Many Spaniards who come to work here assume that "accident insurance" covers any health problem related to work. That confusion can be expensive. The Federal Accident Insurance Law (LAA) distinguishes two clearly separate categories: the accident, which is a sudden, external and involuntary event, and the occupational disease, which is a pathology caused mainly by work activity. The difference is not semantic: it depends on who pays, how much and for how long.
For the SUVA to recognize a disease as occupational, it must be caused by work in more than 50% in the case of diseases included in the official list, and in more than 75% for those that are not. Ailments derived from continuous noise, certain skin allergies, respiratory pathologies due to exposure to toxic substances, or musculoskeletal diseases related to work postures can fall into that category, but recognition is not automatic and the process can last months. During that time, many workers find themselves in a gray area that no one had explained to them.
The real problem appears when the SUVA determines that the labor cause does not meet the required threshold. In this case, the illness becomes the responsibility of the medical insurance (LAMal), which covers medical costs but does not guarantee any salary replacement. Financial compensation during sick leave then depends on the individual contract and whether the employer has contracted daily compensation insurance (LCA), which is not mandatory in Switzerland.
The most important thing to know: if you suspect that a health problem has its origins in your work, notify your employer as soon as possible and demand that they declare it to the SUVA as a possible occupational disease. Limitation periods exist, and once passed, recovering those rights becomes practically impossible. The employer has the obligation to make the declaration, but you can also request it directly.
