The movement was responsible for the organization of Black Monday, a protest action, involving various forms of strike, that took place simultaneously in 147 Polish cities, towns and villages.

[10] A few years later, in 2020, Suchanow published a book, This is War,[11] in which she describes the origins of the OSK and the International Women's Strike, known in Spanish as Paro Internacional de Mujeres.

On 4 October 2017, following protests organised by OSK, police raided the offices of the Women's Rights Centre and Baba in Warsaw, Gdańsk, Łódź and Zielona Góra.

Marta Lempart, head of OSK, described the raids as "abuse of power" that disrupted the women's work by the confiscation of computers and documents.

[13] On 27 October, on behalf of OSK and proposals from citizens, stated that the aims of the protests included a return to the rule of law:[14] On 28 October 2020, Suchanow stated that the initial involvement of OSK in the protests was to defend women's own rights, not to remove the government.

[7] Suchanow, who had been injured by the police during protests in earlier years, leading to a spinal operation, interpreted a speech by Jarosław Kaczyński as a refusal to withdraw the Constitutional Tribunal ruling and an encouragement of escalation of violence.
