described trade unions thus: "The value of labour-power constitutes the conscious and explicit foundation of the trade unions, whose importance for the ... working class can scarcely be overestimated. The trade unions aim at nothing less than to prevent the reduction of wages below the level that is traditionally maintained in the various branches of industry. That is to say, they wish to prevent the price of labour-power from falling below its value" (''Capital'' V1, 1867, p. 1069). Early
socialists also saw trade unions as a way to
democratize the workplace, in order to obtain political power.

in 1574, but the vast majority of people remained as
tenant-farmers on estates owned by the
landed aristocracy. This transition was not merely one of relocation from rural to urban environs; rather, the nature of industrial work created a new class of "worker". A farmer worked the land, raised animals and grew crops, and either owned the land or paid rent, but ultimately sold a ''product'' and had control over his life and work. As industrial workers, however, the workers sold their work as labour and took directions from employers, giving up part of their freedom and self-agency in the service of a master. The critics of the new arrangement would call this "
wage slavery", but the term that persisted was a new form of human relations: employment. Unlike farmers, workers often had less control over their jobs; without job security or a promise of an on-going relationship with their employers, they lacked some control over the work they performed or how it impacted their health and life. It is in this context that modern trade unions emerge.
In the cities, trade unions encountered much hostility from employers and government groups. In the United States, unions and unionists were regularly prosecuted under various restraint of trade and conspiracy laws, such as the
Sherman Antitrust Act.
This pool of unskilled and semi-skilled labour spontaneously organized in fits and starts throughout its beginnings, and would later be an important arena for the development of trade unions. Trade unions have sometimes been seen as successors to the

Combination Act 1825 restricted their activity to bargaining for wage increases and changes in working hours.
By the 1810s, the first labour organizations to bring together workers of divergent occupations were formed. Possibly the first such union was the General Union of Trades, also known as the Philanthropic Society, founded in 1818 in

National general unions

The first attempts at forming a national
general union in the United Kingdom were made in the 1820s and 30s. The
National Association for the Protection of Labour was established in 1830 by
John Doherty, after an apparently unsuccessful attempt to create a similar national presence with the National Union of Cotton-spinners. The Association quickly enrolled approximately 150 unions, consisting mostly of
textile related unions, but also including mechanics, blacksmiths, and various others. Membership rose to between 10,000 and 20,000 individuals spread across the five counties of

In 1834, the Welsh socialist
Robert Owen established the
Grand National Consolidated Trades Union. The organization attracted a range of
socialists from Owenites to revolutionaries and played a part in the protests after the
Tolpuddle Martyrs' case, but soon collapsed.
More permanent trade unions were established from the 1850s, better resourced but often less radical. The
London Trades Council was founded in 1860, and the

John Stuart Mill (20 May 1806 – 7 May 1873) was an English philosopher, political economist, politician and civil servant. One of the most influential thinkers in the history of liberalism and social liberalism, he contributed widely to s ...
wrote:
If it were possible for the working classes, by combining among themselves, to raise or keep up the general rate of wages, it needs hardly be said that this would be a thing not to be punished, but to be welcomed and rejoiced at. Unfortunately the effect is quite beyond attainment by such means. The multitudes who compose the working class are too numerous and too widely scattered to combine at all, much more to combine effectually. If they could do so, they might doubtless succeed in diminishing the hours of labour, and obtaining the same wages for less work. They would also have a limited power of obtaining, by combination, an increase of general wages at the expense of profits.
Beyond this claim, Mill also argued that, because individual workers had no basis for assessing the wages for a particular task, labour unions would lead to greater efficiency of the market system.
Legalization, expansion and recognition
British trade unions were finally legalized in 1872, after a ''
Royal Commission on Trade Unions'' in 1867 agreed that the establishment of the organizations was to the advantage of both employers and employees.
This period also saw the growth of trade unions in other industrializing countries, especially the United States, Germany and France.
In the United States, the first effective nationwide labour organization was the
Knights of Labor, in 1869, which began to grow after 1880. Legalization occurred slowly as a result of a series of court decisions. The
Federation of Organized Trades and Labor Unions began in 1881 as a federation of different unions that did not directly enrol workers. In 1886, it became known as the
American Federation of Labor or AFL.

The decline in manufacturing is the most direct influence, as unions were historically beneficial and prevalent in the sector; for this reason, there may be an increase in
developing nations as OECD nations continue to export manufacturing industries to these markets. The second reason is globalization, which makes it harder for unions to maintain standards across countries. The last reason is governmental policies. These come from both sides of the political spectrum. In the UK and US, it has been mostly right-wing proposals that make it harder for unions to form or that limit their power. On the other side, there are many social policies such as

Informal workers often face unique challenges when trying to participate in trade union movements as formal trade union organizations recognized by the state and employers may not accommodate for the employment categories common in the informal economy. Simultaneously, the lack of regular work locations and loopholes relating to
false self-employment add barriers and costs for the trade unions when trying to organize the informal economy. This has been a significant threshold to labour organizing in
low-income countries, where the labour force mostly works in the informal economy.

employers associations, a form of
sectoral bargaining.
Concerning labour market regulation in the EU, Gold (1993) and Hall (1994) have identified three distinct systems of labour market regulation, which also influence the role that unions play:
* "In the Continental European System of labour market regulation, the government plays an important role as there is a strong legislative core of employee rights, which provides the basis for agreements as well as a framework for discord between unions on one side and employers or employers' associations on the other. This model was said to be found in EU core countries such as Belgium, France, Germany, the Netherlands and Italy, and it is also mirrored and emulated to some extent in the institutions of the EU, due to the relative weight that these countries had in the EU until the EU expansion by the inclusion of 10 new

an member states in 2004.
* In the Anglo-Saxon System of labour market regulation, the government's legislative role is much more limited, which allows for more issues to be decided between employers and employees and any union or employers' associations which might represent these parties in the decision-making process. However, in these countries, collective agreements are not widespread; only a few businesses and a few sectors of the economy have a strong tradition of finding collective solutions in labour relations.

and the UK belong to this category, and in contrast to the EU core countries above, these countries first joined the EU in 1973.
* In the Nordic System of labour market regulation, the government's legislative role is limited in the same way as in the Anglo-Saxon system. However, in contrast to the countries in the Anglo-Saxon system category, this is a much more widespread network of collective agreements, which covers most industries and most firms. This model was said to encompass Denmark, Finland, Norway and Sweden. Here, Denmark joined the EU in 1973, whereas Finland and Sweden joined in 1995."
The United States takes a more

approach, setting some minimum standards but leaving most workers' wages and benefits to collective bargaining and market forces. Thus, it comes closest to the above Anglo-Saxon model. Also, the Eastern European countries that have recently entered into the EU come closest to the Anglo-Saxon model.
In contrast, in Germany, the relation between individual employees and employers is considered to be asymmetrical. In consequence, many working conditions are not negotiable due to a strong legal protection of individuals. However, the German flavor or works legislation has as its main objective to create a balance of power between employees organized in unions and employers organized in employers' associations. This allows much wider legal boundaries for collective bargaining, compared to the narrow boundaries for individual negotiations. As a condition to obtain the legal status of a trade union, employee associations need to prove that their leverage is strong enough to serve as a counterforce in negotiations with employers. If such an employee's association is competing against another union, its leverage may be questioned by unions and then evaluated in labour court. In Germany, only very few professional associations obtained the right to negotiate salaries and working conditions for their members, notably the medical doctor's association and the pilots association . The engineer's association
Verein Deutscher Ingenieure does not strive to act as a union, as it also represents the interests of engineering businesses.
Beyond the classification listed above, unions' relations with political parties vary. In many countries unions are tightly bonded, or even share leadership, with a political party intended to represent the interests of the working class. Typically, this is a

Shop types
Companies that employ workers with a union generally operate on one of several models:
* A
closed shop (US) or a "pre-entry closed shop" (UK) employs only people who are already union members. The compulsory
hiring hall is an example of a closed shop—in this case the employer must recruit directly from the union, as well as the employee working strictly for unionized employers.
* A
union shop
In labor law, a union shop, also known as a post-entry closed shop, is a form of a union security clause. Under this, the employer agrees to either only hire labor union members or to require that any new employees who are not already union mem ...

requires non-union workers to pay a fee to the union for its services in negotiating their contract. This is sometimes called the
Rand formula.
* An
open shop does not require union membership in employing or keeping workers. Where a union is active, workers who do not contribute to a union may include those who approve of the union contract (
free riders) and those who do not. In the United States, state level
right-to-work laws mandate the open shop in some states. In Germany only open shops are legal; that is, all discrimination based on union membership is forbidden. This affects the function and services of the union.
An EU case concerning Italy stated that, "The principle of trade union freedom in the Italian system implies recognition of the right of the individual not to belong to any trade union ("negative" freedom of association/trade union freedom), and the unlawfulness of discrimination liable to cause harm to non-unionized employees."
In the United Kingdom, previous to this EU jurisprudence, a series of laws introduced during the 1980s by Margaret Thatcher's government restricted closed and union shops. All agreements requiring a worker to join a union are now illegal. In the United States, the
Taft–Hartley Act of 1947 outlawed the closed shop.

Impact
Economics

The academic literature shows substantial evidence that trade unions reduce
economic inequality.
The economist
Joseph Stiglitz has asserted that, "Strong unions have helped to reduce inequality, whereas weaker unions have made it easier for
CEOs, sometimes working with market forces that they have helped shape, to increase it." Evidence indicates that those who are ''not'' members of unions also see higher wages. Researchers suggest that unions set industrial norms as firms try to stop further unionization or losing workers to better-paying competitors.
The decline in unionization since the 1960s in the United States has been associated with a pronounced rise in

income.
Right-to-work laws have been linked to greater economic inequality in the United States.
Research from Norway has found that high unionization rates lead to substantial increases in firm productivity, as well as increases in workers' wages. Research from Belgium also found productivity gains, although smaller. However, other research in the United States has found that unions can harm profitability, employment and business growth rates. UK research on employment, wages, productivity, and investment found union density improved all metrics - but only until a limit. Forming U-shaped curves, after an optimal density, more unionisation ''worsened'' employment, wages, etc. Research from the

sought to show that unionization produces higher wages (for the union members) at the expense of fewer jobs, and that, if some industries are unionized while others are not, wages will tend to decline in non-unionized industries.
Friedrich Hayek criticized unions in chapter 18 of his publication ''
The Constitution of Liberty''.
Trade unions frequently advocate for
seniority-based compensation and against
meritocracy.
Politics
In the United States, the weakening of unions has been linked to more favourable electoral outcomes for the Republican Party. Legislators in areas with high unionization rates are more responsive to the interests of the poor, whereas areas with lower unionization rates are more responsive to the interests of the rich. Higher unionization rates increase the likelihood of parental leave policies being adopted. Republican-controlled states are less likely to adopt more restrictive labour policies when unions are strong in the state.
Research in the United States found that American congressional representatives were more responsive to the interests of the poor in districts with higher unionization rates. Another 2020 American study found an association between US state level adoption of parental leave legislation and trade union strength.
In the United States, unions have been linked to lower racial resentment among whites. Membership in unions increases political knowledge, in particular among those with less formal education.
Public-sector trade unions have been associated with increased cost of government.
Health
In the United States, higher union density has been associated with lower suicide/overdose deaths.
Decreased unionization rates in the United States have been linked to an increase in occupational fatalities.
