Given the recent changes in relation to flexible working and the Government's plans to make it the "default", this article explores what the advantages and disadvantages are for employers of a four-day week.
Flexible Working
The right of employees to request flexible working, including going onto a four-day week, has been a day one right since the 6th April 2024. Nevertheless, employers have the right to reject such requests on a number of grounds:
- If the proposed changes would have a detrimental effect on the quality or performance of work
- If the employer would incur additional costs that are burdensome to the business
- If the changes would make it more difficult to meet customer demand
- If there is an inability to reorganize work among existing staff or hire additional staff
- If there is insufficient work during the periods the employee proposes to work
- If there are planned structural changes within the organization and the request is incompatible with such changes.
However, as we highlighted in a recent article, the new Labour Government is planning to strengthen employees rights further via its Employment Rights Bill, by making flexible working the "default" from day one for employees except where it is not “reasonably feasible”. In practice, however, how this differs from what the law already is at the moment is somewhat unclear other than it is likely under the new legislation to become more difficult for employers to reject flexible working requests.
Four-Day Week
According to a recent article in the Daily Telegraph, "workers are to be given new rights to demand a four-day week in a law planned for this autumn. The Telegraph understands the system of “compressed hours”, which lets an employee work their contracted week’s hours in four days rather than five, will be included in the package of new rights for workers." That is, if this report is correct, in the Government's endeavours to make flexible working the default, the Employment Rights Bill may possibly include some specific provisions relating to a four-day week
Commenting on the Government's proposals, the Conservative Party's shadow business secretary, Kevin Hollinrake, contended in the same Daily Telegraph article that "Labour must listen to businesses who are petrified about day one employment rights and bringing in the four-day week through the back door. It will be businesses and consumers who pay and growth that suffers if they don’t listen."
In response to this, Baroness Jacqui Smith, the Education Minister, argued on behalf of the Government that "flexible working is actually good for productivity...[Under a four-day week] you're still doing the same amount of work, but perhaps you're doing it in a way that enables you, for example, to need less childcare, to spend more time with your family, to do other things, that encourages more people into the workplace."
So what are the advantages and disadvantages for employers of allowing workers to go onto a four day week?
Advantages
Advocates of a four-day week point to several advantages for employers, including the following:-
- Increased Productivity: Various pilots around the world indicate that a four-day week can lead to increased productivity among employees. With an extra day off, workers return to their jobs more rested and motivated, leading to higher efficiency and better-quality work. Studies indicate that the reduced hours encourage employees to focus better, limit time-wasting activities, and streamline their tasks. This results in a more concentrated effort during working hours, ultimately leading to higher output without extending the overall working time.
- Improved Employee Well-Being: One of the most significant advantages of a four-day week observed in pilots and trials is an improvement in employee well-being. A reduced workweek provides employees with more time for rest, family, hobbies, and personal development. This balance between work and personal life reduces stress levels and decreases burnout rates. Healthier and happier employees are less likely to take sick leave or suffer from chronic stress-related illnesses, which benefits both the individual and the employer by maintaining a steady workforce.
- Higher Quality Recruitments and Enhanced Staff Retention: The four-day week has been found to be a compelling factor in attracting top talent. In a competitive job market, offering a shorter workweek can differentiate an employer from others. Additionally, it helps retain existing employees who may otherwise seek alternative employment opportunities that offer better work-life balance. Companies that have adopted this model report lower turnover rates and higher job satisfaction, creating a more stable and experienced workforce.
- Cost Savings: Employers can achieve significant cost savings by adopting a four-day week. Reduced operational costs such as utilities, office supplies, and maintenance expenses are immediate benefits. Moreover, with fewer days of commuting for employees, there is also an indirect reduction in expenses related to travel subsidies or allowances. Some companies have even reported reduced overtime payments due to increased efficiency during regular working hours.
- Environmental Benefits: A four-day week contributes positively to environmental sustainability. Fewer commutes mean reduced carbon emissions from transportation. Additionally, with some offices being closed an extra day each week, there is less energy consumption for heating, cooling, lighting, and electronic devices. These environmental benefits align with corporate social responsibility goals and can enhance the company's public image as an environmentally conscious organization.

Disadvantages
Nevertheless, critics of a four-day week contend that there are a number of downsides for employers, including the following:-
- Reduced Customer Service Availability: One of the primary disadvantages of a four-day week for employers is the potential reduction in customer service availability. With employees working fewer days, there may be fewer hours during which customers can reach out for support or inquiries. This could lead to dissatisfaction among clients who expect round-the-clock service, especially in industries where timely responses are crucial. Employers might have to either extend hours on the remaining workdays or hire additional staff to cover the gaps, both of which can increase operational costs.
- Compressed Workload and Increased Stress: Another significant concern is the potential increase in stress levels among employees due to compressed workloads. While a four-day week aims to improve work-life balance, the reality is that the same amount of work often needs to be completed in fewer days. This can lead to longer hours on working days and heightened pressure to meet deadlines, potentially negating the intended benefits of reduced working hours. Over time, this increased stress could lead to burnout and reduced overall productivity.
- Implementation Challenges and Costs: Transitioning to a four-day week involves several logistical challenges and costs that employers need to consider. These include restructuring work schedules, renegotiating contracts, and possibly investing in new technologies to maintain productivity levels. Additionally, there may be legal implications related to changing employment terms, which could require consultation with legal experts and result in further expenses. The initial investment required for a smooth transition might be prohibitive for some businesses.
- Potential Decline in Team Collaboration: Effective collaboration and communication are critical components of a productive workplace. A four-day week could disrupt these elements by reducing overlapping working hours among team members. This can make it harder to schedule meetings, share ideas promptly, and maintain cohesive teamwork. In industries that rely heavily on collaborative efforts, such as creative fields or project-based work, this disruption could significantly impact the quality and efficiency of output.
- Difficulty in Measuring Productivity Gains: While proponents of the four-day week argue that it leads to higher productivity, measuring these gains accurately can be challenging for employers. Traditional performance metrics may not capture the nuances of productivity changes brought about by altered working patterns. Employers might struggle to assess whether the reduced hours genuinely contribute to improved efficiency or if perceived gains are merely short-term adjustments that will taper off over time. This uncertainty makes it difficult for businesses to justify the shift without clear evidence of sustained benefits.
Conclusion
The debate surrounding the implementation of a four-day week for employers is multifaceted, with both significant advantages and notable disadvantages. On one hand, the potential for increased productivity, improved employee well-being, higher quality recruitments, cost savings, and environmental benefits presents a compelling case for adopting this model. These factors suggest that a shorter workweek can create a more motivated, healthier, and stable workforce while also contributing positively to operational efficiencies and sustainability goals.
On the other hand, challenges such as reduced customer service availability, compressed workloads leading to increased stress, implementation costs, potential declines in team collaboration, and difficulties in measuring productivity gains cannot be overlooked. These drawbacks highlight the complexities involved in transitioning to a four-day week and underscore the importance of careful planning and consideration by employers.
Ultimately, whether the advantages outweigh the disadvantages will depend on the specific context of each organization, including its industry, workforce dynamics, and operational needs. Employers must weigh these factors thoughtfully to determine if a four-day week aligns with their business objectives and can be implemented without compromising service quality or employee well-being. As legislative changes continue to evolve around flexible working rights, businesses will need to stay informed and adaptable to navigate this evolving landscape effectively.
