Labor Contract Law
Article 26 The following labor contracts are invalid or partially invalid:
(1) Causing the other party to conclude or change a labor contract against its true meaning by means of fraud, coercion or taking advantage of the danger of others;
(2) The employer exempts itself from legal liability and excludes the rights of workers;
(3) Violating the mandatory provisions of laws and administrative regulations.
Any dispute over the invalidity or partial invalidity of a labor contract shall be confirmed by the labor dispute arbitration institution or the people's court.
Article 27 If part of a labor contract is invalid and does not affect the validity of other parts, the other parts are still valid.
Article 28 If the labor contract is confirmed to be invalid and the laborer has already paid the labor, the employer shall pay the laborer the labor remuneration. The amount of labor remuneration shall be determined with reference to the labor remuneration of workers in the same or similar positions in the unit.
