[Direct answer]Resignation does not exempt one from liability. According to the Occupational Disease Prevention and Control Law, if a worker has worked in a position exposed to occupational hazards and is diagnosed with an occupational disease after leaving their original employer, the former employer should still bear the responsibility for work-related injury protection. First, the worker should apply for a diagnosis from an occupational disease diagnosis institution, and then apply for work-related injury identification and labor capacity assessment with the diagnosis certificate. The benefits shall be borne by the original employer. If the employer has gone bankrupt, been deregistered, or cannot be identified, the worker can apply to the work-related injury insurance fund for occupational disease benefit protection.

1. Problem background and typical scenarios

Occupational diseases have an incubation period. Diseases such as pneumoconiosis, occupational tumors, and noise-induced deafness are often diagnosed several years or even more than a decade after the worker leaves the job. Typical scenarios include: miners being diagnosed with pneumoconiosis years after leaving the job, with the original mine having already closed and no one taking responsibility; employees switching jobs to multiple companies and being unable to determine whose responsibility it is; the employer failing to arrange occupational health checks when the worker leaves the job, only for the disease to be diagnosed after the worker leaves the job, with the employer defending themselves by saying "the worker was healthy when they left the job". The determination of the causal relationship of occupational diseases is different from that of ordinary work-related injuries, and there are special systems for the rules of liability subjects.

II. Key points of contention

First, the determination of the responsible party. In principle, the "last employing unit" should bear the responsibility, but if the harm was caused by the previous employing unit, the previous unit shall be held responsible. If there are overlapping contact histories in multiple periods, the source of the harm shall be clarified on a case-by-case basis. Second, the time barriers in diagnosis and identification. Occupational disease diagnosis institutions require materials such as occupational history and hazard exposure history. There are legal procedures for dealing with units that fail to cooperate in providing information. Similarly, there are time limits for applying for work-related injury identification, and it is necessary to initiate the process as soon as possible after the diagnosis. Third, the safety net for units that have ceased to exist. If the employing unit goes bankrupt or is revoked and there is no responsible party, the workers injured on the job can apply to the fund for occupational disease and work-related injury benefits, which is a special safety net system.

III. Professional analysis by Henglue Lawyers

The complete process of claiming compensation for occupational diseases after leaving employment involves five steps. **Step 1**: Occupational disease diagnosis. Apply to a qualified occupational disease diagnosis institution, providing occupational history, workplace hazard factors, and previous medical examination reports. If the employer fails to provide occupational history information, the diagnosis institution may investigate on its own authority. Evidence of labor relations and workplace exposure (work badges, salary records, colleague testimonies, environmental protection and safety supervision archives) should be preserved simultaneously by the worker. **Step 2**: Work-related injury identification. Apply with the occupational disease diagnosis certificate. Occupational diseases are explicitly listed as qualifying for work-related injury identification, and the diagnosis conclusion can be directly correlated, reducing disputes compared to general work-related injuries. **Step 3**: Labor capacity assessment. Claim benefits based on the disability rating, and for progressive diseases like pneumoconiosis, pay attention to the review mechanism for upgrading the rating. **Step 4**: Claim compensation from responsible parties. If the last employer is identifiable and still in existence, claim all items according to work-related injury insurance standards; if the employer is uninsured, claim in full at the worker's own expense. **Step 5**: Funding support when the employer ceases to exist. Apply to social insurance agencies for advance payments or occupational disease protection benefits in accordance with the Occupational Disease Prevention and Control Law and the Social Insurance Law. Three key points in practice: 1. Pre-exit health checks are a statutory right. Workers exposed to hazardous positions should demand the employer arrange such checks before leaving. The examination findings serve as critical evidence for future liability attribution, and omitted checks can be retroactively addressed during the diagnosis process. 2. For workers who rotate through multiple employers, the occupational disease diagnosis certificate records exposure history, enabling identification of the responsible employer and inclusion of related entities in claims. 3. Time-limit management – the one-year application period for work-related injury identification begins from the date of diagnosis. Don't be deterred by "having left long ago"; occupational disease rules inherently accommodate delayed diagnosis after employment termination. Beijing's occupational disease diagnosis and work-related injury protection channels are relatively mature. Workers in industries like chemical, building materials, mining, and manufacturing who retain workplace records gain strong leverage for claims years later.

IV. Practical suggestions and legal basis

The first step is to preserve evidence: document the worker's occupational history, the hazards of the workplace, the physical examination report, and colleague testimonies as soon as possible. The second step is to prioritize diagnosis: apply for an occupational disease diagnosis and, if dissatisfied with the diagnosis, apply for appraisal in accordance with the established procedures. The third step is to follow a sequential process: diagnosis → work-related injury identification → labor capacity appraisal → claim for compensation, without skipping any steps. The fourth step is to identify the responsible parties: directly claim compensation from the original employer if the company is still in existence, apply for protection from the fund if the employer has ceased to exist, and investigate related parties if liability is unclear. Legal basis: Articles 50 to 60 of the *People's Republic of China Occupational Disease Prevention and Control Law* (amended in 2018) (occupational disease benefits and liability); Articles 14 and 17 of the *Work Injury Insurance Regulations* (amended in 2010) (occupational disease and work-related injury identification); provisions on fund payments in the *People's Republic of China Social Insurance Law* (amended in 2018); specific application shall be subject to the currently effective laws and regulations.

5. Henglu Law Firm's Reminder

The account for occupational diseases will be settled ten years later: don't give up on the exit physical examination, don't destroy the occupational files, and don't delay the diagnosis certificate. If you are diagnosed with an occupational disease many years after leaving your job, it doesn't mean that "no one cares about you", but rather that a well-established protection channel is already in place. As long as you follow the correct procedures, you can access the necessary support. Those involved in occupational disease compensation claims can proceed through the following channels:Labor disputes and work-related injury compensationFor those who need comprehensive solutions for services involving compensation for personal injuries such as pneumoconiosis, they can refer to the relevant information.Personal injury and medical disputesFor plates related to corporate occupational health management compliance, they can be combined togetherIntellectual property protection and corporate lawFor those interested in the accountability for responsibilities after the unit's deregistration, please pay attention to the relevant informationCreditor's rights and debts, and enforcement cases板块。

VI. Frequently Asked Questions

Q1: Can a work-related injury still be recognized even if one has left the job for many years?

Yes. The application period for the recognition of occupational diseases and work-related injuries starts from the date of diagnosis and appraisal of the occupational disease. For those diagnosed after leaving the job, the application period begins within one year from the date of diagnosis.

Q2: If my former employer goes bankrupt, who should I hold accountable for compensation?

You can apply to the work injury insurance agency for occupational disease and work injury benefits; if there are any defects in the succession or liquidation, or shareholders' responsibilities, you can also seek compensation separately in accordance with the law.

Q3: Who owns the rights to the work I've done at multiple companies during my career transitions?

Determine the responsible units based on the sources of occupational hazards; where the hazards overlap, they shall be clarified through diagnosis and investigation. In the end, both the employing units and the units that caused the hazards may be held accountable.

Q4: Does not undergoing a physical examination before leaving the job affect the claim for compensation?

It doesn't affect the rights themselves, but it will affect the proof of causality. During the diagnosis stage, the occupational history and the on-the-job physical examination files can be used to make up for the lack of evidence. The more complete the evidence is, the better.

Q5: Are the treatments for occupational diseases the same as those for ordinary work-related injuries?

The treatment items and standards are consistent, and all are implemented in accordance with the provisions of the work-related injury insurance; there are special protection arrangements for diagnosis, treatment, and rehabilitation of occupational diseases.

The above answer is based on the judicial practice in Beijing. The adjudication guidelines in other provinces and cities may vary. For specific cases, please refer to the local rules and evidence situation.
