Occupational Disease in Swiss Insurance Law
Occupational disease is a health impairment caused primarily by the exercise of professional activity and not by an accidental event. Covered by the Federal Act on Accident Insurance (AAIA), occupational disease gives rise to the same benefits as a workplace accident, provided it is recognised by SUVA or the competent AAIA insurer. PBM Avocats represents sick workers in Geneva and Lausanne.
Statutory Definition and Conditions for Recognition
Art. 9 AAIA distinguishes two categories of occupational diseases:
- Listed diseases (art. 9 para. 1 AAIA): they appear in Annex 1 of the OAAIA. Proof of causation is presumed if the worker was exposed to the corresponding harmful agent. Examples: silicosis, lead poisoning (saturnism), occupational dermatoses, occupational hearing loss
- Unlisted diseases (art. 9 para. 2 AAIA): the disease must be caused exclusively or predominantly by the exercise of professional activity. The burden of proving causation lies with the insured person
Most Common Occupational Diseases in Switzerland
| Disease | Harmful agent | At-risk sectors |
|---|---|---|
| Silicosis | Silica dust | Mining, construction, ceramics |
| Mesothelioma (asbestos) | Asbestos fibres | Construction, insulation (before 1990) |
| Occupational hearing loss | Excessive noise (≥ 85 dB) | Industry, construction sites, music |
| Occupational dermatoses | Irritant substances, allergens | Healthcare, hairdressing, cleaning |
| Lead poisoning (saturnism) | Lead and compounds | Industry, glassware, recycling |
| Musculoskeletal disorders | Repetitive movements, vibrations | Offices, industry, handling |
Causation: The Central Issue in Litigation
Recognition of an occupational disease rests on demonstrating natural causation (the disease is effectively caused by occupational exposure) and adequate causation (this type of exposure is apt to cause this type of disease). SUVA may require:
- Evidence of exposure (safety data sheets, workplace hygiene measurements, colleague testimonies)
- Occupational medicine expert opinions
- Epidemiological data on the prevalence of the disease in the sector
The latency period often poses a particular challenge: for diseases with a long latency period (asbestos, silica), the worker may have left the exposing company decades ago. SUVA may still recognise the disease if the causal link is established.
Obligation to Report and Role of the Employer
The employer has an obligation to report occupational diseases to SUVA (art. 45 AAIA). This obligation also extends to the treating physician who diagnoses a potentially occupational disease. In case of doubt, SUVA mandates a physician specialising in occupational medicine to evaluate the occupational link.
In parallel, the employer is required to take preventive measures to eliminate or minimise harmful agents (art. 82 ff AAIA, Ordinance on the Prevention of Accidents and Occupational Diseases OPA). SUVA may impose protective measures and monitor their implementation.
Contesting a Refusal of Recognition
If SUVA refuses to recognise a disease as occupational, the avenues for contestation are identical to those applicable to accidents:
- Opposition within 30 days with SUVA
- Appeal before the cantonal insurance court within 30 days if the opposition is rejected
- Private or court-ordered medical expert opinions may be decisive in establishing occupational causation
What is the difference between an occupational disease and a workplace accident?
A workplace accident occurs suddenly and unexpectedly during professional activity. An occupational disease develops progressively due to repeated exposure to harmful agents in the workplace. Both are covered by the AAIA and SUVA, but the recognition rules differ: the occupational disease must appear on the SUVA list or be causally proved.
My disease does not appear on the SUVA list. Can I still obtain recognition?
Yes. Art. 9 para. 2 AAIA provides that unlisted diseases may be recognised as occupational if they are caused exclusively or predominantly by the exercise of professional activity. The proof of causation is, however, more difficult to establish. A specialist lawyer and specialist medical expert opinions (occupational medicine) may be necessary.
What is the latency period in an occupational disease?
The latency period is the time between exposure to the harmful agent and the appearance of symptoms of the disease. For certain occupational diseases (for example silicosis or asbestos-related mesothelioma), this period may exceed 20 or 30 years. SUVA may still recognise the occupational disease if the causal link is established, even long after the end of exposure.
Must my employer take measures if I am diagnosed with an occupational disease?
Yes. The employer has a statutory obligation to protect the health of their workers (art. 82 ff AAIA, OPA). In the event of an occupational disease, the employer must analyse the causes, implement preventive measures for the other exposed workers, and report the case to SUVA. SUVA may carry out on-site inspections and order protective measures.
What benefits does SUVA pay in the event of an occupational disease?
AAIA benefits in the event of an occupational disease are identical to those paid in the event of a workplace accident: coverage of medical costs, daily allowances (80% of salary), disability pension if the incapacity for gainful employment is at least 10%, survivors' pension for close relatives, and integrity compensation (IC) in the event of permanent after-effects.
