The aim of the project is to update the list/code list of posts subject to an increase in insurance periods and to establish a more recent version of the list of workplaces where work is particularly difficult and harmful to health, or where, due to the nature and weight of work, workers are no longer able to perform their work successfully after certain years of age (professional activities) and thus prepare the professional basis for decision-makers (the competent ministry) in setting up a more balanced occupational insurance scheme.
