First of all, it is certain that it is against the law for the employer to ask you to sign a blank contract and not to keep the text of the contract. According to Article 16 of the "Labor Contract Law of the People's Republic of China": "The labor contract becomes effective when the employer and the employee negotiate and reach an agreement, and the employer and the employee sign or stamp the labor contract text. Article 8 takes effect. The employer and the employee shall each hold a copy of the labor contract text. "Article 81: "The labor contract text provided by the employer does not specify the labor contract requirements stipulated in this law. If the employer fails to deliver the labor contract text to the employee, the labor administrative department shall order it to make corrections; if it causes damage to the employee, it shall bear liability for compensation." Article 86: "Liability for labor contracts that are confirmed to be invalid. If a labor contract is confirmed to be invalid in accordance with Article 26 of this Law and causes damage to the other party, the party at fault shall be liable for compensation.” Therefore, if you find that the terms of the labor contract are not favorable to you, you can request to confirm that the labor contract is invalid. You can claim compensation for the losses caused to you.

Secondly, regarding the issue of overtime pay, it is also against the law for the employer to pay according to the minimum standard. It should be based on dividing the amount of salary you actually receive every month by the actual number of hours you work, and the hourly overtime pay shall prevail.

Finally, regarding how to protect your rights, you can first negotiate with the employer. If the negotiation fails, apply for labor arbitration to the local labor arbitration committee or file a complaint with the labor inspection brigade. If you are not satisfied with the labor arbitration, you can also file a complaint with the court. File a lawsuit. In labor disputes, the employer is responsible for providing evidence, but you must provide certain evidence for overtime pay.
