Luxembourg Proposes Four 10 Hour Days, but Only Through Collective Agreements

Luxembourg has put a new option for organizing the working week on the table. According to a report by RTL Today on October 28, Labour Minister Marc Spautz has proposed allowing a four day week made up of 10 hour days, but only when it is set out in a collective agreement.

The idea is narrower than a national four day week. It does not change the country's labor law itself. Instead, it gives employers and unions a new tool they can choose to use through negotiation.

What the Proposal Includes

According to RTL Today, the proposal would allow a working week of four 10 hour days where a collective agreement provides for it. It also includes the option of reducing the maximum working week from 44 hours to 35 hours under such agreements.

Other elements reported by RTL Today include allowing two breaks during the working day instead of one, and greater flexibility for part time arrangements. Taken together, the measures are about giving negotiated agreements more room to shape schedules.

The key word throughout is "collective." Individual employers could not simply impose a four day schedule, and individual workers could not demand one, under this approach. It would happen sector by sector or company by company, through bargaining.

A Change in Direction

RTL Today reports that the proposal reverses the position of Spautz's predecessor, Georges Mischo. That shift is significant. A previous stance has given way to a more open one, though still with clear guardrails.

The employers' side, represented by the UEL, was present at the discussions through Charlotte Junck, according to the report. The social partners are now taking the proposal back to their own bodies for consideration, so nothing is final yet. That consultation stage is typical of Luxembourg's social dialogue model, in which government, employers and unions work through major workplace changes together before anything reaches a vote.

Why Collective Agreements Matter

Routing the four day week through collective agreements is a deliberate choice. It means changes are negotiated by the people who know a particular industry best, rather than set by a single rule for every workplace.

For professionals, this approach has trade offs. On one hand, it could allow schedules that genuinely suit the work, such as longer shifts in exchange for an extra day off. On the other, it means access depends on whether your sector or employer is covered by an agreement, and on what that agreement says.

A 10 hour day is also not for everyone. It can suit people who value long weekends or fewer commutes. It can be harder for parents, caregivers and anyone whose energy fades late in the day. The debate in Luxembourg reflects the same tension seen in many workplaces: flexibility for some can mean strain for others.

Lessons for Workplaces Elsewhere

Even outside Luxembourg, the proposal offers a useful model for thinking about schedule changes. Instead of treating the four day week as all or nothing, it treats it as one option among several, negotiated in context.

Leaders considering compressed schedules can borrow that mindset. Start with the work itself. Ask which roles can absorb longer days, how coverage will be handled, and how breaks and wellbeing will be protected. Then involve employees in designing the arrangement, rather than announcing it from the top. Pilot the change with a small team first, measure the results honestly, and be willing to adjust.

What Comes Next

The proposal now goes back to employers and unions for discussion. Whether it becomes reality, and how widely it is adopted, will depend on those talks and on how many collective agreements choose to use the new options.

For now, Luxembourg has shown one way to open the door to a shorter week without forcing anyone through it. Professionals everywhere will be watching how it works in practice.
