The article addresses the problem of ‘authoritarian innovations’ in labour governance in Poland, understood as new government practices that maintain the semblance of social dialogue while limiting the influence of unions. Unlike most studies that analyse authoritarian practices since the right-wing Law and Justice Party came to power in Poland in 2015, this analysis takes a longer historical perspective. Drawing from Ost's thesis of ‘illusory corporatism’, it argues that a fundamental element of neoliberal transformation in Poland after 1989 was the introduction of weak tripartite institutions used to suppress social conflicts while complying with international standards. Based on documentary analysis and 37 expert interviews with social partners, the article shows how authoritarian innovations introduced in the 1990s have undermined worker participation and tripartite social dialogue in the context of two crises: the global financial crisis of 2008–12 and the COVID-19 pandemic of 2020–22. Comparing the role of social dialogue in shaping the responses of liberal and illiberal governments to these different external shocks, the analysis demonstrates the continuity and evolution of authoritarian innovations in labour governance in Poland and their implications for theoretical debates arounds corporatism.
