Labor Day


Why Do We Celebrate Labor Day?

Labor Day, an annual celebration of workers and their achievements, originated during one of American labor history’s most dismal chapters.


In the late 1800s, at the height of the Industrial Revolution in the United States, the average American worked 12-hour days and seven-day weeks in order to eke out a basic living. Despite restrictions in some states, children as young as 5 or 6 toiled in mills, factories and mines across the country, earning a fraction of their adult counterparts’ wages.


People of all ages, particularly the very poor and recent immigrants, often faced extremely unsafe working conditions, with insufficient access to fresh air, sanitary facilities and breaks.


As manufacturing increasingly supplanted agriculture as the wellspring of American employment, labor unions, which had first appeared in the late 18th century, grew more prominent and vocal. They began organizing strikes and rallies to protest poor conditions and compel employers to renegotiate hours and pay.


How a Deadly Railroad Strike Led to the Labor Day Holiday


Many of these events turned violent during this period, including the infamous Haymarket Riot of 1886, in which several Chicago policemen and workers were killed. Others gave rise to longstanding traditions: On September 5, 1882, 10,000 workers took unpaid time off to march from City Hall to Union Square in New York City, holding the first Labor Day parade in U.S. history.


The idea of a “workingmen’s holiday,” celebrated on the first Monday in September, caught on in other industrial centers across the country, and many states passed legislation recognizing it. Congress would not legalize the holiday until 12 years later, when a watershed moment in American labor history brought workers’ rights squarely into the public’s view. On May 11, 1894, employees of the Pullman Palace Car Company in Chicago went on strike to protest wage cuts and the firing of union representatives.


On June 26, the American Railroad Union, led by Eugene V. Debs, called for a boycott of all Pullman railway cars, crippling railroad traffic nationwide. To break the Pullman strike, the federal government dispatched troops to Chicago, unleashing a wave of riots that resulted in the deaths of more than a dozen workers.

Who Created Labor Day?

In the wake of this massive unrest and in an attempt to repair ties with American workers, Congress passed an act making Labor Day a legal holiday in the District of Columbia and the territories. On June 28, 1894, President Grover Cleveland signed it into law. More than a century later, the true founder of Labor Day has yet to be identified.


Many credit Peter J. McGuire, cofounder of the American Federation of Labor, while others have suggested that Matthew Maguire, a secretary of the Central Labor Union, first proposed the holiday.



History of Labor Day.

Observed the first Monday in September, Labor Day is an annual celebration of the social and economic achievements of American workers. The holiday is rooted in the late nineteenth century, when labor activists pushed for a federal holiday to recognize the many contributions workers have made to America’s strength, prosperity, and well-being.


Who Founded Labor Day?

Who first proposed the holiday for workers? It’s not entirely clear, but two workers can make a solid claim to the Founder of Labor Day title.


Some records show that in 1882, Peter J. McGuire, general secretary of the Brotherhood of Carpenters and Joiners and a co-founder of the American Federation of Labor, suggested setting aside a day for a "general holiday for the laboring classes" to honor those "who from rude nature have delved and carved all the grandeur we behold."


But Peter McGuire's place in Labor Day history has not gone unchallenged. Many believe that machinist Matthew Maguire, not Peter McGuire, founded the holiday.


Recent research seems to support the contention that Matthew Maguire, later the secretary of Local 344 of the International Association of Machinists in Paterson, New Jersey, proposed the holiday in 1882 while serving as secretary of the Central Labor Union in New York.


According to the New Jersey Historical Society, after President Cleveland signed the law creating a national Labor Day, the Paterson Morning Call published an opinion piece stating that "the souvenir pen should go to Alderman Matthew Maguire of this city, who is the undisputed author of Labor Day as a holiday." Both Maguire and McGuire attended the country’s first Labor Day parade in New York City that year.


The First Labor Day.

The first Labor Day holiday was celebrated on Tuesday, September 5, 1882, in New York City, in accordance with the plans of the Central Labor Union. The Central Labor Union held its second Labor Day holiday just a year later, on September 5, 1883.


By 1894, 23 more states had adopted the holiday, and on June 28, 1894, President Grover Cleveland signed a law making the first Monday in September of each year a national holiday.


Public holiday notified on Labour day May 1 2023 across Pakistan.

Across the world in the majority of countries May 1 is associated with labour or workers. It is known as International Workers day in some countries and in other countries it is referred as labour day or world labour day. In Pakistan, May 1 is most commonly known as Labour Day. Like rest of the world in Pakistan as well, people of Pakistan not only celebrate this day but also they enjoy a holiday on the May 1.


This year as well, as usual, the federal government as well as the provincial / regional governments across the country are announcing May 1 as the Public Holiday. This year May 1, the Labour day is coming on Monday, this will make a long weekend, so many will be much more happy.

Some can get away for three days while others can take a day out from three for rest. However, for many these holidays will act as an opportunity to rest and lower the stress of hectic weekly schedule.


On May 1, all educational institutions including schools, colleges and universities will remain close. Additionally, all banks and offices will also remain close. Educational institutions have also already started notifying students and their parents regarding the May 1, 2023 holiday.


By the way, May 1, the labour day, was also already the part of Schools and Colleges holidays for year 2023 as well as the public holidays for year 2023 which is applicable on the banks, offices and any other kinds of workplaces.
