In this introduction to the Special Forum we seek to explore the possibilities for challenging labor unfreedoms through exercising solidarity. We critique the prevailing framings and dominant politics of 'combatting modernday slavery' -or what we refer to here as contemporary abolitionism.We argue that questions of coercion, control, and confinement are nonetheless increasingly pertinent to the analysis of contemporary labor relations and labor regimes. This leads us to reflect on how we might better conceptualise the many forms of unfreedom that are imposed on working people. We then explore the possibilities for a liberatory politics of solidarity that might challenge such unfreedoms. Finally, we summarise how the articles in the Special Forum engage with existing debates, and point us in new and fruitful directions for the task of confrontingintellectually and politically -the ways that contemporary labour relations are variously structured by unfreedoms.* Contemporary abolitionism, which we critique here, should not be confused with 'abolition geography' that continues to inspire us and which has emerged out of decades of critical analysis of racial capitalism alongside grassroots solidarity and resistance (see Gilmore, 2022).
