The reasons:
(i) When there is plenty of labour, wages are low. So industrialists had no problem of labour shortage or high wage costs. They did not want to introduce machines that got rid of human labour and required large capital investment.
(ii) In many industries the demand for labour was seasonal. Gas works and breweries were especially busy through the cold months. So they needed more workers to meet their peak demand. Bookbinders and printers, catering to Christmas demand, too needed extra hands before December.
(iii) At the waterfront, winter was the time that ships were repaired and spruced up. In all such industries where production fluctuated with the season, industrialists usually preferred hand labour, employing workers for the season.
(iv) A range of products could be produced only with hand labour. Machines were oriented to producing uniforms, standardised goods for a mass market. But the demand in the market was often for goods with intricate designs and specific shapes.These required human skill, not mechanical technology.
