FND Employment: Working With Changing Symptoms

A job can provide income, routine, purpose and connection. It can also become one more place where you feel pressure to prove that you are unwell enough for help, yet well enough to stay. FND employment is not about pushing through until you crash or giving up at the first barrier. It is about finding a safer, more realistic way to work with symptoms that can change from hour to hour.

You are not making this up. Functional Neurological Disorder can affect movement, speech, pain, fatigue, concentration, vision, sensation and seizures or episodes. Some of those symptoms may be invisible to colleagues. Others may be obvious one day and absent the next. That variation is real, and it is often the part employers struggle to understand without clear information.

FND employment starts with what work costs you

Before deciding whether to apply for a role, return after sickness absence or ask for changes, look beyond the question, “Can I do this?” A more useful question is, “What does doing this cost me, and can that cost be managed?” You may be able to complete a shift but need two days in bed afterwards. You may manage focused work in the morning but find brain fog, pain or functional seizures more likely later in the day.

Think about the whole working day: getting washed and dressed, travelling, the physical or mental demands of the role, breaks, noise and lighting, getting home, and what is left for eating, caring responsibilities and recovery. This is not pessimism. It is practical information that helps you make decisions before your body is forced to make them for you.

A brief symptom and activity record can reveal patterns that memory misses. If you experience functional seizures or episodes, a private tracker such as SeizeControl can help you record timing, possible triggers, recovery time and medication context, then turn this into a clearer summary for an appointment. Use the information to understand your needs, not to judge yourself for having them.

You do not have to explain everything at once

Telling an employer about FND is a personal decision. Some people disclose at application stage because they need adjustments for an interview. Others wait until an offer is made or until symptoms affect work. There is no single right moment. The best approach depends on your role, the support you need, how safe the workplace feels and whether there are immediate safety concerns.

You do not need to share your whole medical history to ask for practical support. It can help to describe the functional impact first: “My neurological condition causes fluctuating fatigue and problems with concentration”, or “I can have episodes where I need a quiet, safe space and time to recover.” Then explain what would make work more manageable.

If speaking feels daunting, prepare notes beforehand. Keep the conversation focused on your job and the solution rather than trying to persuade someone that FND is real. A manager who has never heard of FND may need time and clear information. That lack of knowledge should not become your burden to carry alone, but a written summary can reduce misunderstandings.

Ask for adjustments that match the role

In the UK, FND may meet the legal definition of disability under the Equality Act 2010 when it has a substantial and long-term effect on day-to-day activities. Employers have a duty to consider reasonable adjustments, but what is reasonable depends on the job, the workplace and the organisation. An adjustment does not have to remove every difficulty to be worthwhile.

The strongest requests are specific. Rather than asking generally for flexibility, explain the barrier and a possible change. For example, an earlier start may be harder if mornings involve stiffness or fatigue, while a later start may allow you to work more reliably. Home working can reduce the energy cost of commuting, but it may not suit everyone if isolation, pain or concentration are worse at home.

Useful adjustments may include:

• predictable hours, reduced hours or a phased return after absence;
• extra rest breaks, a quiet recovery space or permission to step away from sensory overload;
• home or hybrid working where the role allows it;
• changes to equipment, seating, workstation layout, parking or building access;
• written instructions, task prioritisation and extra time for complex work;
• flexibility around medical appointments and a clear plan for episodes or symptom flares.

For some roles, safety planning needs particular care. If you work at height, drive as part of your job, use machinery, work alone, handle hot equipment or are responsible for other people’s immediate safety, symptoms such as functional seizures, altered awareness, sudden weakness or visual changes need an honest discussion. This is not about excluding you from work. It is about reducing avoidable risk and considering whether duties can be changed.

Make a plan for fluctuating days

Many workplace policies are built around a simple idea of sickness: you are either off sick or fully well. FND rarely behaves that neatly. A flare can arrive without warning, and recovery may not follow a timetable. A written plan can stop every difficult day becoming a fresh negotiation.

Agree who you will contact if you cannot work, what information you are comfortable sharing, whether part-day working is possible and what happens if symptoms begin during a shift. If you have functional seizures or episodes, include practical, respectful instructions: how colleagues can keep you safe, when to give you space, whom to contact, and when to call emergency services.

Familiar symptoms can still be frightening, but new, severe or clearly different symptoms should not automatically be assumed to be FND. Seek urgent medical help for symptoms that are new, severe, or suggest an emergency, especially chest pain, serious injury, difficulty breathing, a prolonged loss of consciousness, or stroke-like symptoms that are not usual for you. Your workplace plan should reflect the advice you have been given by your own clinical team.

When work is no longer sustainable as it is

Sometimes adjustments make a job workable. Sometimes they do not, or not yet. Reducing hours, changing roles, taking sickness absence or leaving work can bring grief as well as relief. Employment is tied to identity for many of us, and it can hurt when your capacity changes. Needing support is not a personal failure.

Try not to make a major decision in the middle of a severe flare if you can avoid it. Ask for an occupational health referral where available, speak with your GP or relevant clinician, and gather evidence of how symptoms affect function. Keep copies of fit notes, appointment letters, adjustment requests and meeting notes. This can be helpful if you need to discuss benefits, sick pay, Access to Work, capability procedures or a return-to-work plan.

If an employer dismisses fluctuating symptoms because you looked well yesterday, write down what was said and follow up important conversations by email. You deserve to be treated with dignity, even when the process feels exhausting. A trusted friend, union representative, colleague or advocate may be able to attend meetings or help you prepare.

Build work around a life, not against it

There is no prize for making yourself smaller to fit a workplace that will not listen. Equally, work does not have to be all or nothing. Paid employment, self-employment, volunteering, retraining, study, a different role or a period focused on health can each be valid choices at different points.

Start with one practical step: note the part of work that drains the most energy, the change that could reduce it, and the person you need to speak to. You deserve a working life that recognises both your skills and the reality of your FND.
