Manual labour



Manual labour (in Commonwealth English, manual labor in American English) or manual work is physical work done by humans, in contrast to labour by machines and working animals. It is most literally work done with the hands (the word manual coming from the Latin word for hand) and, by figurative extension, it is work done with any of the muscles and bones of the human body. For most of human prehistory and history, manual labour and its close cousin, animal labour, have been the primary ways that physical work has been accomplished. Mechanisation and automation, which reduce the need for human and animal labour in production, have existed for centuries, but it was only starting in the 18th and 19th centuries that they began to significantly expand and to change human culture. To be implemented, they require that sufficient technology exist and that its capital costs be justified by the amount of future wages that they will obviate. Semi-automation is an alternative to worker displacement that combines human labour, automation, and computerisation to leverage the advantages of both man and machine.

Although nearly any work can potentially have skill and intelligence applied to it, many jobs that mostly comprise manual labour—such as fruit and vegetable picking, manual materials handling (for example, shelf stocking), manual digging, or manual assembly of parts—often may be done successfully (if not masterfully) by unskilled or semiskilled workers. For these reasons, there is a partial but significant correlation between manual labour and unskilled or semiskilled workers. Based on economic and social conflict of interest, people may often distort that partial correlation into an exaggeration that equates manual labour with lack of skill; with lack of any potential to apply skill (to a task) or to develop skill (in a worker); and with low social class. Throughout human existence the latter has involved a spectrum of variants, from slavery (with stigmatisation of the slaves as 'subhuman'), to caste or caste-like systems, to subtler forms of inequality.

There are diverse viewpoints regarding the definition of manual labor, and the progression from manual labor to more complex forms can be ambiguous. Authors such as Marx characterize it as simple labor, controversially proposing that all labor can be categorized as such. However, Ludwig von Mises argues that this is an oversimplification, highlighting it as a reason many socialist economic policies face challenges, particularly concerning the economic calculation problem. On the other hand, Paul Cockshott and Allin Cottrell advocate for considering all labor as simple labor, emphasizing the importance of accounting for training in more complex forms of labor. This complexity extends to determining what constitutes unskilled labor, as it raises questions about the nature of labor performed by students when training for specific professions. Ultimately, definitions of manual labor are shaped by economic and political interests, as all societies depend on some form of manual labor for their functioning.

Economic competition often results in businesses trying to buy labour at the lowest possible cost (for example, through offshoring or by employing foreign workers) or to obviate it entirely (through mechanisation and automation).

Relationship between low skill and low social class
There is a strong correlation between manual labour and unskilled or semiskilled workers, despite the fact that nearly any work can potentially have skill and intelligence applied to it (for example, the artisanal skill of craft production, or the logic of applied science). It has always been the case for humans that many workers begin their working lives lacking any special level of skill or experience. (In the past two centuries, education has become more important and more widely disseminated; but even today, not everyone can know everything, or have experience in a great number of occupations.) It has also always been the case that there was a large amount of manual labour to be done; and that much of it was simple enough to be successfully (if not masterfully) done by unskilled or semiskilled workers, which has meant that there have always been plenty of people with the potential to do it. These conditions have assured the correlation's strength and persistence.

Throughout human prehistory and history, wherever social class systems have developed, the social status of manual labourers has, more often than not, been low, as most physical tasks were done by peasants, serfs, slaves, indentured servants, wage slaves, or domestic servants. For example, legal scholar L. Ali Khan analyses how the Greeks, Hindus, English, and Americans all created sophisticated social structures to outsource manual labour to distinct classes, castes, ethnicities, or races.
