Hello, if you want to prevent the company from maliciously modifying the terms of the contract, you should refuse to sign such a contract, and even if you sign it, you should keep a copy of it yourself to prevent risks. In addition, regarding the double compensation for the unsigned contract, if the company does not affix its official seal or the person in charge of the company does not sign it, the contract lacks the necessary formal requirements in law, which should be regarded as the unsigned written labor contract and can claim compensation.
