Minimum wage law is the body of law which prohibits employers from hiring employees or workers for less than a given hourly, daily or monthly minimum wage. More than 90% of all countries have some kind of minimum wage legislation.

Until recently, minimum wage laws were usually very tightly focused. In the US and Great Britain, for example, they applied only to women and children. Only after the Great Depression did many industrialized economies extend them to the general work force. Even then, the laws were often specific to certain industries. In France, for example, they were extensions of existing trade union legislation. In the US, industry specific wage restrictions were held to be unconstitutional. The country's Fair Labor Standards Act of 1938 established a uniform national minimum wage for nonfarm, nonsupervisory workers. Coverage was later extended to most of the labor force.

In Mesopotamia during the reign of Hammurabi, minimum wage rates were set by law.A History of Advertising The First 300,000 Years By Jef I Richards, 2022, P.18 In 1894, New Zealand established arbitration boards with the Industrial Conciliation and Arbitration Act. In 1896, the colony of Victoria, Australia established similar boards. In 1907, the Harvester decision was handed down in Australia. It established a 'living wage' for a man, his wife and two children to "live in frugal comfort." In 1909, the Trade Boards Act was enacted in the United Kingdom, establishing four such boards. In 1912, the state of Massachusetts, United States, set minimum wages for women and children. In the United States, statutory minimum wages were first introduced nationally in 1938. In the 1960s, minimum wage laws were introduced into Latin America as part of the Alliance for Progress; however these minimum wages were, and are, low. p. 342.

Several conventions of the International Labour Organization provide for "minimum wage fixing" for rights of labours, for example: Minimum Wage-Fixing Machinery Convention, 1928, Minimum Wage Fixing Machinery (Agriculture) Convention, 1951, and Minimum Wage Fixing Convention, 1970.

Minimum wage law by jurisdiction

Australia The Australian National Minimum Wage is the minimum base rate of pay for ordinary hours worked to any employee who is not covered by a Modern Award or an Agreement.Australian Fair Work Ombudsman, Minimum Wages Fact Sheet (accessed 27 July 2012) In 1896 in Victoria, Australia, an amendment to the Factories Act provided for the creation of a wages board. The wages board did not set a universal minimum wage; rather it set basic wages for 6 industries that were considered to pay low wages.Waltman, Jerold. "The Politics of the Minimum Wage." University of Illinois Press. 2000 First enacted as a four-year experiment, the wages board was renewed in 1900 and made permanent in 1904; by that time it covered 150 different industries. By 1902, other Australian states, such as New South Wales and Western Australia, had also formed wages boards. The notion of a "basic wage" was established in 1907 with the Harvester Judgment. In Australia, on 14 December 2005, the Australian Fair Pay Commission was established under the Workplace Relations Amendment (WorkChoices) Act 2005 responsible for the adjustment of the standard federal minimum wage, replacing the role of the Australian Industrial Relations Commission that took submissions from a variety of sources to determine appropriate minimum wages. The Australian Fair Pay Commission was replaced by Fair Work Australia in 2010.

Canada

Under the Canadian Constitution's federal-provincial division of powers, the responsibility for enacting and enforcing labour laws rests with the ten provinces; the three territories also were granted this power by virtue of federal legislation. This means that each province and territory has its own minimum wage. Some provinces allow lower wages to be paid to liquor servers and other tip earners, and/or to inexperienced employees.

The federal government could theoretically set its own minimum wage rates for workers in federal jurisdiction industries (interprovincial railways, for example). As of 2006 however, the federal minimum wage is defined to be the general adult minimum wage rate of the province or territory where the work is performed. This means, for example, that an interprovincial railway company could not legally pay a worker in British Columbia less than $10.45 an hour regardless of the worker's experience.

People's Republic of China

The Ministry of Human Resources and Social Security set the People's Republic of China's first minimum wage law on 1 March 2004. The Regulations on Enterprises Minimum Wage was made to "ensure the basic needs of the worker and his family, to help improve workers' performance and to promote fair competition between enterprises." One monthly minimum wage was set for full-time workers, and one hourly minimum wage for part-time workers. Provinces, municipalities, and autonomous regions are allowed to legislate for their own minimum wage separate from the national one.

Alongside local discretion in minimum wage standards, national rules also provide for how those standards are defined and enforced. China’s Minimum Wage Rules (2004) set minimum wage standards that cover employers and workers nationwide, with rules on how these standards are structured and updated locally. The Rules distinguish between monthly minimum wages for full-time workers and hourly minimum wages for part-time workers, direct provincial labor regulators to develop local minimum wage plans through an approval process, and require that standards be adjusted as necessary and revised at least once every two years. Under the Rules, county labor regulators and local labor unions are tasked with overseeing employer compliance with local standards and are empowered to request enforcement against and order noncompliant employers to correct violations, pay any owed wages, and, in some cases, pay compensatory damages of one to five times owed wages.
