Through its decentralised structure, the union has focused on organising precarious workers, including in the country's logistics, care and cultural industries.

The 1988 Polish strikes, led by the Independent Self-Governing Trade Union "Solidarity" (NSZZ), ultimately culminated with the fall of Communism in Poland.

[2] The All-Poland Trade Union Workers' Initiative (Polish: Ogólnopolski Związek Zawodowy Inicjatywa Pracownicza; OZZIP) was established in 2001.

[4] The OZZIP's method of organising, which avoided the establishment of a trade union bureaucracy and eschewed formal relations with employers, proved attractive for some Polish workers.

[10] In 2011, employees of Monitor, an electronics assembly factory based in a special economic zone in Lower Silesia, began organising themselves into a union under the banner of Workers' Initiative.

Union activism was also restricted by the intensity of the work, so meetings took place in mornings, when workers had the time and energy to participate.

[20] As union campaigns over junk contracts coincided with that year's parliamentary elections, unions and political parties began to converge on the issue;[21] while Law and Justice (PiS) aligned itself with Solidarity, Left Together (Razem) aligned with the OZZIP's own campaign by calling itself the "Party of the Precariat".

[23] In 2011, the mayor of Poznań Ryszard Grobelny announced a wage freeze for nursery workers, which would remain in place until 2023.

The union has aimed to improve working conditions for domestic workers, by agitating for better wages and legal contracts.

[25] According to a report by CARE International, the OZZIP's campaign to raise awareness about the situation of migrant workers had a "significant impact" on the domestic labour sector.

Following the dismissal of a union activist and labour inspector in November 2021, OZZIP organised street protests against Amazon.

[29] Workers' Initiative is a multi-sector union, which participates in workplace organising in all grades of the private and public sector.

[35] It has formed links with anti-eviction groups and tenants unions, as well as the broader Polish anarchist and feminist movements.
