The Hidden Cost of Masking ADHD at Work

Many adults with ADHD in the workplace do not look like they are struggling. They appear competent, capable, and in control. But what cannot be seen from the outside is the extraordinary effort required to maintain that appearance.

Many adults with ADHD in the workplace do not look like they are struggling. They appear competent, capable, and in control. They meet their deadlines, eventually. They perform well in high-stakes situations. They manage their teams, complete their projects, and show up every day.

But what cannot be seen from the outside is the extraordinary effort required to maintain that appearance. Behind the competent exterior of many undiagnosed or unsupported adults with ADHD sits chronic exhaustion, persistent anxiety, and a deep, often unconscious cost to their health, identity, and sense of self. This phenomenon is called masking, and understanding it is essential for HR professionals and managers who want to support neurodivergent employees effectively, identify burnout risk before it becomes crisis, and build workplaces where people do not have to perform a version of themselves that is slowly destroying their wellbeing.

What Is ADHD Masking?

Masking, also referred to as camouflaging, is the act of suppressing, hiding, or compensating for natural neurodivergent behaviours in order to appear socially acceptable, professionally competent, or simply 'normal' in a neurotypical environment.

For someone with ADHD, masking can take many different forms depending on the individual, their environment, and how long they have been doing it. Common masking behaviours include:

Over-preparing for meetings, presentations, and conversations to compensate for difficulties with spontaneous verbal processing and working memory
Working late into the evening to complete tasks that took twice as long as they should have, due to difficulties with task initiation and sustained attention during the working day
Rehearsing conversations mentally before they happen, anticipating misunderstandings or moments where ADHD symptoms might become visible
Suppressing emotional reactions, particularly the intense, rapid emotional responses associated with Rejection Sensitivity Dysphoria, in order to appear professional
Forcing stillness, eye contact, or attentiveness in meetings that feel neurologically overwhelming
Avoiding disclosure entirely, out of fear of stigma, professional consequences, or simply not having the language to explain what they experience

Masking is not a choice in any straightforward sense. It is most often a deeply learned behaviour, developed over years, frequently beginning in childhood, as a response to environments that communicate, explicitly or implicitly, that the natural way the ADHD brain operates is unacceptable.

Why Masking Often Goes Unrecognised, Particularly in Women

ADHD has historically been diagnosed and researched primarily in boys and men, where it more frequently presents with visible, externalised symptoms: physical hyperactivity, impulsive outbursts, and overt inattention. In girls and women, ADHD more commonly presents with internalised symptoms: mental restlessness, anxiety, emotional sensitivity, and chronic self-criticism.

This means that girls with ADHD have, for generations, been more likely to develop sophisticated masking strategies early in life, and to reach adulthood without a diagnosis or any external framework for understanding their experience. Instead, the narrative that develops is often one of personal failure: not trying hard enough, being too emotional, being disorganised or scatterbrained.

The cumulative effect of decades of masking, without recognition, without support, and often without even knowing that ADHD is the underlying cause, is significant. Many women receive their first ADHD diagnosis in their thirties, forties, or later, often triggered by a life event that exhausts their remaining capacity to compensate.

Masking is not a neutral coping strategy. It carries a profound and well-documented cost, one that accumulates gradually and often becomes visible only when it reaches a crisis point.

Burnout

ADHD burnout is distinct from general workplace burnout, though the two can co-occur. It results from the sustained effort of managing ADHD symptoms, maintaining the performance of neurotypical behaviour, and navigating an environment that is not designed for how the ADHD brain works. ADHD burnout can involve complete cognitive and emotional exhaustion, an inability to perform tasks that were previously manageable, and a collapse of the compensatory systems the individual has spent years building.

From a manager's perspective, ADHD burnout can appear sudden and inexplicable, a previously high-performing employee who seems to fall apart rapidly. In reality, the burnout has typically been building for months or years. The visible collapse is the final stage of a long, invisible process.

Anxiety and Depression

Chronic masking creates a state of sustained hypervigilance, a continuous, low-level monitoring of one's own behaviour, speech, and performance. Questions such as 'Am I talking too much?', 'Did I miss something important?', 'Have I seemed distracted?' run as a near-constant background process. This cognitive load is exhausting, and over time it reliably produces anxiety.

Depression frequently follows, particularly when individuals have spent years believing that their difficulties reflect personal inadequacy rather than a neurological difference. The shift from self-blame to accurate understanding of ADHD can be genuinely transformative, but without it, the psychological cost compounds year on year.

Identity Confusion and Loss of Self-Trust

When masking becomes habitual, the line between the performed self and the authentic self can become difficult to locate. Individuals who have spent years suppressing their natural ways of thinking, communicating, and engaging with the world often report profound uncertainty about who they actually are, separate from the performance they have been maintaining.

Research indicates that adults with undiagnosed or unsupported ADHD are significantly more likely to experience anxiety, depression, and burnout than those who have received appropriate diagnosis and support. The mental health cost of masking is not incidental. It is one of the most serious consequences of inadequate workplace inclusion.

Why Masking Is a Specific Problem for Employers

From an organisational perspective, ADHD masking creates a deceptive picture that puts both the employee and the employer at risk.

When masking is effective, managers see adequate performance and do not see the strain behind it. This means:

Support is not proactively offered, because there is no visible signal that it is needed
Adjustment conversations do not happen, because the employee appears to be coping
Early signs of overload, deteriorating wellbeing, and increasing exhaustion are missed or misread as engagement or attitude issues
When the inevitable crash occurs, burnout, anxiety crisis, or abrupt resignation, it appears sudden and is difficult for managers to contextualise

The organisational consequences are significant. High-performing, experienced employees leaving unexpectedly or going on long-term sickness absence is costly in financial terms, in team disruption, and in the loss of institutional knowledge. In some cases, inadequately managed ADHD difficulties lead to formal grievance or employment tribunal processes, which carry both financial and reputational risk.

What Reduces Masking: Building a Workplace Where It Is Safe Not to Hide

Reducing masking is not primarily about encouraging disclosure, though disclosure becomes more possible in the right environment. It is about building workplaces where neurodivergent employees do not need to mask in the first place. That requires deliberate, structural change at an organisational level.

Psychological Safety as a Foundation

Psychological safety, the genuine belief that one will not be penalised, judged, or treated differently for speaking honestly about one's needs, is the foundational requirement. Without it, all other inclusion measures are undermined. HR teams and senior leaders play a critical role in modelling the norms that create it.

Practical Environmental Changes

Many of the adjustments that reduce the masking burden for employees with ADHD are straightforward, low-cost, and benefit the wider workforce:

Providing agendas in advance of meetings, so employees can prepare and feel less reliant on in-the-moment verbal processing
Following up verbal discussions with written summaries, reducing the risk of important information being lost from working memory
Offering clarity on priorities and expectations, rather than assuming employees can infer what matters most
Providing designated focus time, protected blocks in the calendar where meetings and interruptions are minimised
Normalising the use of assistive tools such as noise-cancelling headphones, task management software, and digital timers without requiring employees to justify their use

Normalising Different Working Styles

When organisations communicate, through policy, through leadership behaviour, and through everyday management practice, that different ways of working are not only tolerated but genuinely valued, the psychological burden of masking reduces. This does not require announcing that neurodivergent employees are present. It requires consistently modelling that working styles, communication preferences, and focus patterns can legitimately vary.

Disclosure should never be required or pressured. But a psychologically safe environment makes it possible for those who want to disclose to do so without fear, and that possibility alone reduces the chronic anxiety associated with concealment.

For Individuals: Recognising Your Own Masking

If you are reading this and recognising your own experience in the description of masking, that recognition itself is significant. Understanding that what you have been doing is masking, rather than simply failing to be the person you should be, can be the beginning of a different relationship with yourself and with the environments you navigate.

Some practical first steps:

Begin to notice the specific situations, interactions, and demands that require the most effort to manage. These are often the areas where your masking is most active and most costly.
Seek support from a GP, psychiatrist, or psychologist if you suspect undiagnosed ADHD. Adult ADHD assessment waiting lists are long, but the process of pursuing assessment is itself a form of self-advocacy.
Where it feels safe, consider selective and gradual disclosure to trusted colleagues or a supportive manager. You do not have to explain everything, and you are not obligated to disclose to anyone.
Access ADHD coaching or therapy if available. Both can provide a space to explore the impact of masking and develop strategies that reduce its necessity.

Frequently Asked Questions

How do I know if I am masking my ADHD at work?

Masking often shows up as a chronic sense of exhaustion that is disproportionate to what you have visibly accomplished. You may feel that you are working significantly harder than your colleagues to achieve the same results, or that you are constantly monitoring your own behaviour to avoid being found out. If work feels like a sustained performance rather than a genuine expression of your capabilities, masking is likely a factor.

Is masking always a conscious choice?

Frequently not. Masking behaviours are most often developed gradually over many years, beginning in childhood and adolescence, as automatic responses to social and environmental pressure. Many adults are not aware that they are masking until they encounter the concept, at which point, recognition can be both clarifying and emotionally significant.

What should an HR professional do if they suspect an employee is masking?

Do not attempt to diagnose or confront the individual directly. Instead, focus on creating the structural and cultural conditions that reduce the need for masking: psychological safety, clear communication, flexible working, and visible normalisation of different working styles. If a performance concern has emerged, approach the conversation with curiosity rather than judgement, and create space for the employee to share what they need.

Can masking stop completely?

For most people, masking reduces rather than disappears entirely, particularly in professional environments where social norms remain relatively fixed. However, with appropriate support, diagnosis, and the development of genuinely neuroinclusive environments, the intensity and cost of masking can reduce significantly. The goal is not to eliminate all accommodation of social norms but to remove the unsustainable, health-damaging burden of constant performance.

Questions Leaders Often Ask

How do I know if someone on my team is masking?

Masking is often invisible by design. Signs can include inconsistent performance, sudden burnout, or an employee who appears capable but regularly struggles with tasks that seem straightforward. Creating a safe environment for honest conversations is more effective than trying to spot it.
