Insurers’ liability under worker compensation insurance is defined as per Common Law or the Workmen Compensation Act 1923 in case of occupational disease. According to the Act, an occupational disease is a disease that a worker may contract while in service of the employer. One has to prove that the disease contracted is related to the occupation of the worker to claim policy benefits. To receive compensation, the worker should be employed with the insured company for a minimum of 6 months. In that case, the insured has to pay compensation to the worker if a work-related disease is inflicted on him/her.
Key Takeaways
-
The 6-Month Rule: To protect employers from unfair claims, a worker must usually have completed at least six months of continuous service before they are eligible to claim for an occupational disease.
-
Aggravation is Covered: A major point of liability is “aggravation.” Even if a worker had a mild respiratory issue before joining, if the workplace fumes (like welding smoke) made it severe, the insurer must compensate them.
-
The Importance of Entrance Exams: As shown in the case study, companies that require a medical report at the time of joining have a much easier time verifying claims and protecting themselves from fraudulent pre-existing disease filings.
-
Timing of Wages: Compensation is calculated based on the worker’s salary at the time the disease leads to a claim or termination, not when the disease was first “contracted,” which often benefits the worker due to pay hikes.
-
Specific Sensitizing Agents: Occupational asthma is only covered if it is caused by recognized agents inherent to the work, such as flax, hemp, or specific chemicals used in the manufacturing process.
-
Documentation is Decisive: The claim settlement process relies heavily on the Doctor’s Report and a complete account of the ailment to ensure the illness is truly work-related.
Occupation disease falls under workmen compensation policy coverage
Certain occupational diseases falling under this policy are as follows:
- Bronchopulmonary disease caused by flax, hemp and sisal dust (Byssinosis)
- Skin diseases caused by physical, chemical or biological agents and
- Occupational asthma is caused by recognized sensitizing agents which are inherent to the work process.
The employer is also liable to pay compensation when a worker’s pre-existing disease aggravates due to work environment or work-related injury.
The insured has to compensate even though a worker had a disease prior to working with him. Wages are an important determinant of the compensation amount. The insurer considers the wages of the worker at the time of his termination from employment. The calculation of compensation does not take into account the date of contracting the occupational disease.
Case Study
For the last five years, Mr Jeevan Saran was working with T.S Electrical Company as a senior electrician. His job duty included welding different electrical parts.
However, for the past few months, he was experiencing breathing issues and constant coughing problems. When the situation deteriorated further, he went to his doctor for treatment. The blood test report indicated exposure to isocyanates, which develop in welding fumes— a well-known cause of occupational asthma.
The doctor prescribed some medicines and suggested one-week bed rest. Jeevan informed his manager about his medical condition. Jeevan took seven days’ leaves on request.
The manager advised Jeevan to approach the insurance policy to get workmen’s compensation. As his disease was an occupational ailment, it came under the purview of the workmen’s compensation insurance policy.
The conclusion from the case
In this case, Jeevan filed a claim under workmen’s compensation insurance. He asked the insurer to pay his medical expenses for asthma which occurred because of his occupation. The workmen’s compensation insurer asked for a complete account of the ailment along with the doctor’s report. To see if asthma-associated, with his job such reports were needed.
T.S Electrical Company always asks for a medical test report from its new employees to see if job applicants are physically fit for work. Jeevan also submitted a medical report at the time of joining the company.
The workmen compensation insurance company asked for their medical report of Jeevan, which he submitted at the time of joining the company. The insurer wanted to confirm that asthma was not a pre-existing ailment.
The HR division of T.S Electrical Company provided Jeevan’s medical report to the insurer.
Summary Table: Occupational Disease Coverage & Claims
| Feature | Statutory Requirement | Impact on Claim |
| Minimum Service | Worker must be employed for at least 6 months. | Prevents claims for diseases contracted prior to joining. |
| Causal Link | Must prove the disease is inherent to the work process. | Evidence: Requires medical reports linking toxins (e.g., isocyanates) to the job. |
| Pre-existing Conditions | Aggravation of an existing illness is covered. | Liability: Employer is liable if the work environment made the condition worse. |
| Wage Determination | Based on wages at the time of termination or claim. | Payout: Higher revised salaries result in higher compensation. |
| Common Ailments | Byssinosis, Occupational Asthma, and Skin Diseases. | Scope: Covers physical, chemical, and biological agents. |
| Verification | Comparison of “Joining Medical Report” vs. “Current Report.” | Validation: Ensures the disease developed during the course of employment. |
Now the insurer had all the important documents related to the claim, which its claim department thoroughly inspected and verified. The insurer agreed to settle the claim after ascertaining that the insured developed the ailment during working hours.
The insurer approached T.S Electrical Company to know the salary of Jeevan. At the time when Jeevan visited the doctor for the treatment, he was earning Rs 8,000/month. However, his salary increased to Rs 10,000/month at the time of reporting the claim.
Now, the workers’ compensation insurance company considered the revised salary of Jeevan, i.e., Rs 50,000 and settled the claim on the basis of it.
Frequently Asked Questions (FAQs)
1. What exactly qualifies as an “Occupational Disease”?
A) It is a health condition that a worker develops specifically because of the nature of their job. Examples include Byssinosis (from hemp/flax dust), Occupational Asthma (from chemical fumes), or chronic skin diseases caused by handling biological agents at work.
2. If a worker already had asthma before joining my company, am I still liable?
A) Yes, if the work environment aggravated the condition. If your workplace contains “sensitizing agents” that made the worker’s pre-existing asthma worse, the law holds the employer responsible for the resulting medical expenses and disability.
3. Why did the insurer ask for the medical report from when the employee first joined?
A) This is done to establish a “baseline.” By comparing the health of the employee at the time of hiring versus the time of the claim, the insurer can verify that the disease was indeed contracted or significantly worsened during their tenure with your company.
4. How is the compensation amount calculated for a disease that takes years to develop?
A) The calculation is based on the worker’s wages at the time of the claim or termination, not when the symptoms first started. This ensures the compensation reflects the worker’s most recent earning capacity.
5. Is there a minimum time a worker must stay with the company to file an occupational disease claim?
A) Yes. Under the Act, a worker generally needs to be employed with the company for a minimum of 6 months to be eligible for compensation related to an occupational disease. This helps ensure the disease is actually linked to the current workplace.
