1981 warning strike in Poland

The 1981 warning strike in Poland was a four-hour national warning strike that took place during and in response to the Bydgoszcz events. There, in the early spring of 1981 in the Polish People's Republic, several members of the Solidarity movement, including Jan Rulewski, Mariusz Łabentowicz, and Roman Bartoszcze, were beaten by the security forces, including Milicja Obywatelska and ZOMO. The Bydgoszcz events soon became widely known across Poland, and on 24 March 1981, Solidarity called for a nationwide strike in protest against the violence.
