Occupational disease in Luxembourg: reporting, evidence and recognition
An illness may develop after prolonged exposure at work. However, recognition as an occupational disease requires a specific assessment. The file must explain both the diagnosis and the conditions in which the work was performed.
Distinguish disease from accident
The Accident Insurance Association describes occupational disease as the consequence of exposure to a risk or particular working conditions. An official schedule lists various diseases. A disease’s absence from that schedule does not exclude recognition altogether, but its occupational origin must then be proven. [1]
Describe how the situation developed rather than artificially searching for a single event. If a specific event also occurred, tell the doctor so the different possibilities can be examined without confusion.
The doctor’s role in reporting
According to the AAA, a medical report is made by the doctor where there are well-founded suspicions of a determining occupational cause. It includes medical evidence and information about risks. The AAA then gathers the necessary occupational information, particularly from the employer. The stated reporting deadline is one year from becoming aware of the occupational origin. [1]
Keep a copy of the report and its date. If you have had several employers or positions, prepare a chronology to help describe the exposure.
Document actual working conditions
Gather job descriptions, assignment periods and accessible information about duties. Identify products used, movements, constraints and protective measures according to the disease being assessed. Specify frequency and duration rather than phrases such as “very often” or “for a long time”.
Conditions may have changed during your career. Distinguish periods and do not describe an old position by its current organisation. If some documents are no longer available, identify people or departments likely to hold the information.
Follow the investigation and understand the decision
Respond to requests for further information, identifying the file and keeping a copy. If information from the employer appears inaccurate, explain the correction and its supporting evidence. Avoid sending conflicting versions of a chronology without explaining the amendment.
When the decision arrives, examine its precise reason: diagnosis, exposure, occupational link or another condition. A useful challenge addresses the point actually relied upon. It does not merely repeat that the illness arose during the employment period.
Is sick leave enough to establish an occupational disease?
Incapacity for work and occupational origin are different questions. The recognition file must specifically address that origin.
What if the employer has changed or no longer exists?
Prepare dates, known contact details and retained documents. Have the ways of documenting exposure assessed rather than abandoning the matter for this reason alone.
KM Legal can assist in organising employment documents and analysing an AAA decision, taking the medical assessment into account.
