Youth work
Youth work actions were organized voluntary labor activities of young people in the Socialist Federal Republic of Yugoslavia. The actions were used to build public infrastructure such as roads, railways, and public buildings, as well as industrial infrastructure. The youth work actions were organized on the local, republic, and federal levels by the Young Communist League of Yugoslavia, and participants were organized into youth work brigades, generally named after their town or a local national hero. Important projects built by youth work brigades include the Brčko–Banovići railway, the Šamac–Sarajevo railway, parts of New Belgrade, and parts of the Highway of Brotherhood and Unity, which stretches from northern Slovenia to southern Macedonia.
