Legal analysis: Effective. If the labor contract is signed without a date, the unit should be required to complete the relevant elements of the contract. If the contract does not include a date, but both parties have signed it, it is still a valid contract. If the company refuses to handle it, it can be regarded as an open-term labor contract and wages will be paid according to the contract. If you have not joined the company one month before the date, if you want to resign, you must apply to the company one month in advance. A labor contract is valid if it is only signed but does not include a date. The labor contract takes effect from the date it is signed by both parties. As long as the name is written by the employee himself, it is valid. Because the employee does not write a date, it can easily be exploited by the employer.

Legal basis: "Labor Contract Law of the People's Republic of China" Article 16 The labor contract shall be negotiated between the employer and the employee, and shall be signed by the employer and the employee on the labor contract text. Or stamp it to take effect. The employer and the employee each keep a copy of the labor contract text.
