The conclusion and modification of labor contracts shall follow the principles of equality, voluntariness, and consensus through consultation, and shall not violate the provisions of laws and administrative regulations. A labor contract signed in accordance with the law is immediately legally binding, and the parties must perform their obligations under the labor contract.
