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!

三 | 本届科学运动会以“好奇心、想象力、探求欲,做中学、用中学、创中学”为主题,吸引了全省近3000名中小学生参与45个赛项的角逐。值得一提的是,这次大赛对竞赛项目设置进行了优化升级,在保留科学探究、工程技术、航空航天、人工智能四大常规项目的基础上,增设了创意挑战项目,包含科学表演、无人机侦查、智能轨道赛车、水中机器人等10个特色子项。

四 | 这些项目打破了学科壁垒,将科学知识与艺术表达、传统文化、前沿科技深度融合,不仅考查学生的动手实践能力,更注重考查创新思维、团队协作和跨学科综合素养。去年以来,广泛开展的省、市、县、校四级科学运动会,不仅为省中小学生搭建了学以致用、以赛促学的平台,还是对省在“双减”中做好科学教育加法成效的检验。

五 | 科学教育是提升全民科学素质、建设教育强国、实现高水平科技自立自强的重要基础。传统科学教育往往局限于课本理论与实验室验证,而科学运动会将抽象的物理、数学、编程知识转化为具象的竞技项目,使学生在真实情境中应用知识,实现了从“想法创意”到“科学成果”的闭环。近日,教育部发布《义务教育阶段科学教育“做中学”领航行动指南》,针对重知识传授、轻能力培育的问题,明确整合、拓展、深化现有科学类课程,聚焦“真实问题”,开展跨学科项目式学习。同时,以此为支点,推动科学教育育人方式变革,引领学生关注生产生活实际和科技发展前沿、大胆探索,引导学生成为问题提出者、方案设计者、问题解决者。在此背景下,如何打通科学教育“最后一公里”,重塑义务教育科学课堂,成为当前各级教育部门和学校的一道必答题。

六 | 省教育厅等九部门专门印发《关于加强新时代中小学科学教育工作的实施方案》,强化科学教育助推“双减”的资源供给和服务能力,全省所有县(市、区)科学教育实验载体实现全覆盖。为盘活社会科普资源,省教育厅、省科协等单位联合打造了“知了”科普地图数字化平台,系统整合科技馆、博物馆、重点实验室等各类科普场所,实现“一图览尽”便捷服务。同时,大力推动高校科研设施开放,全省已有40余所高校的近百个实验室和科普基地面向中小学生开放,极大丰富了科学教育的社会大课堂。此外,通过公开招聘、定向培养、在职进修等多种途径,着力优化队伍结构,全省中小学科学类课程专任教师中拥有硕士及以上学历者近万人。实施科学教师能力提升工程,建立省级科学教师培训基地,年均轮训科学教师1.2万人次。通过“科普专家进校园”“科学副校长”等机制强化师资软实力,为青少年科学素养的提升筑牢根基。省教育厅相关负责人表示,将进一步建立健全四级科学竞赛联动机制,开展中小学科技教育和科学教育协同发展改革试点,让更多孩子爱上科学。(日报记者 王敬照)。
