Countries Trialing a Four Day Week in 2025

A growing list of countries has begun experimenting with four-day workweeks to improve efficiency and combat rising rates of burnout and stress among employees.
Although none have implemented the change nationwide as policy, many trials are ongoing in the private and public sector, and could inaugurate a change in how companies across the globe think about productivity, employee wellbeing, and workplace culture.
"The four-day week offers significant benefits for both workers and organisations," said Rita Fontinha, professor of Strategic Human Resource Management at Henley Business School and a frequent researcher into the feasibility of a four-day working week.
Which Countries Are Trialing a Four-Day Workweek in 2025?
Newsweek found that three countries are currently involved in some form of four-day workweek trial, in which employees are offered the same financial compensation despite the reduced hours.
Japan
As of April, the Tokyo Metropolitan Government has offered its employees the option to work four-day weeks under the 100:80:100 model – in which they will receive the same pay despite working only 80 percent of the hours, but are expected to maintain 100 percent productivity.
This change is intended to improve flexible working arrangements for Japan's women and is linked to a broader push to address the country's ongoing fertility crisis.
"We will continue to review work styles flexibly to ensure that women do not have to sacrifice their careers due to life events such as childbirth or child-rearing," said Tokyo Governor Yuriko Koike in December, quoted by The Japan Times.
United Arab Emirates
A public-sector pilot is currently taking place in Dubai as part of the city's "Our Flexible Summer" initiative. Set to run from the beginning of July to mid-September, the scheme follows a successful trial from 2024. Two groups of government employees across several entities will have their days and hours adjusted as part of the program: The first will work eight-hour days from Monday to Thursday, while the second will work seven-hour days from Monday to Thursday, and four-and-a-half hours on Friday.
Portugal
A government-backed pilot of the four-day workweek is currently taking place in the Azores Autonomous Region. According to The Portugal News, the Azorean government believes the public sector trial will increase productivity and could be expanded to the private sector.
Rita Fontinha, who is currently coordinating the Azores study, told Newsweek that these ongoing cases "are generating important comparative data and show that the model may be adaptable across diverse sectors and institutional contexts."
What Are the Benefits of a Four-Day Workweek?
Fontinha, who has been involved in several studies of the four-day workweek, believes the change contributes to significant improvements in employee wellbeing, as well as benefits for employers, who are able to better attract and retain talent, and reduce inefficiencies caused by employee burnout.
"For workers, we found improved work-life balance, better mental health (including reductions in stress, burnout, anxiety, and insomnia), higher job satisfaction, and improved performance—as reported by both employees and their supervisors," she said. "For organisations, our findings show increased productivity at the collective level, as well as improvements in revenue and profit. These financial gains are linked to reduced absenteeism and turnover, and a stronger ability to attract and retain talent—resulting in long-term savings in human resource management."

Recent studies have confirmed these findings. One of the largest trials yet, involving nearly 3,000 employees and 141 organizations across six countries, published its results from a six-month experiment last week. Employees reported increased job satisfaction as well as improved mental and physical health, without major losses of productivity.
A previous study conducted in the U.K. found similar improvements in employee wellbeing, with no noticeable decline in revenue over the six-month period.
And, despite the skepticism some companies may have harbored over involving themselves in these studies, a vast majority in both chose to keep the policy in place even after the end of the trial period.
B Lab U.S. & Canada, a regional partner of the nonprofit B Lab Global, made the switch to four-day workweeks in 2023. Members of the team that implemented this change told Newsweek that this had delivered "both quantitative and qualitative gains."
"93 percent of our staff are reporting better work-life balance, reduced burnout, and 73 percent are reporting a stronger sense of autonomy," they said, citing the results of the company's most recent internal survey. "From an employer perspective, it has prompted sharper prioritization, reduced meetings, and boosted focus, all without sacrificing output."
"If anything, productivity has improved," they added. "The transition to a four-day week encouraged teams to strip back nonessential meetings and focus on work that truly drives impact."
However, they noted that finding success with this change requires "thoughtful implementation and internal alignment, not just schedule changes," and that widespread adoption will continue to be inhibited by "deeply ingrained assumptions" about work and productivity that are currently baked into corporate culture.

Why the Plastic Treaty Talks Now Underway Are a Chance for Climate Action
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. It was the images of plastic waste clogging rivers, covering shorelines and killing marine wildlife that helped to galvanize world leaders three years ago to start work on a global treaty to reduce the glut of plastics. But there is also a less visible form of pollution from plastics taking a toll on our atmosphere—the massive amount of greenhouse gases generated by plastic production. That's why the work underway this week in Geneva, Switzerland, to finalize a plastics treaty is a significant opportunity to address climate change. Plastics and the petroleum used to produce them are responsible for roughly 5 percent of the world's industrial greenhouse gas emissions—more than the emissions from the aviation sector. Without intervention, climate scientists warn, the growth of plastics will drive those emissions higher, making it far more difficult to meet international targets to prevent the worst warming. "Decarbonizing the plastics sector is essential for staying within safe climate limits," Pablo Blasco Ladrero, a researcher at the non-profit organization NewClimate Institute, told Newsweek via email. Ladrero is a co-author of a new report on plastic's climate impacts. As oil demand for power and transportation level off, the plastics and petrochemicals industries are becoming a more important market. Efforts to reduce plastics "directly challenge fossil fuel interests, contributing to the stalemate in negotiations,'... As oil demand for power and transportation level off, the plastics and petrochemicals industries are becoming a more important market. Efforts to reduce plastics "directly challenge fossil fuel interests, contributing to the stalemate in negotiations,' according to Pablo Blasco Ladrero, at the NewClimate Institute. More Photo-illustration by Newsweek/Getty If the world's production of plastics continues on its current trajectory, Ladrero said, it would account for a much larger portion of the carbon we could emit while staying on course to meet the most ambitious targets under the Paris Climate Agreement. "By mid-century, plastics alone could consume 26 percent to 31 percent of the remaining carbon budget," he said. A global plastics treaty holds the promise of an elegant solution that addresses multiple environmental challenges at once. Limiting plastic production could help reduce the emissions warming our planet, the trash fouling our oceans and even the microplastics coursing through our bodies. But doing so will involve overcoming opposition from some of the world's wealthiest and most powerful political interests. A Role for Recycling The last round of talks on the global plastics treaty ended in stalemate when a handful of petroleum-producing countries objected to a cap on plastic production. While many observers of the treaty process told Newsweek they still hope for a strong outcome from the talks now underway, many of them voiced skepticism about chances for any meaningful limit on plastics. "I'm 60 percent [sure] that we will have a treaty," Steve Alexander, president and CEO of the Association of Plastic Recyclers, said during a Newsweek panel discussion last month. "I'm much less optimistic we'll have a treaty with any lasting teeth to it," he said. Another member of the panel, Professor Douglas McCauley, directs the Benioff Ocean Science Laboratory at the University of California, Santa Barbara. McCauley and his colleagues have modeled the potential effects of policies to rein in plastic waste and what the future will look like if we stay on the business-as-usual trajectory. "Emissions increase immensely with business as usual, because we continue to extract oil and gas," McCauley said. "It's a 37 percent increase in emissions over where we're at right now." In work published in the journal Science in December, McCauley and his co-authors found that without global policy intervention, greenhouse gas emissions related to plastics would rise to 3.35 gigatons by 2050. That's about the same as the emissions from 9,000 natural gas-fired power plants operating for a year. Capping global virgin plastic production at 2020 levels would be the best way to drive down both plastic waste and greenhouse gases from plastic, he said. But a cap on plastic production is not the only option in play at the talks in Geneva, and McCauley's team found other policies could also reduce emissions. A global mandate for plastic products to include a minimum of 40 percent recycled content could also take a big bite out of greenhouse gases. "When you use recycled material, you reduce energy utilization versus using virgin material by almost 80 percent," Alexander said. "You reduce your greenhouse gas emissions by a similar amount." Counting on Consumer Sentiment Current global recycling rates for plastic hover at just under 10 percent. And while recycling can cut waste and emissions, it won't eliminate them. "Recycling will not solve the crisis we're in when it comes to plastic," CEO of Elopak Thomas Körmendi told Newsweek. "We need to find alternatives." Oslo-based Elopak is in the alternative packaging business, providing fiber-based cartons to major food and household product companies in more than 40 countries. Elopak will be a participant in Newsweek's upcoming "Pillars of the Green Transition" event on September 24th during Climate Week NYC. Elopak commissioned a life cycle assessment study of the carbon emissions associated with different types of beverage containers, including the production and disposal of the packaging and energy required for shipping. Fiber cartons were found to produce about a third less CO2 than HDPE plastic bottles and about 60 percent less than bottles made from PET plastic. Körmendi said client companies that have set ambitious climate goals find that attractive, and in some markets, such as the European Union, new regulations on plastic packaging make alternatives such as cartons more appealing. A strong global treaty on plastics could help to level the playing field elsewhere by holding plastic packaging producers and users accountable for the environmental costs that are now foisted onto the public. But Körmendi said he is not optimistic about the product that will emerge from the Geneva talks. Instead, he said, he puts more faith in the rapidly changing consumer attitudes about plastic. "There is a very strong consumer sentiment everywhere, including in the U.S. by the way, that we want to reduce our plastic consumption," he said. The visceral public reaction to the visible plastic waste is what will ultimately drive down both plastic garbage and greenhouse gases. "It is just something that is very visual and, I think, emotionally disturbing," Körmendi said. "I find probably that is a stronger motivation than waiting for global treaties to be signed." Plastics, Pollution and Petroleum Politics The connection between plastics and petroleum has also created a powerful political bloc that has stymied efforts for a strong treaty. Late last year at talks in Busan, South Korea, oil-producing nations led by Russia and Saudi Arabia objected to language that would cap the overall production of new plastic and thus limit an important growth market for oil and gas.

Mark Felix/AFP via Getty Images As deployment of renewable electricity sources grows and electric vehicles (EVs) gain traction in the global market, the International Energy Agency forecasts that oil demand will level off, raising the importance of petrochemicals. "Plastics have become a crucial growth market for fossil fuels, especially as demand in traditional sectors like road transport and power generation is projected to decline in the coming decades," Ladrero of the NewClimate Institute said. "Efforts to decarbonize plastics directly challenge fossil fuel interests, contributing to the stalemate in negotiations." On Thursday, the nonprofit Center for International Environmental Law released an analysis of participants in the Geneva talks that identified 234 fossil fuel and chemical industry lobbyists registered to attend, the highest at any negotiation for the plastics treaty. Industry lobbyists outnumber the combined diplomatic delegations of all 27 European Union nations. "The treaty meant to stop plastic pollution is being shaped by those who profit from it," Dylan Kava, strategic engagement and communications lead for the Pacific Islands Climate Action Network, said at a press event in Geneva. As the talks approached the halfway point on Friday, civil society groups issued a statement that the process was "not on track" to deliver an acceptable result. "The same, tired tactics are still causing gridlock at the negotiating table," Erin Simon, vice president of plastic waste and business for the World Wildlife Fund, said in an email from Geneva. "If we can't turn this around, we risk leaving Geneva either empty-handed or with an empty treaty."

Student Loan Update: New Plan Rolled Out to Help 1.4 Million Borrowers
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. A new student loan reduction plan will be available to 1.4 million borrowers in New York City. Mayor Eric Adams on Thursday announced the loan reduction and college savings assistance program, which also offers specialized assistance for 1.6 million parents and guardians in lowering the costs of a college education. Why It Matters The program will help many borrowers who contribute to America's $1.8 trillion in student loan debt. Since President Donald Trump's One Big Beautiful Bill Act was signed into law last month, the Department of Education will abolish the SAVE program and other income-driven repayment (IDR) options by July 2028. Borrowers currently on SAVE will be transitioned to new plans, either the Repayment Assistance Plan (RAP), which is slated to launch by July 2026, or a revised Standard Repayment Plan. However, these plans typically offer higher monthly payments and may make it more difficult for borrowers to afford basic necessities. "Student loan programs have become overly complex, and the recent changes by the current administration have only made things worse," Kevin Thompson, CEO of 9i Capital Group and host of the 9innings podcast, told Newsweek. "Borrowers are struggling—many are in default, and some can't even access the federal loan portals they need. NYC is stepping up to reduce the burden, especially for public sector workers, by offering real solutions to lower debt and simplify the repayment process." New York City Mayor Eric Adams speaks during a news conference at City Hall on June 26. New York City Mayor Eric Adams speaks during a news conference at City Hall on June 26. Michael M. Santiago/Getty Images What To Know The student loan reduction and college savings assistance program will be available to all New York City residents, estimated to help them save a collective $1 billion. Since the city partnered with student loan platform Summer, city residents who work as public servants have lowered their debts through the federal government's income- driven repayment plans and the Public Service Loan Forgiveness program. Now the program will be available to another roughly 1.4 million New Yorkers who either already have student loan debt or are enrolling in college. "Anyone who lives in the city's five boroughs with student debt or who is planning for college can access Summer's platform for free, thanks to the city's sponsorship," Will Sealy, CEO and founder of Summer, told Newsweek. "In addition to providing financial relief, this program also removes the administrative burden on people who are trying to access loan assistance, scholarship programs, and other ways to save on college costs. We've already helped thousands of NYC employees determine their eligibility for and enroll in forgiveness programs because we've simplified the process." Parents and guardians in particular will also get specialized assistance. The city estimates the program will reduce student loan payments for New Yorkers by an average of $3,000 per year and $7,000 per year for those with advanced degrees. "Leading a financially healthy life is a difficult task when you are tackling student loan debt — something I know firsthand," Department of Consumer and Worker Protection Commissioner Vilda Vera Mayuga said in a statement. "With this new expansion, we are extending support to millions of New Yorkers who have or are thinking of taking on student loans." In the first three months of the city employee loan program, New Yorkers saw $13.8 million in savings and an average reduction of $3,800 in annual student loan payments. The pilot program was originally announced in May to help city employees take advantage of the Public Service Loan Forgiveness program, but now all New York City residents qualify to use Summer's online portal. Through this portal, you can verify your eligibility for programs that lower payments, compare repayment options and manage paperwork for enrolling in federal programs. On the college planning side, residents will have access to online tools to figure out how much they need to save and strategies to make higher education more affordable. Michael Ryan, finance expert and founder of said the program is a "smart move" by the local government, especially as it looks to keep young talent in the city. "Mayor Adams is focused on his admin's push to make the city family friendly," Ryan told Newsweek. "It's not altruism; it's to keep young talent from fleeing NYC to cheaper, more affordable places." What People Are Saying Adams, in a statement: "Getting an education shouldn't lead to a lifetime of debt; yet, for far too many New Yorkers, getting a college degree and a higher education means more bills, more debt, more money out of their pockets... Working with Summer, we will expand our groundbreaking partnership and help millions of New Yorkers bring down their monthly student loan payments by thousands of dollars and save even more on the cost of a college degree. We are lowering costs for families, helping them connect to debt relief, and making our city the best place to find opportunity, raise a family, and live the American Dream." Sealy, in a statement: "Student loan repayment and college cost planning are increasingly complex processes to navigate. Thankfully, the City of New York is stepping up to provide additional access to resources, tools, and programs to reduce that complexity." Thompson also told Newsweek: "Whether this becomes a model for other cities depends on the political climate. It's unlikely red states adopt anything close to this. They're more aligned with the administration's stance on repayment. But in blue or more progressive-leaning areas, this could absolutely catch on. That said, don't be surprised if this ends up being another battleground in the courts." What Happens Next As the first program of its kind for any major U.S. city, Sealy said Adams and the New York City government are setting a larger example for what other cities can do to improve affordability for residents. "This public-private model lets other cities leverage existing expertise without building from scratch," Sealy said. "Student debt affects local workforce retention and economic development. Cities don't need to wait for D.C. to take action when they have the tools to help their own residents today. Many other large municipalities already have similar programs of their own in the works, which we're excited to support."

Donald Trump Removes IRS Chief, Temporarily Replaces Him With Scott Bessent
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. President Donald Trump has removed Billy Long, the head of the Internal Revenue Service (IRS), and temporarily replaced him with Treasury Secretary Scott Bessent, The Associated Press and New York Times reported on Friday. Long's removal comes less than two months after he was confirmed to lead the federal agency. Bessent will take over as the head of the IRS on an acting basis, a White House official told AP. The Republican-led Senate confirmed Long 53-44 despite Democratic senators' concerns about Long's lack of experience in tax administration and his past work for a firm that pitched a fraudulent pandemic-era tax break. People familiar with the matter told the Times that Long is expected to be nominated for an ambassadorship. Five people have served as IRS commissioner, on a permanent or an acting basis, since Trump took office: Douglas O'Donnell, Melanie Krause, Gary Shapley, Michael Faulkender and Long. O'Donnell took over leading the agency on January 21, after his predecessor, Danny Werfel, announced he would leave the agency before Trump was inaugurated. This is a breaking news story. Updates to follow.
