Legal analysis: in civil litigation such as labor relations, whether the labor contract is signed for the first time or renewed, the signature of the parties is a sign of their legal agreement and acceptance of the rights and obligations of the contract. The signatory shall be responsible for the possible legal consequences of his actions. If someone else signs the contract, it should be entrusted by the parties in writing or ratified afterwards, otherwise, the contract is not legally binding on the parties. If I know that someone else has committed a civil act in my own name, and I don't deny it, it will be regarded as consent. At present, some employers and workers do not take the formal requirements of labor contracts seriously in the process of implementing the labor contract system, and sometimes they miss signing or sign on their behalf, which has triggered a series of labor disputes. Therefore, don't neglect the procedure of concluding a labor contract, don't sign a contract on behalf of others without authorization, and don't entrust others to sign a contract at will.

Legal basis: Article 490 of the Civil Code of People's Republic of China (PRC). If the parties enter into a contract in the form of a contract, the contract shall be established when the parties sign, seal or press their fingerprints. Before signing, sealing or fingerprinting, one party has fulfilled its main obligations, and the contract is established when the other party accepts it. A contract shall be concluded in written form as stipulated by laws, administrative regulations or agreed by the parties. If the parties do not do this in writing, but one party has fulfilled its main obligations and the other party accepts it, the contract is established.

Article 500 of the Civil Code of People's Republic of China (PRC) shall be liable for compensation in case of any of the following circumstances in the process of concluding a contract: (1) concluding a contract through malicious negotiation; (2) Deliberately concealing important facts related to the conclusion of a contract or providing false information; (three) there are other acts that violate the principle of good faith.
