The concept's analytical power comes from its inversion of the standard framing. Conventional history treated crowd violence as a breakdown requiring suppression. Thompson treated it as a political practice requiring interpretation — and the interpretation revealed discipline, targeting, and principled motivation where earlier analysts had seen only chaos.
The structural function is the same across centuries: the improvised assertion of interests that formal governance mechanisms refuse to acknowledge. The eighteenth-century food rioter enforcing a just price, the Nottinghamshire framework knitter breaking the offending frame, the 2023 visual artist filing a class-action lawsuit against an AI company that scraped her portfolio — each is performing collective bargaining by riot, improvising a mechanism of voice from whatever materials are available when institutional mechanisms are absent.
Thompson was unsentimental about the limits of the practice. The food riot enforced a just price for a day. The framework knitters compelled attention for a season. Neither created durable institutional structures. The durable structures — trade unions, factory acts, franchise extensions — came later, built through decades of organizing, and came because the extra-institutional actions demonstrated, at significant human cost, that the institutional deficit was intolerable.
The contemporary collective bargaining by code — the lawsuits, strikes, and petitions of AI-affected workers — faces the same structural limitation. Each action signals the need for structures. None is the structure itself. The question is whether the signals will be heeded in time to produce institutional innovation, or whether they will be dismissed as Luddism until the accumulated injustice makes institutional response unavoidable.
Thompson developed the phrase in the 1960s essays that preceded his 1971 moral economy essay, drawing on earlier usage by historians including Eric Hobsbawm, who had used similar formulations to describe machine-breaking as a form of wage negotiation by pre-industrial workers.
Structural function over formal classification. The political function of the action matters more than its legal classification — lawful petition and unlawful riot can serve the same structural purpose.
Institutional deficit as precondition. Direct action emerges when formal channels are closed or captured, not when they are functioning.
Signal without structure. The riot, like the modern lawsuit, compels momentary attention but does not create the durable representation that sustains interests over time.
Demonstrative necessity. Extra-institutional action makes the institutional deficit visible, creating political pressure for institutional innovation.
