Four-Day Week: What Do Belgium's Parties Propose in 2026?

What do Belgium's parties propose on the four-day week in 2026?

In 2026, Belgium's ten main parties do not all mean the same thing when they say "four-day week." Two ideas hide behind the phrase. The first, the compressed week, already exists: it lets you work your current hours over four longer days, without touching pay. The second, the collective reduction of working time, proposes working fewer hours — 32 or 30 — at the same pay. The first is broadly consensual; the second clearly splits the field.

On that second front, the dividing line is clear. The PTB·PVDA, PS, Ecolo and Groen back a reduction of working time with no loss of pay, in the name of quality of life, health at work and employment. The N-VA, MR and Open VLD refuse to cut paid hours, citing labour costs and competitiveness, and bet on flexibility. Vooruit, Les Engagés and the CD&V sit in between, more open to experiments than to a collective norm written into law.

This opposition does not point to a "good" and a "bad" programme. It sets out two answers to the same question: how should working time be organised in an economy where labour costs are high and companies demand flexibility? The first bets on fewer hours to live better and hire more, even if it raises labour costs. The second bets on keeping hours and free choice, even if that leaves shorter time out of reach for many. Both camps talk about working time; they pull on different levers.

Compressed week or genuine working-time reduction: what's the difference?

The distinction is the key to the whole debate. The compressed week keeps the same volume of hours — say 38 a week — but spreads them over four longer days, up to about 9.5 hours, without changing pay. The collective reduction of working time cuts the number of paid full-time hours: 32 or 30 hours for the same pay.

In practice, these two measures do not cost the same and do not aim at the same goal. The compressed week changes nothing about labour costs for the employer: the worker puts in the same hours, only grouped together. That is why it is legal and consensual today. A reduction of working time at maintained pay, by contrast, raises the hourly cost of labour, unless offset by productivity gains or public support. It is that extra cost, and how to finance it, that crystallises the disagreement between parties.

What the legal framework says: the labour deal, adopted by the Chamber on 29 September 2022, made the compressed week available to any full-time employee who requests it. The arrangement is voluntary, agreed for six renewable months, and the employer must reply in writing. Nothing in that text reduces working time: it reorganises the week, it does not shorten it. So when a party says "four-day week," the real question is always: does it mean compressing, or reducing?

How can these positions be read without taking sides?

Each party gets a symbol per lever here: a green + when it clearly backs that approach, an amber ~ for an intermediate or conditional stance, a red − when it opposes it. This system replaces stars or scores out of five, which would suggest a moral ranking.

The key point: no column designates a "good" party. A party marked with a + on cutting hours is often marked with a − on flexibility without reduction, and vice versa. The two levers answer different priorities — living better and sharing work for some, preserving competitiveness and free choice for others — defended by different electorates. Reading the table means spotting the lever each party favours, not handing out a prize for virtue.

What do the parties that want to cut working time propose?

The left-wing parties want to cut the number of hours worked without touching pay. The PTB·PVDA carries the clearest measure: making the 30-hour week the new full-time norm, with no loss of pay. What the programme says: start with the public sector and physically demanding jobs, offset with new hiring, and draw on experiments abroad — Sweden, the United Kingdom, Iceland, Spain. The stated aim is to free up time, fight burnout and create jobs.

The PS defends a more moderate reduction. In February 2024, its leader Paul Magnette proposed a 32-hour week with no loss of pay, framed as a collective target to be negotiated sector by sector rather than an immediate switch. Ecolo and Groen support the principle of a working-time reduction, often tied to work-sharing, health and the ecological transition, without always fixing a single figure. The details vary, but the logic is shared: fewer hours, same pay, more jobs.

The underlying argument is twofold: quality of life and employment. Its supporters argue that, with high productivity, part of the gains can be taken as free time, and that a shorter week reduces exhaustion and redistributes work. The criticism, voiced by the right and employer organisations such as the FEB, is that cutting hours at equal pay raises labour costs, penalises firms exposed to competition, and is affordable neither for every SME nor for the state. The debate is less about the value of free time than about who pays the bill.

What do the parties that refuse to cut hours propose?

The centre-right and right-wing parties refuse to cut paid hours and prefer to reorganise work. The N-VA, MR and Open VLD share the same line: the compressed week and individual choice, yes; the collective 32- or 30-hour norm, no. Their reasoning starts from labour costs, already high in Belgium: cutting hours at maintained pay, they say, amounts to raising the hourly cost and weakening the competitiveness of firms as well as public finances.

This camp favours flexibility over reduction. Rather than shorten the week for everyone, it wants to give firms and workers the tools to organise time differently: voluntary compressed week, variable schedules, annualisation. The De Wever government's agreement (Arizona, 2025-2029) illustrates this orientation. The labour-law modernisation that took effect on 1 June 2026 relies on more flexibility, including the annualisation of working time, rather than on cutting the legal duration.

The underlying argument is economic sustainability: in an open economy, a rise in labour costs not offset by productivity threatens the very jobs it claims to create. The criticism, voiced by the left and the unions, is that flexibility shifts the balance in the employer's favour, that annualisation can lengthen busy weeks without enough compensation, and that free choice stays theoretical when bargaining power tilts toward the company. Here too, the same word — flexibility — is a promise for some and a threat for others.

Where do Vooruit, Les Engagés and the CD&V stand?

These three parties occupy the middle ground and blur the left-right divide, because they sit in the Arizona coalition while coming from different families. Vooruit, the Flemish socialists, is traditionally open to the working-time debate but, in government, takes a more cautious line than the PS or PTB·PVDA. Hence its double ~: sympathy in principle for a better work-life balance, without carrying the 32-hour norm as an immediate goal.

Les Engagés and the CD&V, for their part, stress the balance between work and family life and tailored solutions rather than a general reduction. They support the compressed week, time-credit schemes and flexibility for parents and carers, but refuse to write a shorter week into law for everyone. Hence the ~ on reduction and the + on reorganisation: neither the collective shortening advocated on the left, nor a refusal of any change, but a mix presented as pragmatic.

By contrast, the Vlaams Belang is hard to place on this axis, hence its double ~. The party defends the purchasing power and well-being of Flemish workers, but remains in federal opposition and has not made working-time reduction a signature theme, its central cleavage being more about identity and immigration than the organisation of work. Its stance owes less to the reduction / flexibility pair than to a priority given to other issues.

Is the four-day week a success in Belgium?

No: despite a legal framework open since 2022, the compressed week remains marginal. According to Acerta, with May 2025 data, about 0.8% of Belgian workers use this arrangement and fewer than 3% of companies offer it. The scheme is growing, but from a very low base, to the point that the press has called it a "flop."

Several reasons explain this low take-up. First, most employees prefer shorter days spread over five days rather than 9.5-hour days over four. Next, the scheme requires an administrative effort: the arrangement lasts only six months, each request must receive a written reply, and the organisation has to lend itself to it. Finally, since it is voluntary and changes neither hours nor pay, it does not deliver the gain many wrongly associate with a "real" four-day week.

This record sheds light on the political debate. For the right, weak take-up shows that no model should be imposed and that choice should be left open, and that the social demand for shorter hours is overstated. For the left, it shows the opposite — that the compressed week is not the right answer, since it does not lighten the load — and that a real cut in hours is needed to change things. The same figure, 0.8%, feeds two opposing readings.

To dig deeper, the comparator lets you place two parties side by side on employment, the ranking sums up positions theme by theme, and the quiz starts from your priorities rather than from a programme. The methodology explains how these positions are collected and remains open to challenge.

What this comparison does not settle

This table does not say which approach "works" best: the real effect of a working-time reduction or of greater flexibility depends on a sector's productivity, company size, the financing chosen and the balance of social power — all parameters that outrun a single term of government. Nor does it factor in your own situation — job, schedule, family load, status — which often weighs more than a national average.

The right reflex, then, is not to pick a winning camp, but to link each position to the lever it pulls, and then to weigh this overview against what you expect, personally, from the organisation of working time.
