International Workers' Day

International Workers' Day, also known as Workers' Day, Labour Day, or the labor-related observance of May Day, is an annual celebration of workers and the labor movement held on May 1 in many countries. The day has been associated with trade unions, the eight-hour workday movement, workplace rights, demonstrations, political movements, and efforts to improve working conditions.

International Workers' Day can be studied from many perspectives, including labor history, economics, sociology, political science, business, law, and the history of social movements. It provides a useful starting point for learning about how workers have organized collectively, how working conditions have changed, and how disagreements concerning wages, working hours, workplace power, and economic organization have developed.

The holiday has had different meanings in different countries and historical periods. It has been associated with trade unionism, socialism, communism, anarchism, social democracy, labor reform, and other political and economic traditions. For many people, however, the day functions more broadly as a celebration of workers and their contributions to society.

Origins and the eight-hour workday

International Workers' Day is closely connected with the nineteenth-century movement for the eight-hour workday.

During industrialization, many workers regularly worked substantially longer than eight hours per day. Labor organizations increasingly argued that workers should have more time outside of employment for family, recreation, education, civic participation, and rest.

A common slogan associated with the movement called for eight hours for work, eight hours for recreation, and eight hours for rest.

On May 1, 1886, workers across the United States participated in strikes and demonstrations demanding an eight-hour workday. Chicago was one of the major centers of the movement. The Library of Congress describes hundreds of thousands of workers participating in the broader campaign, with strikes and demonstrations taking place in multiple cities.

The events that followed in Chicago became particularly important to the history of May Day.

The Haymarket Affair

On May 3, 1886, police fired on workers during a labor conflict near the McCormick Reaper Works in Chicago, resulting in deaths and injuries. Labor activists organized a meeting at Haymarket Square for the following evening.

The May 4 meeting began peacefully. As police moved to disperse the gathering, someone threw a bomb toward the police. The explosion and subsequent gunfire killed police officers and civilians and injured many others.

Eight anarchists were prosecuted in connection with the bombing. The identity of the person who threw the bomb was never conclusively established. Four defendants were eventually executed, one died in prison before his scheduled execution, and three were later pardoned by Illinois Governor John Peter Altgeld.

The Haymarket Affair became an important event in international labor history. Supporters of the convicted men argued that the prosecution had been shaped substantially by their political beliefs and association with radical labor organizing. The events also intensified conflict concerning labor activism, anarchism, policing, immigration, and industrial relations.

The Library of Congress maintains collections of primary documents, newspapers, photographs, trial materials, and other resources that can be used to research the Haymarket Affair directly.

Development of International Workers' Day

The events in Chicago attracted attention beyond the United States.

In July 1889, delegates at the Second International, an international organization of socialist and labor parties, supported an international workers' demonstration to be held on May 1, 1890. The demonstrations were intended in part to support demands for limits on working hours.

May 1, 1890 saw workers' demonstrations in numerous European countries. The movement continued, and May Day developed into a recurring international workers' observance.

Over time, International Workers' Day spread to countries throughout Europe, Latin America, Asia, Africa, and other regions. In many countries May 1 eventually became an official public holiday.

The specific character of the observance has varied considerably. May Day events have included:

Labor union marches.
Demonstrations concerning wages and working conditions.
Political rallies.
Festivals and community gatherings.
Speeches and educational events.
Celebrations of workers and labor organizations.
Protests concerning unemployment or economic inequality.
Campaigns for workplace safety and labor rights.
Government-organized ceremonies and parades.

Different political movements have also attached their own meanings to May Day. Communist governments historically organized large state May Day celebrations, while democratic labor unions, socialist organizations, anarchists, social democrats, and other movements have organized their own forms of observance.

International Workers' Day and Labor Day in the United States

International Workers' Day should not be confused with the official United States holiday known as Labor Day.

The United States celebrates Labor Day on the first Monday in September. The first widely recognized Labor Day celebration took place in New York City on September 5, 1882. During the following years, several states established Labor Day holidays.

Congress made the first Monday in September a federal legal holiday in 1894.

The existence of two labor-related dates creates an interesting historical situation. The events that strongly influenced the development of International Workers' Day occurred in the United States, yet May 1 never became the principal official American labor holiday.

May Day has nevertheless continued to be observed by some American unions, political organizations, immigrant communities, worker organizations, and social movements.

Workers and society

International Workers' Day provides an opportunity to study how labor contributes to society.

Nearly every modern economic system depends on the work of large numbers of people performing different roles. Workers produce food, construct buildings, transport goods, educate students, provide health services, maintain computer systems, manufacture products, conduct research, provide entertainment, operate infrastructure, and perform many other forms of labor.

The relationship between workers, employers, consumers, governments, and technologies creates continuing questions about how work should be organized.

These questions can include:

How many hours should people work?
How should wages be determined?
What working conditions should be legally required?
What rights should workers have to organize?
What obligations should employers have toward employees?
How should workplace conflicts be resolved?
How should productivity gains be distributed?
How should societies respond when technology eliminates particular forms of work?

International Workers' Day therefore connects historical labor struggles with continuing research about the future of work.

Trade unions and collective action

Trade unions are organizations through which workers attempt to act collectively concerning employment conditions.

Union activities can include negotiating wages and benefits, representing workers in disputes, organizing strikes, participating in politics, providing education, and negotiating collective bargaining agreements.

Supporters of unions argue that collective organization can give workers greater bargaining power when negotiating with large employers. Critics may argue that some union practices can impose economic costs, restrict flexibility, or create conflicts between different groups of workers, employers, and consumers.

These competing claims can be examined empirically. Researchers can compare wages, productivity, workplace safety, employee turnover, economic growth, employment levels, and other outcomes across different workplaces and legal systems.

International Workers' Day provides an opportunity to study these questions without assuming that every labor organization, employer, or economic policy produces the same results.

The changing future of work

The meaning of work continues to change as technology changes.

Automation, robotics, artificial intelligence, remote work, global supply chains, digital platforms, and new forms of independent contracting may substantially change labor markets.

Some technologies can eliminate particular jobs while creating new forms of employment. Increased productivity can potentially produce greater material abundance, but it can also create economic disruption when people lose established sources of income.

Questions concerning universal basic income, shorter workweeks, employee ownership, cooperatives, profit sharing, automation, and post-scarcity economics can therefore be connected with the broader history of labor movements.

The eight-hour-day movement itself demonstrates that arrangements that appear normal in one historical period may later change substantially.
