Is Your Office Making People Sick?

A colleague delivers brilliant work from home all week. Sharp, responsive, creative. They walk into the office on Monday and by 11am they are pale, distracted, and counting the hours. Their manager notices. The assumption writes itself: they are avoiding something. They prefer home because it is comfortable, easy, unaccountable.

But what if the opposite is true? What if home works because it meets conditions the office has quietly abandoned? What if the office is the variable, not the person?

I sit on both sides of the table. On one, the physical design of spaces, specification, acoustics, lighting, materials. On the other, neurodiversity, masking, and the hidden cost of environments that demand conformity. What I notice is that neither lens tells the full story on its own. I can see exactly where a space is helping a person thrive, and exactly where it is draining them before they open their laptop. And right now, what I see is that a lot of offices are failing people in ways leadership does not recognise, because leadership is measuring the wrong things.

Missing the Signal

Managers track attendance and visibility. They assume if someone is physically present, they are productive. If someone performs better at home, the reasoning goes, the problem must be motivation, commitment, or discipline. Nobody stops to ask whether the building itself is the barrier.

There was talk when the five-day statutory sick pay entitlement arrived in Ireland in January 2024 that it would drive a spike in absence. Perhaps it did. But what looks like a policy failure might actually be the first time employees felt permission to name what was happening. When you give people the tools to protect themselves, they use them. Whether that tool is called "sick pay" or "mental health day" matters less than what it reveals: people were already running on empty.

Home works for a simple reason. The human nervous system has control. The lighting is yours. The sound is yours. The temperature, the chair, the air, the pace of the morning. You decide when to speak and when to be silent. You decide whether the door is open or closed. The body settles because the environment is predictable.

Offices Built for Visibility, Not Biology.

The office strips all of that away. Open-plan noise that the brain cannot filter. Harsh, bright lighting that hums at a frequency some people physically feel. Airless rooms. The unspoken rule that presence equals commitment. Every one of these is a signal the nervous system reads as low-grade threat, before a single task has been attempted.

This is not laziness. It is not preference. It is the body responding exactly as it was designed to respond to an environment it cannot predict or control. When the nervous system detects threat, it diverts energy away from the prefrontal cortex, the part of the brain responsible for focus, creativity, and strategic thinking, and channels it into survival. The body braces. Cortisol rises. The person is physically present but cognitively absent, running a defence programme they cannot switch off.

Employers call this presenteeism. They measure it as underperformance. They add it to a performance review and ask the person to improve. What it actually is, is the cost of asking a human to work in an environment their body reads as hostile.

The Canary Effect

Here is what managers miss. The people who struggle most in the office are often the most insightful, the most creative, the most attuned to what is happening beneath the surface. Their sensitivity is not a weakness. It is a diagnostic tool. They are the canaries in the mine, and the mine is the office.

When they flourish at home and collapse at the desk, they are not malingering. They are telling you something precise. The home environment meets the conditions their nervous system needs to function. The office does not.

Compliance Won't Fix a Design Failure

The mistake is thinking the solution is to force them back to the office. Mandates, attendance policies, hybrid rules dressed up as flexibility. These are compliance mechanisms, not design solutions. They address the symptom, the empty desk, while leaving the cause untouched. You can threaten people into the building. You cannot threaten their nervous system into feeling safe once they arrive.

Some employers reports they are managing absenteeism "every day." That is not a policy problem. That is a design problem wearing policy as a mask. When every workplace is reporting the same trend, the common denominator isn't sick pay. It's the building.

Import Home Into the Office. Don't Replicate Home

The solution is to listen to what home is doing right and bring those principles into the shared space. This is not about replicating home in the office. It is about understanding what home provides that the office has stripped away: sensory control, predictability, autonomy over the body's rhythm, and the freedom to regulate before performing.

I know this because I see both worlds. I know what materials, lighting, acoustics, and spatial planning do to the human body. I know which decisions look good on a mood board and feel terrible to work in. I also work with organisations on (neuro)diversity, masking, and the hidden cost of environments that demand conformity. I see what happens when those two worlds collide, when a beautifully designed office still makes people ill because nobody considered the nervous system that has to inhabit it.

The gap between those two perspectives is where the real work lives. It is not enough to design a beautiful office. It is not enough to run a neurodiversity programme. The magic happens when you bring them together, when the physical space and the cultural environment are designed as one system that works with human variation rather than against it.

What Would Make Them Want to Come?

When you design for the nervous system, you do not need to mandate attendance. People choose to be in spaces that feel safe. They gravitate toward environments where their energy goes into contribution instead of survival. The office does not need to be a lifeboat. It needs to be a place the body recognises as safe.

Because the question was never "how do we get people back to the office?" The question is "what would make them want to come?"

I help organisations understand the hidden architecture of their environments, physical, cultural, and sensory. If your team works beautifully from home but falls apart in the office, the building is telling you something. Let's talk about what it is saying. 💜
