A chronic degenerative disease of the central nervous system, multiple sclerosis (MS) affects around 100,000 adults in France, predominantly young women. Non-fatal in the short term, the average age of onset of MS is between the ages of 20 and 40, and results in job reten¬tion difficulties in the long term. Persons with MS can benefit from the long-term illness (LTI) scheme (Dispositif "Affections de Longue Durée", ALD), which entirely covers the patient's contribution to expenses related to the pathology and provides entitlement to additional benefits in the event of sick leave.
Based on a representative sample of French employees, using professional career data from the beginning of their careers until 2015, we compared the professional development as well as the salaries and replacement income linked to the professional activity (unemployment benefit, sick pay, and disability pension) of persons with MS who were beneficiaries of the long-term illness (LTI) scheme with those of the rest of the working population. The results show that despite a favourable employment situation at the time of recognition of a chronic condition, one out of two people had a disability ten years later and the salary level, which was high before the onset of the disease, fell below the median income threshold two years after the administrative recognition of a chronic condition due to sick leave. This decrease in income was partly compensated by replacement income.
