Manual labour in the context of "Working class"

Tillage is the agricultural preparation of soil by mechanical agitation of various types, such as digging, stirring, and overturning. Examples of human-powered tilling methods using hand tools include shoveling, picking, mattock work, hoeing, and raking. Examples of draft-animal-powered or mechanized work include ploughing (overturning with moldboards or chiseling with chisel shanks), rototilling, rolling with cultipackers or other rollers, harrowing, and cultivating with cultivator shanks (teeth).

Tillage that is deeper and more thorough is classified as primary, and tillage that is shallower and sometimes more selective of location is secondary. Primary tillage such as ploughing tends to produce a rough surface finish, whereas secondary tillage tends to produce a smoother surface finish, such as that required to make a good seedbed for many crops. Harrowing and rototilling often combine primary and secondary tillage into one operation.

Harvesting is the process of collecting plants, animals, or fish (as well as fungi) as food, especially the process of gathering mature crops, and "the harvest" also refers to the collected crops. Reaping is the cutting of grain or pulses for harvest, typically using a scythe, sickle, or reaper. On smaller farms with minimal mechanization, harvesting is the most labor-intensive activity of the growing season. On large mechanized farms, harvesting uses farm machinery, such as the combine harvester. Automation has increased the efficiency of both the seeding and harvesting processes. Specialized harvesting equipment, using conveyor belts for gentle gripping and mass transport, replaces the manual task of removing each seedling by hand. The term "harvesting" in general usage may include immediate postharvest handling, including cleaning, sorting, packing, and cooling.

The completion of harvesting marks the end of the growing season, or the growing cycle for a particular crop, and the social importance of this event makes it the focus of seasonal celebrations such as harvest festivals, found in many cultures and religions.

Penal labour or prison labour is a term for various kinds of forced labour that prisoners are required to perform, typically manual labour. The work may be light or hard, depending on the context. Forms of sentence involving penal labour have included involuntary servitude, penal servitude, and imprisonment with hard labour. The term may refer to several related scenarios: labour as a form of punishment, the prison system used as a means to secure labour, and labour as providing occupation for convicts. These scenarios are sometimes applied to those imprisoned for political, religious, war, or other reasons as well as to criminal convicts.

Large-scale implementations of penal labour include labour camps, prison farms, penal colonies, penal military units, penal transportation, or aboard prison ships.

Extensive farming or extensive agriculture (as opposed to intensive farming) is an agricultural production system that uses small inputs of labor, fertilizers, and capital, relative to the land area being farmed.

Mechanised agriculture or agricultural mechanisation is the use of machinery and equipment, ranging from simple and basic hand tools to more sophisticated, motorised equipment and machinery, to perform agricultural operations. In modern times, powered machinery has replaced many farm task formerly carried out by manual labour or by working animals such as oxen, horses and mules.

The entire history of agriculture contains many examples of the use of tools, such as the hoe and the plough. The ongoing integration of machines since the Industrial Revolution has allowed farming to become much less labour-intensive.

A sawmill (saw mill, saw-mill) or lumber mill is a facility where logs are cut into lumber. Modern sawmills use a motorized saw to cut logs lengthwise to make long pieces, and crosswise to length depending on standard or custom sizes (dimensional lumber). The "portable" sawmill is simple to operate. The log lies flat on a steel bed, and the motorized saw cuts the log horizontally along the length of the bed, by the operator manually pushing the saw. The most basic kind of sawmill consists of a chainsaw and a customized jig ("Alaskan sawmill"), with similar horizontal operation.

Before the invention of the sawmill, boards were made in various manual ways, either rived (split) and planed, hewn, or more often hand sawn by two men with a whipsaw, one above and another in a saw pit below. The earliest known mechanical mill is the Hierapolis sawmill, a Roman water-powered stone mill at Hierapolis, Asia Minor dating back to the 3rd century AD. Other water-powered mills followed and by the 11th century they were widespread in Spain and North Africa, the Middle East and Central Asia, and in the next few centuries, spread across Europe. The circular motion of the wheel was converted to a reciprocating motion at the saw blade. Generally, only the saw was powered, and the logs had to be loaded and moved by hand. An early improvement was the development of a movable carriage, also water powered, to move the log steadily through the saw blade.

A blue-collar worker is a person who performs manual labor or skilled trades. Blue-collar work may involve skilled or unskilled labor. The type of work may involve manufacturing, warehousing, mining, carpentry, electrical work, custodial work, agriculture, logging, landscaping, food processing, waste collection and disposal, construction, shipping, and many other types of physical work. Blue-collar work often involves something being physically built or maintained. In social status, blue-collar workers generally belong to the working class.

In contrast, the white-collar worker typically performs work in an office environment and may involve sitting at a computer or desk. A third type of work is a service worker (pink collar) whose labor is related to customer interaction, entertainment, sales or other service-oriented work — particularly those service jobs that have been traditionally considered to be women's work, such as secretaries, nurses, teachers, early childhood educators, florists, etc. Many occupations blend blue, white, or pink-collar work and are often paid hourly wage-labor, although some professionals may be paid by the project or salaried. There are a wide range of payscales for such work depending upon field of specialty and experience.
