Four-Day Work Week Is About to Become a Reality in Brazil, Bringing Amazing Benefits Such as More Health, Productivity, and Quality of Life. The Proposal Could Completely Transform the Work Environment, Without Salary Loss.
The proposal to reduce the workweek to four days, present in Bill 1105/2023 and advocated by Senator Weverton (PDT-MA), has generated great interest and various discussions about its impacts on productivity, quality of life, and the economy.
This project aims to shorten the workweek without salary cuts, aligning with similar models already tested in countries like Iceland, the United Kingdom, and, more recently, Chile.
In Brazil, this debate gains even more relevance considering that 44 hours per week is the legal standard, which leads many professionals to overload and issues related to mental health.

Benefits of a Shorter Workweek
Bill 1105/2023 emphasizes that reducing the weekly workload brings positive impacts on the physical and mental health of workers.
Experts point out that shorter workweeks reduce stress and avoid problems such as Burnout syndrome, which is quite common in sectors that demand high productivity over long hours.
According to data from The 4-Day Week Global, a trial conducted in the United Kingdom, 79% of four-day workers reported fewer Burnout symptoms, and over 50% noticed improvements in managing their personal and professional lives.
This model also resulted in lower turnover in participating companies, benefiting businesses and increasing employee satisfaction.
In addition to promoting health, the four-day workweek provides more time for leisure and family interaction, which enhances satisfaction and can reflect a healthier and more productive work environment.
In Brazil, the success of the pilot project by the organization “4 Day Week Brazil,” which follows the 100-80-100 model (100% of salary, 80% of working hours, and maintaining 100% of productivity), reinforces the proposal’s potential for sectors that prioritize efficiency and quality of life.
Challenges for Implementation in Brazil
Despite the advantages observed in other countries, implementing a reduced workweek in Brazil is not an easy task.
The diverse reality of the national market requires a plan for adaptation and support, especially for small and medium-sized enterprises (SMEs), which could face difficulties adjusting operations without financial impacts.
Another barrier is the productivity culture tied to long working hours, which still persists in many sectors. According to technician Clemente Ganz Lúcio from the Central Trade Union Forum, the success of the proposal in Brazil depends on the adoption and adaptation of various companies, as well as support for SMEs to adjust without significant impacts.
Economic Effects and Role of Labor Unions
Besides challenging conventions in the corporate environment, reducing the workweek also raises economic questions.
Critics argue that fewer hours worked could impact production and, consequently, the economy.
On the other hand, supporters of the bill argue that with more free time, workers could increase consumption, benefiting sectors such as tourism and leisure.
This effect could create new jobs and stimulate the economy more broadly, an argument used by other countries that are already discussing or adopting shorter workweeks.
In the national context, unions and associations play a central role in ensuring that the reduction of the workweek is fair, maintaining labor rights and preventing work overload.
Senator Paulo Paim (PT-RS), the project’s rapporteur, emphasizes the need for consensus among employers, employees, and the government to effectively implement a reduced workweek.
The labor movement supports this change as long as there is a fair redistribution of productivity gains, allowing greater access to jobs and preventing the accumulation of functions for those who remain employed.
Lessons from International Experiences
The experience in Iceland was one of the most discussed in the global context. There, the four-day week did not reduce productivity; in some cases, it increased it.
The United Kingdom and Chile are following the same path, gradually adapting the working hours. Brazil, with the support of international organizations, views the Icelandic model as a positive and viable example.
In a recent trial, nearly all British companies decided to maintain the new regime after finding that there was no drop in productivity, but rather improvements in employees’ mental health and an increase in talent retention.
And the Future of Work in Brazil?
While the project awaits processing in the Chamber of Deputies, the debate intensifies across various sectors of Brazilian society, with many workers and experts closely watching global initiatives and local adaptations.
The change could represent a new era for the job market, aligning well-being and productivity in an innovative way.
Is Brazil ready to take a bold step and reduce the workweek, as other countries have done?
