Work can take many different forms, as various as the environments, tools, skills, goals, and institutions around a worker.

Societies also commonly rank different work roles by perceived status, but this is more subjective and goes beyond clear progressions within a single industry.

At the same time, a wide swathe of roles across all industries may be afforded more status (e.g.

insights led to the creation and widespread adoption of fast, general-purpose computers. Just as mechanization can substitute for the physical labor of many human beings, computers allow for the partial automation of mental work previously carried out by human workers, such as computer (job description), calculations, transcription (service), document transcription, and basic customer service requests. Research and development of related technologies like machine learning and robotics continues into the 21st century. Beyond tools and machines used to actively perform tasks, workers benefit when other passive elements of their work and environment are designed properly. This includes everything from personal items like workwear and safety gear to features of the workspace itself like furniture, lighting, HVAC, air quality, and even the underlying architecture.


In society


Organizations

Even if workers are personally ready to perform their jobs, coordination is required for any effort outside of individual subsistence to succeed. At the level of a small team working on a single task, only cooperation and good communication may be necessary. As the complexity of a work process increases though, requiring more planning or more workers focused on specific tasks, a reliable organization becomes more critical. Economic organizations often reflect social thought common to their time and place, such as ideas about human nature or hierarchy. These unique organizations can also be historically significant, even forming major pillars of an economic system. In European history, for instance, the decline of guilds and rise of joint-stock companies goes hand-in-hand with other changes, like the growth of centralized state (polity), states and capitalism. In industrialized economies, labor unions are another significant organization. In isolation, a worker that is easily replaceable in the labor market has little power to demand better wages or conditions. By banding together and interacting with business owners as a corporate entity, the same workers can claim a larger share of the value created by their labor. While a union does require workers to sacrifice some autonomy in relation to their coworkers, it can grant workers more control over the work process itself in addition to material benefits.


Institutions

The need for planning and coordination extends beyond individual organizations to society as a whole too. Every successful work project requires effective resource allocation to provide necessities, materials, and fixed investment, investment (such as equipment and facilities). In smaller, traditional societies, these aspects can be mostly regulated through convention (norm), custom, though as societies grow, more extensive methods become necessary. These complex institutions, however, still have roots in common human activities. Even the free markets of modern capitalist societies rely fundamentally on
trade Trade involves the transfer of goods and services from one person or entity to another, often in exchange for money. Economists refer to a system or network that allows trade as a market. An early form of trade, barter, saw the direct excha ...
, while administrative-command system, command economies, such as in many communist states during the 20th century, rely on a highly bureaucracy, bureaucratic and hierarchical form of redistribution (cultural anthropology), redistribution. Other institutions can affect workers even more directly by delimiting practical day-to-day life or basic legal rights. For example, a caste system may restrict families to a narrow range of jobs, inherited from parent to child. In serfdom, a peasant has more rights than a slave but is attached to a specific piece of land and largely under the power of the landholder, even requiring permission to physically travel outside the land-holding. How institutions play out in individual workers' lives can be complex too; in most societies where wage-labor predominates, workers possess equal rights by law and mobility in theory. Without social support or other resources, however, the necessity of earning a livelihood may force a worker to cede some rights and freedoms in fact.


Values

Societies and subcultures may value work in general, or specific kinds of it, very differently. When social status or virtue is strongly associated with leisure and opposed to tedium, then work itself can become indicative of low social rank and devalued. In the opposite case, a society may hold strongly to a work ethic where work itself is seen as virtuous. For example, German sociologist Max Weber hypothesized that European capitalism originated in a Protestant work ethic, which emerged with the Reformation. For some, work may hold a spiritual value in addition to any secular notions. Especially in some monastic or mystical strands of several religions, simple manual labor may be held in high regard as a way to maintain the body, cultivate self-discipline and humility, and focus the mind.


Current issues

The contemporary world economy has brought many changes, overturning some previously widespread labor issues. At the same time, some longstanding issues remain relevant, and other new ones have emerged. One issue that continues despite many improvements is slave labor and human trafficking. Though ideas about universal rights and the economic benefits of free labor have significantly diminished the prevalence of outright slavery, it continues in lawless areas, or in attenuated forms on the margins of many economies. Another difficulty, which has emerged in most societies as a result of urbanization and industrialization, is unemployment. While the shift from a subsistence economy usually increases the overall productivity of society and lifts many out of poverty, it removes a baseline of material security from those who cannot find employment or other support. Governments have tried a range of strategies to mitigate the problem, such as improving the efficiency of job matching, conditionally providing welfare benefits or unemployment insurance, or even directly overriding the labor market through work-relief programs or a job guarantee. Since a job forms a major part of many workers' self-identity, unemployment can have severe psychological and social consequences beyond the financial insecurity it causes. One more issue, which may not directly interfere with the functioning of an economy but can have significant indirect effects, is when governments fail to account for work occurring out-of-view from the public sphere. This may be important, uncompensated work occurring everyday in private life; or it may be criminal activity that involves clear but furtive economic exchanges. By ignoring or failing to understand these activities, economic policies can have counter-intuitive effects and cause strains on the community and society.
