When an ADHD employee is underperforming at work, it’s often due to unseen challenges, not a lack of effort or capability. Neurodivergent professionals bring strengths like innovation, resilience, and out-of-the-box thinking. However, without the right support, these strengths may not be fully realized. By learning how to manage someone with ADHD effectively, you can turn underperformance into progress and productivity.

This guide explores practical, legal, and empathetic strategies for supporting an ADHD employee underperforming in their role. Whether you’re managing staff with ADHD, supervising neurodivergent teams, or are a manager with ADHD yourself, these insights will help create a more inclusive, supportive workplace.

Why Supporting ADHD Employees Matters

  • 1 in 20 adults lives with ADHD, often undiagnosed in the workplace.
  • ADHD is a protected characteristic under the UK’s Equality Act 2010, requiring reasonable adjustments.
  • Helping an ADHD employee underperforming can unlock productivity, creativity, and loyalty.

Recognising Signs of an ADHD Employee Underperforming

Knowing how to supervise someone with ADHD starts by recognising common signs of struggle. These may include:

  • Missing deadlines due to time blindness or distraction
  • Disorganised workspaces and difficulty locating files or documents
  • Procrastination, task avoidance, or inconsistent output
  • Interruptions during meetings or impulsive decisions
  • Struggles with routine tasks or sustaining focus on long-term projects

These behaviours often result from ADHD symptoms rather than a lack of motivation. Being proactive in managing ADHD employees helps reduce misunderstandings and burnout.

Set Clear Expectations and ADHD-Friendly Goals

One of the best strategies for managing employees with ADHD is to offer structure and clarity. Supporting an ADHD employee underperforming with clear goals can improve engagement and confidence.

Use SMART Goals:

  • Specific: Define exactly what needs to be done
  • Measurable: Track progress using tools or weekly updates
  • Achievable: Match goals to the employee’s strengths
  • Relevant: Ensure tasks align with broader priorities
  • Time-bound: Set clear deadlines with flexibility for ADHD adjustments at work

Provide task checklists, Kanban boards, or visual timelines to help employees with ADHD organise their work more effectively.

Offer Consistent and Constructive Feedback

Frequent feedback supports an ADHD employee underperforming by offering real-time course correction and reassurance. ADHD support at work should always include:

  • Weekly 1:1 meetings to check in and realign goals
  • Written notes after conversations to confirm expectations
  • Celebrating progress to reinforce motivation
  • Actionable suggestions over generalised criticism

Managing an employee with ADHD means reframing feedback as collaboration rather than correction.

Design ADHD-Friendly Work Environments

Small environmental changes can support an ADHD employee underperforming. Here are common workplace adjustments for ADHD:

  • Noise-cancelling headphones or quiet zones for deep focus
  • Clutter-free, distraction-limited desks
  • Structured routines with digital calendars and alarms
  • Flexible hours or remote work options where possible

Workplace adjustments for ADHD don’t require an overhaul—they’re often inexpensive changes that yield major benefits.

Help ADHD Employees Manage Time More Effectively

Time management is a frequent challenge. If you’re managing someone with ADHD who struggles to meet deadlines, try these approaches:

  • Time Blocking: Reserve specific hours for tasks in calendars
  • Pomodoro Technique: Focus for 25 minutes, then take 5-minute breaks
  • Task Batching: Group similar tasks to reduce mental switching
  • Use of Reminders: Alerts and alarms to help transition between tasks

Encourage employees to experiment with what works best for them and revisit time strategies during check-ins.

Encourage Open Communication and Trust

An ADHD employee underperforming may feel anxious about disclosing their struggles. Build psychological safety with:

  • An open-door policy or scheduled informal chats
  • Regular, supportive check-ins to discuss workload
  • Confidential or anonymous feedback opportunities
  • Training on managing people with ADHD and neurodivergent communication

If you’re a manager with ADHD yourself, share your tools and insights—your experience can build empathy and trust.

Support Development and Mentorship

Professional development is essential to re-engaging an ADHD employee underperforming. Consider these options:

  • Offer training focused on productivity, planning, or focus
  • Provide access to coaching or mental health services
  • Set up peer mentorship for accountability and encouragement
  • Use ADHD-friendly apps for planning and task tracking

Being proactive helps employees with ADHD build confidence and key workplace skills over time.

Legal Considerations: Is ADHD a Protected Characteristic?

Yes—under the Equality Act 2010, ADHD may be considered a disability. Employers are required to make reasonable adjustments to avoid discrimination.

Firing an employee with ADHD without exploring adjustments may result in a legal breach. Always consult HR or legal advisors and consider involving occupational health ADHD assessments to help tailor support.

Common ADHD work adjustments include task structuring, flexible hours, workspace modifications, and extra preparation time before meetings.
