Udarnik

Udarnik (Russian:уда́рник;IPA: [ʊˈdarnʲɪk]) is an East Slavic and Yugoslavian term for a superproductive worker in the Soviet Union and the other ex-communist countries. The term is derived from the expression "udarny trud" for "superproductive, enthusiastic labour", which is often translated as strike labour (udar "shock, strike, blow"), and udarnik as strike worker, respectively.
