The United Work Collective Council (Russian: Объединённый Совет трудовых коллективов, romanized: Obedinyonnyy Sovet trudovykh kollevtivov) is an organization which led a political movement for the independence of Transnistria (also called Pridnestrovie) from the Republic of Moldova.
"Work collective councils" (Советы трудовых коллективов—STKs) were created throughout the Soviet Union in 1987 with the "Law on State Enterprises" as part of the perestroika reforms.
When the Supreme Soviet of the Moldovan SSR proposed establishing Moldavian as the official language of the republic, at first with Russian as a coequal official language and later without, activist industrial leaders and workers used the STKs as a forum for discussion of the legislation and exploited the institutional structure of the STKs to take control of Moldovan industry.
Using institutional resources and popularity acquired during the strike campaign, OSTK activists worked to get sympathizers elected to office, both on local and republican levels.
In Tiraspol, Igor Smirnov, later the president of the Pridnestrovian Moldavian Republic, was able to handily defeat the Communist Party candidate for the position of chairman of the city Soviet.
