Jeunesse ouvrière chrétienne
The Young Christian Workers (YCW; ) is an international organization founded by Rev. Joseph Cardijn in Belgium as the Young Trade Unionists; the organization adopted its present name in 1924. Its French acronym, JOC, gave rise to the then widely used terms "Jocism" and "Jocist". In 1925, the JOC received Papal approbation, and in 1926 spread to France and eventually to 48 countries.
