The general strike is, in the first instance, a tactic: the simultaneous cessation of work by the vast majority of a nation's or city's workforce, cutting across industries, sectors, and occupational categories, in pursuit of political or economic objectives. But it is also something more than a tactic. It is a concept — a theoretical object through which generations of labor thinkers, revolutionary strategists, and social philosophers have imagined what a society organized around labor rather than capital might look like, feel like, and become. The general strike as concept exceeds any particular historical instance of it. It is, as Georges Sorel argued in his 1908 Reflections on Violence, a myth in the most serious sense: a mobilizing image of total transformation that gives daily struggles their significance by relating them to a horizon of ultimate possibility.

Understanding the general strike as a concept requires distinguishing between two versions that have coexisted, competed, and sometimes merged in labor thought. The first is the general strike as ultimate weapon: a finite, strategic deployment of collective withdrawal designed to extract maximum concessions from employers or governments within the existing order. This version dominated mainstream trade union thinking in the early twentieth century and informed the British General Strike of 1926. It treats the general strike as an intensification of ordinary strike logic — bigger, more disruptive, more coercive, but ultimately bargaining within the system. The second version is the general strike as social revolution: not a weapon for reform but an act of system replacement, in which workers' collective withdrawal from capitalist production simultaneously dismantles capitalist authority and instantiates workers' self-organization as the new social order. This version, associated with anarcho-syndicalists, revolutionary industrial unionists (the IWW), and council communists, treats the general strike not as a moment of maximum pressure but as the constitutive moment of a new society.

The conceptual power of the general strike lies in what it reveals about the structure of capitalist society: that all of it — factories and offices, transportation and communication, hospitals and schools — depends on labor, and that labor's withdrawal is therefore an act of world-making as much as world-stopping. This insight, which sounds obvious when stated, is politically revolutionary in its implications. If workers produce everything, then they can, in principle, choose what gets produced, how, and for whom. The general strike is the moment at which that latent sovereignty becomes actual.

Sorel's treatment remains philosophically the most searching. For Sorel, the general strike is not primarily valuable as a strategy that might succeed; it is valuable as a myth that sustains revolutionary energy and moral seriousness in the labor movement. The belief in the possibility of the general strike keeps workers from the degradation of purely defensive, reactive unionism. It provides a telos — a purpose — that transforms the daily grind of grievance-handling and collective bargaining into episodes in a larger narrative of emancipation. Whether the general strike is literally achievable matters less, in Sorel's framework, than whether the image of it is vivid enough to generate the creative violence — the energy, the moral intensity, the willingness to break with routine — that genuine social transformation requires.

This conceptual function — the general strike as horizon rather than plan — has real organizational consequences. Movements that hold the general strike as a serious possibility tend to build differently from those that do not: more attention to cross-sector solidarity, more emphasis on the political as well as the economic dimensions of labor struggle, more investment in the cultural and educational infrastructure that makes sustained mass action possible. The IWW's "One Big Union" vision, the syndicalist federations of France and Spain, and the council communist movements of Germany and Hungary all organized with the general strike as their conceptual pole star, even when circumstances made its immediate realization impossible.

The general strike's conceptual status also shapes how it is suppressed. Ruling classes do not respond to general strikes merely as economic disruptions; they respond to them as challenges to political sovereignty. The deployment of military force against the 1894 Pullman Strike, the 1919 Winnipeg General Strike, and the 1934 San Francisco General Strike reflected not only economic interest but the perception that a successful general strike would delegitimize the state's monopoly on social organization. The general strike's threat is not simply to profit but to the entire architecture of authority that makes capitalist production possible.

In contemporary labor thought, the general strike concept has been reinvigorated by the climate crisis. Environmental activists and labor organizers have converged on the idea of a climate general strike — a global work stoppage in defense of ecological conditions of human life — as a form that matches the scale of the crisis. The concept's ancient resonances with revolutionary transformation are here pressed into the service of survival rather than purely redistributive justice, marking a new phase in the concept's long history.
