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 Wage slavery is a term used to criticize exploitation of labour by business, by keeping wages low or stagnant in order to maximize profits. The situation of wage slavery can be loosely defined as a person's dependence on wages (or a salary) f ...
", 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

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.

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.

Labour law

Union law varies from country to country, as does the function of unions. For example, German and Dutch unions have played a greater role in management decisions through participation in supervisory boards and co-determination than other countries. Moreover, in the United States, collective bargaining is most commonly undertaken by unions directly with employers, whereas in Austria, Denmark, Germany or Sweden, unions most often negotiate with 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

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

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.
