When the employer does not pay social security, if you want to solve the problem through arbitration, here are some suggestions and steps:1Gather evidence: First, if you do not have an employment contract, you need to collect some evidence that can prove the existence of an employment relationship between you and the employer. This may include payroll records, clock-in records, work group chat records, and more. This evidence can help you prove the employment relationship between you and the employer, and provide strong support for subsequent arbitration. 
2.Communicate to resolve: Before taking legal action, you can try to communicate with your employer to understand why they are not paying social security and try to reach a mutually acceptable solution. If communication doesn't work, you can consider taking the next step. 3.Submit a Notice of Forced Separation: If you decide to resolve the issue through arbitration, you can issue a Notice of Forced Separation to your employer. In this notice, you need to clearly state the reasons for your resignation, including the employer's non-payment of social security. This notice can be used as one of the grounds for your application for arbitration. 
4.Submit a Request for Arbitration: Submit your Request for Arbitration to your local labor arbitration commission. In the application, you need to provide detailed evidence and a description of the situation, including your personal information, employment relationship with the employer, and the employer's non-payment of social security. 5.Wait**: Once your arbitration application is accepted, you will need to wait for the Labor Arbitration Commission to arrange a time. At **, you are required to provide evidence and a statement of the situation to the arbitration committee and answer the questions of the arbitration committee. 
In general, if you want to resolve the issue of non-payment of social security by your employer through arbitration, you need to be fully prepared, collect sufficient evidence, and follow the legal procedures. During the arbitration process, you need to remain calm and rational and respect the outcome of the arbitration committee's award.
