Labor rights or workers' rights are both legal rights and human rights relating to labor relations between workers and employers. These rights are codified in national and international labor and employment law. In general, these rights influence working conditions in relations of employment. One of the most prominent is the right to freedom of association, otherwise known as the right to organize. Workers organized in trade unions exercise the right to collective bargaining to improve working conditions. Labor background Throughout history, workers claiming some sort of right have attempted to pursue their interests. During the Middle Ages, the Peasants' Revolt in England expressed demand for better wages and working conditions. One of the leaders of the revolt, John Ball famously argued that people were born equal saying, "When Adam delved and Eve span, who was then the gentleman?" Laborers often appealed to traditional rights. For instance, English peasants fought against the enclosure movement, which took traditionally communal lands and made them private. The British Parliament passed the Factory Act 1833 which stated that children under the age of 9 could not work, children aged 9–13 could only work 8 hours a day, and children aged 14–18 could only work for 12 hours a day. Labor rights are a relatively new addition to the modern corpus of human rights. The modern concept of labor rights dates to the 19th century after the creation of labor unions following the industrialization processes. Karl Marx stands out as one of the earliest and most prominent advocates for workers rights. His philosophy and economic theory focused on labor issues and advocates his economic system of socialism, a society which would be ruled by the workers. Many of the social movements for the rights of the workers were associated with groups influenced by Marx such as the socialists and communists. More moderate democratic socialists and social democrats supported worker's interests as well. More recent workers rights advocacy has focused on the particular role, exploitation, and needs of women workers, and of increasingly mobile global flows of casual, service, or guest workers. Core labor standards Identified by the ILO in the Declaration on Fundamental Principles and Rights at Work, core labor standards are "widely recognized to be of particular importance". They are universally applicable, regardless of whether the relevant conventions have been ratified, the level of development of a country or cultural values. These standards are composed
