This article takes as its subject the handspinners of Yorkshire's eighteenth-century worsted industry. When not ignored altogether, historians have presented handspinners as invariably weak and passive. While manufacturers exploited the industry's women workers, spinners were neither submissive nor compliant. Their history, in part, was one of resistance. Spinners' everyday resistance took its most important form in the unauthorized practice of supplementing money wages with yarn and wool from the production process. The scale and extent of such pilfering led manufacturers to one of the more remarkable initiatives in eighteenth-century industrial relations: the establishment of an industrial police force to detect and prosecute embezzlement. Policing would play a major role in the industry. Ultimately, however, its limitations helped to prompt manufacturers to pursue organizational and technological innovations to bring greater order to the spinning sector. Thus spinners' prosaic resistance had the unforeseen consequence of contributing to the demise of their occupation.
