Sécurité sociale

• The Family branch (Caf) helps families in their daily life and develops solidarity with vulnerable people.

• The Sickness branch (Cpam, Carsat, etc.) allows everyone to seek treatment according to their needs.

• The Work accidents-occupational diseases branch (Cpam, Carsat, etc.) manages the occupational risks faced by workers.

• The Pensions branch (Carsat, Cnav, etc.) pays pensions to retirees in Industry, services and commerce. It follows employees throughout their careers and helps them prepare for retirement. The Collection branch (Urssaf) which, unlike the others, does not manage a risk but collects contributions and social contributions to redistribute them for the benefit of other branches.
•  In addition to this general scheme (which covers nearly 90% of the population), there are other social security schemes, depending on the sector of activity to which you are attached.
•  We can cite the specific scheme for farmers (MSA) or special schemes, in particular for employees of large public enterprises. They cover the same risks, but not always in the same way.
