The 4-day work week in Portugal: is it really happening?

5 min readMar 3, 2023

That was back in 1940. Since then, visionary leaders, courageous workers and revolutionary new technologies have redefined the concept of work — but we are likely just getting started. Studies point out that nearly half of the occupations in the United States could be automated within 20 years. This poses huge economic and social challenges. Many countries — Portugal included — are floating the idea of a 4-day work week as a response to greater productivity at work. Some areas of public service and a few private companies are already making headway and managers and workers alike seem happy with initial results. Could the future of work be doing less of it, but more efficiently?

What are the pros of a 4-day workweek?

Most workers react positively to the prospect of a 4-day work week, which means that they will effectively have one extra day to spend with family, children, to catch up on housework, to dedicate to personal projects, or simply to rest and recover. Like any other benefit, this is sure to increase motivation at work and means that workers can be more focused while they are at work.
As a result, workers on a 4-day workweek are likely to be more productive — or at least get the same amount of work done.

In a recent study by researchers at Cambridge and Oxford universities with over 70 companies and 3,000 employees, around 85% of organisations say they were “likely” or “extremely likely” to continue the four-day model after the trial period ends. Impressively, 95% of companies reported that productivity had either remained the same or had improved. In simple language, what this means is that less can be more. People were working 20% fewer hours, yet were sufficiently motivated to enable most of the participating organizations to achieve just as much productivity as with a traditional five-day workweek.

Also, happy workers means less turnover. The better the employees feel at work, the more loyal they’ll be to their employers.Millennials and generation Z workers, who make up the bulk of the workers — tend to prioritise work-life balance when choosing a place to work, namely companies that focus on mental health and wellbeing, as well as workplace flexibility.

One aspect of the traditional workweek that is frequently overlooked is how it promotes inequality, specifically gender inequality among parents. Childcare and housework specifically still tend to fall more on women. With a smaller work week, childcare needs would represent a lower financial burden for parents, allowing for both parents to work equally, for example.

What are the cons of a 4-day workweek?

The premise of a 4-day work week is to maintain or increase productivity while at work. In practice, this means doing more work in less time. While this may be viable for some people, it can be a contributing factor to stress or burnout for others. In the case that the workers aren’t able to increase their productivity to match the 5-day week, overtime may be needed to compensate for the gap.
Another key downside is that not all business models are compatible with a 4-day work week. In certain areas, additional workers will be necessary to cover the extra day off — offsetting the potential benefits for companies. That is the case with most industrial or service-oriented businesses. A generalized shift to 4-day weeks can also increase social inequality between knowledge workers and manual labour jobs. What will society look like when nurses work 5-day weeks and marketing workers wrap it up in just 4 days? And how will an already stretched national budget cope with the need to hire 20% extra workers?

As with anything new, there are still a lot of unknowns about the 4-day workweek and its consequences. But some countries have begun trials that could determine what work looks like in the next decades.

How the 4-day work week is being rolled out around the world

The 4-day workweek isn’t a new concept. It has been talked about at least since 2010 and has met with a fair share of criticism from the start. However, innovation is part of what keeps the world spinning, so although no country has officially adopted a 4-day work week yet, many countries are experimenting with it.

Currently, at least 18 countries are taking part in reduced work weeks. Countries like Japan, Spain, and Scotland all have ongoing government-funded programs to incentivise 4-day workweek trials. Dozens of companies in Australia, Canada, Germany, Ireland, South Africa, the United Kingdom, and the United States are giving the 4-day work week a go, with pilot trials of a few months.

The results were overwhelmingly positive: companies reported increased revenue and improved employee health and well-being and had a positive impact on the environment. And after the success of the initial pilots, more companies that together employ thousands of people are considering or are already implementing the same approach.

What about Portugal?

In Portugal, there have been a few companies experimenting with the 4-day workweek but a new, broad-scoped pilot is scheduled to start in 2023 and last for about 6 months. Currently, there are about 63 Portuguese companies interested in participating in the pilot, financed by the Portuguese Institute of Employment and Professional Formation.

This participation is voluntary and reversible, and the only requirement is that the total weekly hours are reduced. Some companies are going all in with the 32-hour model, but others are being a bit more conservative and reducing the work hours from 40 to 36. The results should be public in November.
