Abandonment of service for just cause

Just cause is such which follows from: 1. The need to fulfill legal obligations, which are not compatible with the continuation of service; 2. Manifest danger of any damage or considerable ill; 3. Non fulfillment on the part of the employer of the obligations by which he is bound towards the workman; 4. Illness which prevents the workman from fulfilling his service; 5. Change of residence by the employer to a place which is not convenient to the workman.
