As awareness of Attention Deficit Hyperactivity Disorder (ADHD) and other forms of neurodiversity continues to grow, employers are seeing an increase in employees seeking support and adjustments in the workplace.
For a small employer, the difficulty is often knowing what you actually have to do.
Does ADHD automatically mean an employee is disabled? Do you have to agree to every adjustment they request? What happens if their ADHD is affecting performance, attendance or timekeeping?
The starting point is the Equality Act 2010.
ADHD is not automatically treated as a disability in every case.
However, it can amount to a disability under the Equality Act 2010 where it has a substantial and long-term adverse effect on the person's ability to carry out normal day-to-day activities.
"Substantial" essentially means more than minor or trivial, and "long-term" will normally mean that the effect has lasted, or is likely to last, for at least 12 months.
ACAS specifically identifies ADHD as a form of neurodivergence and says that being neurodivergent will often amount to a disability under the Equality Act. Importantly, an employee does not necessarily need to have received a formal diagnosis before they can meet the legal definition of disability.
Employers should therefore avoid taking the approach:
"We don't have to do anything until you provide an ADHD diagnosis."
That can be legally risky.
The question is not simply whether the employee has a medical label. The question is how their condition affects them.
Under the Equality Act 2010, employers have a duty to make reasonable adjustments where a disabled person would otherwise be placed at a substantial disadvantage.
The duty can arise where the employer knows, or could reasonably be expected to know, that the employee is disabled and is experiencing a disadvantage because of that disability.
This means an employer cannot always rely on an employee failing to use the words "reasonable adjustment".
For example, imagine an employee repeatedly tells their manager that they are struggling to concentrate in the open-plan office because of their ADHD. They are making mistakes and regularly staying late to finish their work.
A sensible employer should explore whether reasonable adjustments could support the employee before moving straight to performance management. Where an employee with ADHD is placed at a substantial disadvantage, failing to consider appropriate adjustments could expose the employer to a potential Employment Tribunal claim.
ADHD affects people differently.
One employee may struggle considerably with concentration but be excellent at dealing with customers. Another may find organisation difficult but perform extremely well when dealing with urgent projects.
Workplace difficulties can include:
Employers should therefore avoid having a standard list of "ADHD adjustments" that is applied to everyone.
Adjustments should be based on the particular employee, their role and the difficulties they are actually experiencing.
There is no requirement to agree to every adjustment an employee requests.
The duty is to make adjustments that are reasonable in the circumstances. When assessing reasonableness, a tribunal may consider factors such as the cost of the adjustment, the employer’s size and financial resources, and the availability of external funding or assistance. An adjustment that would place a disproportionate burden on the employer may not be considered reasonable.
For an employee with ADHD, the following may be worth considering.
1. Providing written instructions
Some employees with ADHD may find it difficult to retain lengthy verbal instructions.
Managers could follow conversations with a short email confirming:
This does not mean documenting every conversation. It might simply mean providing greater clarity for important tasks.
2. Breaking large projects into smaller deadlines
Telling somebody that a project must be completed "by the end of the month" may be harder to manage than setting several smaller milestones.
For example:
Instead of:
Complete the report by 30 September.
Consider:
Research completed by 10 September.
First draft by 18 September.
Manager review on 22 September.
Final version by 30 September.
This can provide structure without changing the employee's underlying responsibility for completing the work.
3. Reducing unnecessary distractions
Where the employee works in a noisy office, adjustments could include:
Whether homeworking is reasonable will depend on the job and the business.
An employer does not automatically have to agree to permanent homeworking simply because an employee has ADHD.
4. Flexible start and finish times
Some employees may ask for a slightly different working pattern.
For example, an employee might find that starting at 8am rather than 9am allows them to complete concentration-heavy work before the office becomes busy.
The employer should consider the request against the requirements of the role.
A flexible start may be straightforward for an administrator. It may be considerably more difficult for somebody whose job requires them to open a shop at 9am.
That difference matters when assessing whether an adjustment is reasonable.
5. Regular short management meetings
Instead of relying on occasional lengthy performance meetings, some employees may benefit from short and structured catch-ups.
For example, a manager might spend 10 or 15 minutes each week reviewing:
The purpose is not to micromanage the employee. It is to provide structure where that helps remove a disability-related disadvantage.
6. Providing clear priorities
One common difficulty can arise where an employee receives requests from several people and struggles to determine what should be done first.
Managers can help by being clearer about priorities.
For example:
Small changes to management communication can sometimes be more effective than expensive equipment.
7. Using reminders and task-management tools
Digital tools can help employees organise tasks and deadlines.
Depending on the role, this could include:
Employers should discuss what actually works for the employee rather than imposing additional systems that create more administration.
8. Adjusting meetings
Long meetings can be difficult for some people with ADHD.
Possible adjustments might include:
Again, the adjustment should relate to the actual difficulty being experienced.
9. Allowing short concentration breaks
For some roles, allowing an employee to take brief breaks before returning to a concentration-heavy task may help them work more effectively.
This does not necessarily mean giving substantially more break time than other staff.
It might involve allowing greater flexibility over when normal breaks are taken.
10. Reviewing workload organisation
Occasionally the way a job is organised may create unnecessary difficulties.
For example, an employee may be expected to alternate constantly between administrative work, telephone calls and customer queries.
Where operationally possible, grouping similar tasks together might help.
An employer does not normally have to remove essential duties from a role. ACAS makes clear that an employer does not have to change the basic nature of the job when considering reasonable adjustments.
No.
Employees can suggest adjustments, and employers should listen carefully to those suggestions, but the employee does not have an automatic right to dictate the adjustment.
There may be several ways of addressing the same disadvantage.
For example, an employee might request permanent homeworking because they find the office distracting.
The employer might reasonably conclude that permanent homeworking is not workable because the employee needs to supervise staff on site.
Alternative adjustments could include:
What is reasonable depends on the circumstances.
Relevant considerations can include whether the adjustment will actually reduce the disadvantage, how practical it is, the cost and the effect on the business.
A multinational organisation and a business employing six people may therefore reach different reasonable conclusions about the same adjustment.
ADHD does not prevent an employer from managing performance.
Employees with disabilities can still be expected to perform their jobs.
The mistake employers sometimes make is starting disciplinary or capability action without first considering whether the performance problem is connected with a disability.
Suppose an employee repeatedly misses administrative deadlines and tells their manager that their ADHD makes organising multiple deadlines difficult.
Before issuing warnings, the employer should consider whether reasonable adjustments could help.
That might include:
After reasonable adjustments have been made and given an appropriate opportunity to work, the employer can still assess whether the employee is meeting the required standard.
Reasonable adjustments are intended to remove disadvantages. They are not a requirement to ignore poor performance indefinitely.
A key consideration for employers should be: if an employee is experiencing difficulties in the workplace, what can reasonably and practically be done to reduce those difficulties and enable them to perform effectively?
The focus should be on equity rather than simply equality:
This approach can be valuable regardless of whether an employee meets the legal definition of disability. Recognising individual needs and adopting appropriate workplace practices can help create a more supportive and effective workforce. From an operational perspective, this may also contribute to improved employee retention, job satisfaction, engagement and productivity.
This can be more difficult.
An employee might say that ADHD causes difficulties with time management and that their repeated lateness is disability-related.
The employer should investigate rather than immediately treating the matter as straightforward misconduct.
Possible adjustments might include a slightly later start time, provided the role allows it.
However, changing hours will not always be reasonable.
If somebody's job is to open a premises at 8.30am, allowing them to arrive whenever they wish is unlikely to solve the practical problem for the business.
The employer should consider whether there is another workable adjustment before deciding what action to take.
Sometimes.
An occupational health assessment can be useful where:
An occupational health adviser might recommend adjustments, but those recommendations are not automatically binding.
The employer still decides what adjustments are reasonable while taking account of its legal obligations.
Employers should also remember that medical information must be handled confidentially and access should normally be limited to people who genuinely need it.
Do not simply refuse to discuss adjustments.
ACAS expressly states that a neurodivergent worker does not need a diagnosis to be considered disabled under the Equality Act 2010.
An employee may be waiting months for an ADHD assessment.
If they explain that they are experiencing difficulties that appear capable of being addressed through relatively simple changes, there is often little benefit in insisting on formal medical evidence before doing anything.
Where the situation is unclear, the employer can discuss the difficulties with the employee and consider seeking occupational health advice.
Employers should not attempt to diagnose ADHD themselves.
Once adjustments have been agreed, record them.
A short reasonable adjustments plan can cover:
Adjustments do not always have to remain unchanged forever.
Something that works today may no longer be necessary in six months. Equally, an adjustment that initially appears sensible may prove ineffective.
Set a review date.
For example:
"We will trial the employee working from home on Wednesdays for eight weeks and review whether this has improved their ability to complete concentration-heavy tasks."
That is much easier to manage than agreeing vaguely that the employee can "work from home when needed".
Employees with ADHD may also qualify for support through the government's Access to Work scheme.
The scheme can provide practical support to people with disabilities or health conditions and expressly includes ADHD within its eligibility guidance. Support can include specialist equipment, assistive software and job coaching.
There is an important distinction, however.
Access to Work does not replace the employer's legal responsibility to make reasonable adjustments. Government guidance states that the scheme is intended to provide support above and beyond adjustments the employer is legally required to make.
When an employee tells you they have ADHD or asks for adjustments, avoid making an immediate decision during the first conversation.
Instead:
1. Ask the employee what difficulties they are experiencing at work.
2. Ask what adjustments they believe might help.
3. Consider which parts of the role are genuinely essential.
4. Consider whether the suggested adjustment is practical.
5. Explore alternatives if the employee's preferred adjustment is not workable.
6. Obtain occupational health advice where necessary.
7. Confirm agreed adjustments in writing.
8. Set a date to review whether they are working.
Most importantly, focus on the workplace difficulty rather than debating whether ADHD should affect somebody in that particular way.
Different people can experience the same condition very differently.
ADHD does not mean that employers must lower every performance standard or agree to every request an employee makes.
But employers should take requests seriously.
If an employee may be disabled under the Equality Act 2010, simply saying "everyone has to be treated the same" can create a problem. The reasonable adjustments duty exists precisely because treating everyone identically can sometimes place a disabled employee at a disadvantage.
In many ADHD cases, the adjustments being requested are relatively modest: clearer instructions, quieter working arrangements, structured deadlines or more regular management contact.
The safest approach is to understand the difficulty, consider practical adjustments, document what has been agreed and review whether it is working.
That puts the employer in a much stronger position if performance or attendance problems remain later.
