Women workers in Britain attacked the Spinning Jenny because it speeded up the spinning process, and consequently, reduced labour demand. By the use of this machine, a single worker could turn a number of spindles, and spin several threads at a time. This caused a valid fear of unemployment among women working in the woolen industry. Thus, uncertainty of jobs made workers hostile to the introduction of new technology. Till date, they had survived on hand spinning, but this was replaced in peril by the new machine. So when the Spinning Jenny was introduced in the woolen industry women started attacking the new machines and this conflict over the introduction of the Jenny continued for a long time.
