The Shock worker of Communist Labour was an official title of honour awarded in the Soviet Union to those who displayed exemplary performance in labour discipline (udarniks). It was awarded with a badge and certificate, as well as a cash prize.
The title of shock worker ('udarnik') had existed at least since the 1930s. However, its promotion was developed in the 1950s as part of a competition in honour of the XXI Congress of the Communist Party of the Soviet Union, to encourage a communist attitude towards work and the creation of the material-technical basis for the development of communism and education towards a communist society.
It was also awarded through the Komsomol - The
Young Communist League.
