Q.What is meant by the ‘division of labour’, and how does the chapter describe the way modernisation and mechanisation have transformed the nature of work?

The division of labour refers to the specialisation of work tasks -- the way in which a production process, instead of being carried out from start to finish by a single worker, is broken up into a number of distinct occupations, each performed by different, specialised workers, which are then combined to produce the final good or service. Every society has at least some rudimentary division of labour -- even the simplest societies distinguish, for instance, between tasks typically performed by men and by women -- but the degree of specialisation increases enormously with industrialisation, to the point where, in the modern world, the division of labour operates on an international scale, with different countries specialising in different stages of global production.

Modernisation and mechanisation transformed the nature of work along several connected lines. In traditional, pre-industrial societies, non-agricultural work generally meant mastering an entire craft through a lengthy apprenticeship, after which a single worker carried out every stage of production -- from raw material to finished product -- largely on their own. Industrialisation broke this pattern apart. Work was now divided into an enormous number of separate, specialised occupations: a worker was trained for one narrow task within a much larger process and paid a wage specifically for that task, while a separate class of managers took on the job of supervising the workforce, aiming to raise productivity and enforce discipline rather than perform the production work themselves.

Mechanisation intensified this specialisation further. Industrial processes were broken down into simple, precisely timed operations suited to mass production for mass markets, culminating in innovations such as the moving assembly line, where each worker performed one small, repeated task as a product moved past them, rather than working on the product as a whole. This new scale of production also required expensive, centrally located machinery, which pulled work physically out of the home -- where it had previously been carried out collectively by household members -- and into factories, and it required continuous monitoring of employees to sustain the pace and quality the new machinery made possible.

More recently, globalisation has added a further layer to this transformation: many industries have shifted towards flexible production and the decentralisation of work, spreading different stages of a single production process across many firms and even countries, connected through long global supply chains -- as seen, for example, in the garment export industry, where a local manufacturer may directly control only a small fraction of the many operations that lie between an international designer and the final consumer. Modernisation and mechanisation, in other words, have not simply made work more efficient; they have progressively fragmented it into ever more specialised, geographically dispersed pieces, changing both how goods are produced and who holds power over the conditions of that production.
