Law of the Peoples Republic of China on Prevention and Control of Occupational Diseases (effective since December 29, 2018), Article 33

When signing labor contracts (including employment contracts for public services) with its employees, an employer shall truthfully inform its employees of the occupational disease hazards which may arise in the work process, the consequences thereof, the protective measures against occupational diseases, remuneration, and other matters and include the same in the labor contracts; and shall not conceal such information or defraud its employees.

Where any employee conducts operations causing occupational disease hazards not included in the labor contract signed for any change of position or specific work during the contract period, the employer shall perform its obligation to truthfully inform the employee of such hazards as described in the preceding paragraph and modify the relevant clauses of the original labor contract.

Where the employer violates the provisions of either of the preceding two paragraphs, the employee shall be entitled to refuse to conduct operations causing occupational disease hazards, and the employer shall not therefore rescind the labor contract signed with the employee.
