Legal analysis: This means that you terminate the labor relationship with the unit you are currently working for and sign a contract with another unit. The labor contract can be re-signed, but it should be clearly stipulated that the subsequent unit will inherit the employee's working years with the original employer and related rights and obligations. If the labor contract is changed through negotiation, it will be inconvenient to manage the personnel files of the two units.
Legal basis: Article 490 of the "People's Republic of China and Civil Code" Where the parties conclude a contract in the form of a contract, the contract is established when both parties sign, seal or fingerprint. Before signing, sealing or fingerprinting, one party has performed its main obligations and the contract is established when the other party accepts it.
Laws and administrative regulations or the parties agree that a contract should be concluded in writing. If the parties do not use writing but one party has performed its main obligations and the other party accepts it, the contract is established.
