if I haven't paid social security for one year?

Legal analysis: report to the social security agency and sue the employer. Workers can choose three ways to protect their rights: 1. To terminate the labor contract on the grounds that the unit violates the law and demand to pay economic compensation. 2. If the failure to pay social security according to law causes losses to the workers, the employer may be required to compensate for the losses. 3. Report to the social security agency and ask the employer to pay back the social security.
