You arrive at the office on a Monday morning, and your usual spot is taken. A colleague has settled there because they needed to be near the window. The flex office is based on this principle: no more assigned desks, each employee chooses their space according to their tasks for the day.
The concept, often referred to as On Flex or o-flex depending on the platforms, appeals to companies looking to optimize their square footage. However, this flexibility comes with a human cost that enthusiastic assessments rarely measure.

Flex office and the March 2026 ordinance: what changes for employees
Since the ordinance of March 12, 2026, companies with more than 50 employees can no longer impose a strict flex office without the agreement of employee representatives. This measure reflects a regulatory shift towards what some legal experts call the right to anchoring.
In practical terms, an employer wishing to eliminate assigned desks must engage in formal consultation. In case of non-compliance, sanctions are provided. This framework protects employees who were subjected to the transition to flexible offices without being consulted.

To find information on On Flex and o-flex and understand the different variations of this organizational mode, the topic deserves to be explored beyond just real estate arguments.
This ordinance reflects a ground-level observation: after a significant post-pandemic increase, enthusiasm for the flex office is declining. Recent surveys show a growing disaffection, linked to a feeling of insecurity and loss of territorial identity among employees. The preference is shifting towards hybrid assigned desks, where everyone has a reference desk while still retaining the option to work remotely.
Quiet spaces in flex office: a gender bias rarely measured
Have you ever noticed that in an open space without fixed desks, certain profiles systematically occupy the same areas? Quiet spaces, isolated pods, and concentration rooms are limited resources. In a flex office, access to them is based on the first-come, first-served principle.
This mechanism creates a structural bias. Employees who arrive early, who do not have morning childcare obligations, or who adopt territorial occupation behavior, monopolize these spaces. Several field reports indicate that women have less access to quiet and secure spaces in organizations with flex offices.
Why this imbalance persists
Three factors combine:
- Domestic constraints (school runs, medical appointments) shift arrival times and reduce the window of choice for spaces.
- Informal but tolerated “marking” behaviors favor profiles that frequently move around the office and know the spatial codes of the place.
- The absence of explicit allocation rules turns the availability of quiet spaces into a tacit power struggle, without managerial arbitration.
Proponents of the flex office present flexibility as inherently egalitarian. On paper, everyone has access to everything. In practice, the absence of assigned desks reproduces existing inequalities instead of correcting them. This bias remains poorly documented in company assessments, which measure space occupancy rates but not distribution by profile.
Creativity and informal exchanges: what the flexible office makes disappear
A classic argument in favor of the flex office is the mixing of teams. By changing neighbors every day, it would encourage chance encounters and new ideas. Experiences from tech SMEs tell a different story.
Qualitative studies report a decrease in serendipity in organizations with flex offices. Informal exchanges, those that arise from regular physical proximity, become rarer when no one knows where to sit the next day. Teams report a reduction in innovative ideas stemming from chance proximity.
The paradox is clear: the flex office promises more collaboration, but the constant rotation breaks the micro-rituals that nourish it. A pair of developers who shared a pod for six months built a common vocabulary and mutual proofreading reflexes. In flex, this pair must reform every morning, sometimes on different floors.
When coworking replaces the coffee machine
Some companies compensate by multiplying internal coworking spaces, lounges, and social areas. Management relies on layout to recreate what the organization has eliminated. But a couch does not replace a regular office neighbor. Arranged conviviality remains optional, whereas daily proximity naturally imposed the connection.
Gamified flex office: how Asia circumvents resistance
In Japan and South Korea, companies have adopted a different approach to flexible offices. Their booking applications incorporate a rewards system: employees accumulate points by varying their workspaces, which can be converted into wellness breaks or tangible benefits.
This model of gamified flex office reduces the resistance observed in Europe. Instead of imposing mobility from the top down, it makes it attractive through an incentive mechanism. The adoption rate increases without generating the feeling of dispossession described by French employees.
The comparison is instructive for companies considering transitioning to flex. The issue is not always the concept itself, but how it is deployed. Partial remote work combined with a transparent booking system, with clear rules for accessing quiet spaces, produces less frustration than a strict flex office without support.
The March 2026 ordinance pushes in this direction: consult employees, set rules, support the change. The flex office is not doomed, but its most rigid version, which eliminates all anchoring without compensation, is losing ground. Organizations that succeed in flexible offices are those that establish equitable access rules and measure their effects on all employee profiles, not just on cost per square meter.
