The Free Workers Youth (Freie Arbeiter:innen Jugend) FAJ is the youth organization of the FAU Switzerland. Just as there are branch syndicates, there should also be a vessel in which young people can exchange ideas and be active together. The FAJ is self-determined by the FAU in its decisions and strategies.

Membership in the FAJ is possible up to the age of 25 and then ends automatically.

Members of the FAJ are automatically also members of the FAU
