 Seeing that the new version would establish Moldovan as the only official language of the MSSR, activists from a number of Tiraspol factories came together to create the United Work Collective Council ("Ob"edinnennyi Sovet trudovykh kollektivov", OSTK) and called an immediate strike that eventually led to the shutdown of most major industrial activity (concentrated in the Transnistrian region) throughout the SSR.The peak of the strike movement came in September 1989 in the immediate aftermath of the MSSR Supreme Soviet's passage of the language legislation.Vladimir Socor, analyst for the Radio Free Europe/Radio Liberty, places the total number of strikers in the MSSR at close to 200,000, writing, "By August 29, when the session of the Moldavian Supreme Soviet convened, more than 100,000 workers and employees at over 100 enterprises were on strike in the republic; their numbers almost doubled within four days.” This level of mobilization was not long sustained.
