The continued “maturation” of late-stage capitalism saw multiple societal trends intersect violently in the 2020s. The Covid-19 pandemic intersected with real-time climate collapse and ongoing state violence against Indigenous, black, and other racialized people, which triggered spontaneous mass mobilisations against these multiple oppressions. That spontaneous display of anger towards the status quo spilled over into the labour movement as well. With decades of neoliberal austerity and outsourcing, union representation in Canada has fallen to only 30%. At the same time, the pandemic killed off and disabled a record number of workers and forced even more into early retirement. Workers now wield more economic leverage while being less organised than earlier periods of labour struggle. This combination of material factors built up to “The Great Resignation,” where individual workers eschew any company loyalty to take advantage of a labour shortage to maximise individual gains. But bubbling under the surface of this hyper-individualised approach to bargaining with the bosses is a resurgence in strike action of multiple flavours. Unions in multiple sectors struck for safer work conditions, better pay, an end to two-tiered contracts, and more. Yet many non-unionised workers, particularly front-line workers, also stood up and collectively struck in illegal job actions known as wildcat strikes. Given historic levels of worker upheaval and societal crisis combined with low levels of union representation, it is imperative to understand the wildcat strike as a tactic. By looking at important wildcat strikes in North American history, from the Pullman strike of 1894 to the 2020 wildcat of Albertan healthcare workers, we will highlight important lessons for the labour movement going forward
