How to talk to a boss about ADHD and underperformance?
Talking to your boss about ADHD can feel daunting, especially if you are worried about being judged or misunderstood. But according to NHS and ACAS guidance, being open about how ADHD affects your work can help you access the right support and reasonable adjustments. This can improve both your performance and wellbeing.
Understanding why performance issues happen
ADHD is not a lack of effort. It is a neurodevelopmental condition that affects executive functions such as focus, time management, organisation, and emotional regulation. According to NICE guidance (NG87), these challenges can affect productivity, communication, and task completion, but they do not define your capability. Many adults with ADHD thrive once tasks are structured and expectations are clear.
If you have noticed issues such as missed deadlines or difficulty staying organised, preparing examples can help your boss understand what is happening. This is not an excuse, but a way to create practical solutions together.
How to start the conversation
Experts at ACAS recommend focusing on what you need rather than on your diagnosis. You might say:
“I have been diagnosed with ADHD, which means I sometimes find it harder to manage distractions or deadlines. I’d like to discuss some ways I can work more effectively.”
It helps to:
- Choose a calm, private time to talk
- Prepare examples of what helps you stay focused, such as quieter workspaces or written follow-ups
- Bring any professional recommendations you have received, such as occupational health notes or clinician reports
Under the Equality Act 2010, ADHD is recognised as a disability. Employers therefore have a legal duty to consider reasonable adjustments. These may include flexible working, written task reminders, or adjusted deadlines, in line with NHS and ACAS workplace guidance.
Support beyond the workplace
If you are still struggling, post-diagnostic coaching or therapy can make a real difference. Evidence from recent studies (2023–2025) shows that CBT-based coaching helps adults with ADHD manage stress and improve executive function.
Services such as Theara Change focus on behavioural coaching and psychological tools to support people with ADHD in professional settings. These approaches complement NHS care but do not replace it.
Takeaway
Talking to your boss about ADHD is not about disclosing a flaw. It is about building the conditions you need to succeed. According to the NHS ADHD Taskforce and NICE, clear communication and tailored adjustments can transform work performance. A supportive conversation is often the first step toward that improvement.
