Four

For several years, traditional approaches to employment have been put to the test. Societal transformations, employee expectations, and experiments carried out in several countries have reignited an old debate.

How can the organization of work improve Quality of Life and Working Conditions (QVCT) without sacrificing performance?

For human resources professionals, the question is no longer just theoretical. Remote work, flexibility, and the 4-day workweek have become strategic levers, but their real impacts on mental health, productivity, employee engagement, and equity are sometimes poorly understood.

In this article, I propose an in-depth analysis to understand what these initiatives bring and what they require in terms of QVCT.

Definitions Operational

To start, it is important to provide clear definitions, as vocabulary can be misleading.

Telework

Telework refers to any form of work outside the company’s premises. It can be occasional, regular, or hybrid. According to INSEE, by early 2024, nearly 30% of employees in France practice regular telework, compared to less than 5% before 2020.

Flexibility

Flexibility is the ability of employees to adjust their working hours or locations to meet personal or professional needs, within an agreed framework with the employer. This concept focuses on results rather than presence.

4-Day Week or 4-Day Structure

The “4-day week” model involves an actual reduction in the weekly working hours, for example, from 35 to 32 hours, without a salary reduction. The goal is to improve well-being and reduce fatigue.

In the case of the “4-day structure,” the weekly duration remains the same but is condensed into four days instead of five (e.g., 35 hours spread over four days). This model often aims to improve work-life balance by freeing up an additional day but without reducing the total workload.

This distinction is important as the impacts on QVCT vary significantly depending on whether it is a true reduction in working hours or just a compression of hours.

State of Play in Corporate Practices

Telework

INSEE estimates that in 2024, about 30% of employees in France are teleworking regularly (at least one day a week). In the European Union, this figure varies but hovers around 25-35% for eligible positions.

This mode of work has stabilized after the peaks of the COVID-19 pandemic but remains well-anchored in practices.

Flexibility

According to a Slack study conducted by OpinionWay, 46% of employees are considering changing jobs due to a lack of flexibility in their current company. Adopting hybrid organizations helps meet the needs of employees.

4-Day Week

Experiments carried out by 4 Day Week Global in several countries indicate that among companies that have reduced hours without salary reduction, a majority observe an improvement in well-being and work-life balance in over 70% of cases, without significant loss of productivity.

International Experiments

Island: A large experiment with over 2,000 employees has shown that productivity has been maintained or improved in most cases, with a significant reduction in stress. Spain: Regional pilots indicate an improvement in the well-being of employees in 80% of the tested companies.

These results suggest real potential, but they are often conditioned by strong organizational preparation.

Positive Impacts on QVCT

Mental Health and Work-Life Balance

The balance between personal and professional life is one of the main determinants of well-being at work, especially by reducing the fatigue associated with commuting.

In comparison, compressed hours (4-day structure) can generate a sense of urgency and overload if not well supported.

Employees may feel significant pressure over four days to accomplish the same workload. This compression, if not well structured, can lead to increased stress.

Productivity and Performance

One of the most frequently cited arguments against reducing working hours is the risk of loss of productivity. However, evaluations of companies that have adopted the 4-day week often show stability or even a slight improvement in productivity.

Experiments by 4 Day Week Global indicate, for example, that in 55% of cases, productivity has increased.

In some cases, the 4-day structure can create cognitive overload as employees feel compelled to complete the same workload in less time, which can reduce concentration and quality.

Engagement, Retention, and Employer Brand

Flexibility and alternative approaches are important factors in engagement. Flexible schedules and telework then appear essential to remaining in a company.

The 4-day week is also perceived as an attractive benefit and increases candidates’ interest in such positions under these conditions.

Limits and Undesired Effects

Risk of Isolation and Loss of Social Connection

The risk of isolation among employees working remotely permanently exists. This risk must be articulated with support practices and moments of collective presence to maintain a sense of belonging.

Risks of Overload and “Over-Connection”

One of the observed undesirable effects is the phenomenon of “over-connection.” In the absence of a clear framework, employees may extend their availability, which undermines the right to disconnect.

Inequalities Across Professions

Inequalities in access to these practices are a thorny issue. Occupations that require physical presence (production, handling, retail, healthcare) cannot benefit from telework or flexible hours.

This can create perceptions of injustice or division if some employees benefit from advantages that others cannot have.

Implementation Conditions That Matter

The impact on QVCT depends less on the device itself than on the quality of its implementation. Several elements emerge from the analysis of successful experiences.

Co-construction and Participative Management

Involving employees and managers from the design stage of the device improves adherence and prevents resistance. Organizations that seek the input of their teams and conduct pilot phases show a better understanding of concrete needs.

Clarity of Objectives and Indicators

Defining precise HR indicators (well-being, engagement, workload, performance) allows for continuous adjustment of practices. For example, measuring the impact on stress, absenteeism, or satisfaction before/after provides reliable benchmarks for successive iterations.

Manager Training

The role of the manager in a flexible environment is crucial. It involves promoting communication through individual and collective rituals, maintaining team cohesion, managing conflicts, and driving performance through objectives rather than presence.

Respect for the Right to Disconnect

Organizations that are best evaluated in this transition are those that establish clear unavailability periods and rules for responding to messages outside of hours to protect mental health. The role and exemplarity of the managerial line are non-negotiable on this issue.

Measuring the Impact on QVCT: Prioritized Indicators

For HR, measuring the real impact of increased flexibility or a shorter week requires both quantitative and qualitative indicators:

– Turnover and Retention: Variations before/after implementation. – Absenteeism and Declared Health: Links with the devices. – Perceived workload: Regular flash surveys. – Objective productivity: Results by job indicators. – Engagement and satisfaction: Survey scores.

Practical Recommendations for HR

To optimize QVCT benefits while limiting adverse effects:

1. Begin with a pilot phase with clear indicators. 2. Co-construct rules with teams to improve acceptance. 3. Train managers in hybrid coordination tools. 4. Integrate regular review phases to adjust devices. 5. Communicate transparently on objectives and measured results.

Conclusion

Telework, flexible hours, and the 4-day week are powerful levers for improving QVCT when implemented with intention and method. Data shows significant positive effects on well-being, engagement, and sometimes performance, but also potential risks if these practices are applied without proper guidance.

A culture based on testing, adaptation, and transparency is necessary to transform these practices into sustainable tools for QVCT.
