 Article 10 of the Labor Law of the People's Republic of China stipulates that a written labor contract shall be concluded when establishing a labor relationship. If a labor relationship has been established but a written labor contract has not been concluded at the same time, a written labor contract shall be concluded within one month from the date of employment. If no labor contract is concluded, of course, workers can apply to the labor arbitration committee for labor arbitration. If they are not satisfied with the labor arbitration award, they can sue the people's court, that is, they can sue the company if they do not sign a contract at work. However, when the laborer sued the unit, because the two parties did not sign a labor contract, it was impossible to clarify the labor relationship. Workers need to actively collect evidence materials to prove the existence of labor relations with the unit. For example: work card or work card (preferably stamped by the employer), payroll card transaction record, payroll, tooling with company name, personal tax payment certificate printed and stamped by the local tax bureau, temporary residence permit handled by the employer for the worker, attendance record, social insurance payment record, work assignment form, colleague testimony (for those who leave the job) Audio and video recordings or other written materials with the name and official seal of the worker or the signature of the boss. According to Article 10 of the Labor Law of the People's Republic of China, a written labor contract shall be concluded to establish a labor relationship. If a labor relationship has been established but a written labor contract has not been concluded at the same time, a written labor contract shall be concluded within one month from the date of employment. If an employer and a worker conclude a labor contract before employment, the labor relationship shall be established from the date of employment.
