Have We Forgotten the True Meaning of Labor Day?_我的网站
一 |
Labor Day is a U.S. national holiday held the first Monday every September. Unlike most U.S. holidays, it is a strange celebration without rituals, except for shopping and barbecuing. For most people it simply marks the last weekend of summer and the start of the school year.
The holiday’s founders in the late 1800s envisioned something very different from what the day has become. The founders were looking for two things: a means of unifying union workers and a reduction in work time.
The first Labor Day occurred in 1882 in New York City under the direction of that city’s Central Labor Union.
In the 1800s, unions covered only a small fraction of workers and were balkanized and relatively weak. The goal of organizations like the Central Labor Union and more modern-day counterparts like the AFL-CIO was to bring many small unions together to achieve a critical mass and power. The organizers of the first Labor Day were interested in creating an event that brought different types of workers together to meet each other and recognize their common interests.
However, the organizers had a large problem: No government or company recognized the first Monday in September as a day off work. The issue was solved temporarily by declaring a one-day strike in the city. All striking workers were expected to march in a parade and then eat and drink at a giant picnic afterwards.
Why was Labor Day invented?
Labor Day came about because workers felt they were spending too many hours and days on the job.
In the 1830s, manufacturing workers were putting in 70-hour weeks on average. Sixty years later, in 1890, hours of work had dropped, although the average manufacturing worker still toiled in a factory 60 hours a week.
These long working hours caused many union organizers to focus on winning a shorter eight-hour work day. They also focused on getting workers more days off, such as the Labor Day holiday, and reducing the workweek to just six days.
These early organizers clearly won since the most recent data show that the average person working in manufacturing is employed for a bit over 40 hours a week and most people work only five days a week.
As the U.S. economy expanded beyond farming and basic manufacturing in the late 1800s and early 1900s, it became important for businesses to find consumers interested in buying the products and services being produced in ever greater amounts. Shortening the work week was one way of turning the working class into the consuming class.
The common misconception is that since Labor Day is a national holiday, everyone gets the day off. Nothing could be further from the truth.
While the first Labor Day was created by striking, the idea of a special holiday for workers was easy for politicians to support. It was easy because proclaiming a holiday, like Mother’s Day, costs legislators nothing and benefits them by currying favor with voters. In 1887, Oregon, Colorado, Massachusetts, New York and New Jersey all declared a special legal holiday in September to celebrate workers.
Within 12 years, half the states in the country recognized Labor Day as a holiday. It became a national holiday in June 1894 when President Grover Cleveland signed the Labor Day bill into law. While most people interpreted this as recognizing the day as a national vacation, Congress’ proclamation covers only federal employees. It is up to each state to declare its own legal holidays.
Moreover, proclaiming any day an official holiday means little, as an official holiday does not require private employers and even some government agencies to give their workers the day off. Many stores are open on Labor Day. Essential government services in protection and transportation continue to function, and even less essential programs like national parks are open. Because not everyone is given time off on Labor Day, union workers as recently as the 1930s were being urged to stage one-day strikes if their employer refused to give them the day off.
In the president’s annual Labor Day declaration last year, Obama encouraged Americans “to observe this day with appropriate programs, ceremonies and activities that honor the contributions and resilience of working Americans.”
The proclamation, however, does not officially declare that anyone gets time off.
Controversy: Militants and founders
Today most people in the U.S. think of Labor Day as a noncontroversial holiday.
The first controversy that people fought over was how militant workers should act on a day designed to honor workers. Communist, Marxist and socialist members of the trade union movement supported May 1 as an international day of demonstrations, street protests and even violence, which continues even today.
More moderate trade union members, however, advocated for a September Labor Day of parades and picnics. In the U.S., picnics, instead of street protests, won the day.
There is also dispute over who suggested the idea. The earliest history from the mid-1930s credits Peter J. McGuire, who founded the New York City Brotherhood of Carpenters and Joiners, in 1881 with suggesting a date that would fall “nearly midway between the Fourth of July and Thanksgiving” that “would publicly show the strength and esprit de corps of the trade and labor organizations.”
Later scholarship from the early 1970s makes an excellent case that Matthew Maguire, a representative from the Machinists Union, actually was the founder of Labor Day. However, because Matthew Maguire was seen as too radical, the more moderate Peter McGuire was given the credit.
Who actually came up with the idea will likely never be known, but you can vote online here to express your view.
Have we lost the spirit of Labor Day?
Today Labor Day is no longer about trade unionists marching down the street with banners and their tools of trade. Instead, it is a confused holiday with no associated rituals.
The original holiday was meant to handle a problem of long working hours and no time off. Although the battle over these issues would seem to have been won long ago, this issue is starting to come back with a vengeance, not for manufacturing workers but for highly skilled white-collar workers, many of whom are constantly connected to work.
If you work all the time and never really take a vacation, start a new ritual that honors the original spirit of Labor Day. Give yourself the day off. Don’t go in to work. Shut off your phone, computer and other electronic devices connecting you to your daily grind. Then go to a barbecue, like the original participants did over a century ago, and celebrate having at least one day off from work during the year!

Chinese scientists have developed a “brain-reading” AI model that could help predict the risk of depression among adolescents up to four years in advance by analyzing how humans respond to facial expressions, a technology expected to inspire future development of embodied intelligent humanoids capable of perceiving human emotion and thoughts through nuanced facial cues.
WHO data show that around 332 million people worldwide have depression, about one-third of whom have treatment-resistant forms of the condition. In China, an estimated 95 million people suffer from depression, National Business Daily reported, citing statistics from the China Mental Health Survey.
Using data from a population-based longitudinal adolescent cohort recruited across several European countries, the research team led by Lu Han, assistant professor at the School of Artificial Intelligence, Shenzhen University, has built an AI model that predicted which 19-year-olds were more likely to develop depression at the age of 23. The predictions were backed up by an independent clinical cohort of individuals with depression. The team’s paper was published in the journal Science Advances this month.
According to Lu, the study used brain scans taken at age 19 to predict depression-related symptoms at age 23. The study focuses on adolescence because the transition from adolescence to early adulthood is a key developmental period when depressive symptoms can increase rapidly. The earlier risks are identified, the greater the opportunity for prevention, Lu told the Global Times on Monday, adding that the findings need to be further validated in middle-aged and older adults and across different ethnic groups in future research.
In this study, the researchers analyzed data from adolescents in the IMAGEN, a population-based longitudinal cohort recruited across several European countries. At age 19, participants underwent an fMRI emotional-face task, and their emotional symptoms were assessed using standardized questionnaires. Genetic data obtained from blood samples were also analyzed, and participants were followed up at age 23. The researchers examined whether neural representations of angry faces at age 19 were associated with emotional symptoms and could predict elevated emotional symptoms four years later.
According to Lu, people without depression can more easily distinguish emotional changes based on others’ facial expressions and respond accordingly – for example, responding with friendliness to a smiling expression. But people with depression cannot do this, and are more likely to assume people are angry with them.
A brain-aligned deep-learning model developed by Lu’s team suggested that those participants whose brains were less able to distinguish between different facial emotions and tended to perceive others as angry were more likely to develop symptoms of depression and anxiety in adulthood.
The hypothesis that adolescents at risk of depression may respond differently to other people’s facial expressions than those without such risk based on the negative information processing bias long observed in depression research: people at risk of depression are more likely to notice, interpret, or remember negative social information, Lu said.
The researchers focused on angry facial expressions because they signal social threat and rejection, which are closely linked to interpersonal difficulties and negativity bias associated with depression. They hope to further understand how this bias develops within the visual system.
Building on this, they created a deep learning model, which mimics how the brain processes visual information, to predict how the brain encodes abstract emotional concepts such as anger.
They found that 19-year-olds whose response to facial expressions was skewed in favour of negative emotions or memories were the most likely to develop some form of depression.
Based on these findings, Lu’s team then developed a marker that can identify possible warning signs.
According to Lu, the study found that the computational biomarker was linked to the depression-related variant rs11123030 and polygenic risk for depression, suggesting that genetic susceptibility may affect emotional perception. It also provided predictive information beyond family stress and socioeconomic factors, complementing rather than replacing environmental risk factors. Therefore, depression is neither purely genetic nor purely psychological, but a complex mental disorder arising from the interplay of genetic susceptibility, brain development, emotional and cognitive processes, and life experiences.
According to Lu, the study is also expected to advance AI by aligning deep neural networks with human brain activity and using parameter perturbations to probe neural mechanisms, allowing models to both predict and explain how biases may arise.
The findings suggest that future affective computing and embodied AI should go beyond simply labeling facial expressions, incorporating visual details while preventing prior assumptions from overriding real-time sensory input, Lu said, adding that the findings could provide valuable insights for developing more interpretable robotic perception systems that more closely emulate the way humans process emotions.
