The Fit Note Is a Starting Point, Not a Verdict: Mental Health and Work

A fit note is often treated as a verdict. In practice, it is a short administrative document that records a clinical opinion about work at a particular point in time. For mental health, that distinction matters. The note can support a conversation about absence, return and adjustment, but it cannot redesign a role, settle a dispute or substitute for occupational health advice.

A short document with a narrow job

Across the UK, the fit note - formally the Statement of Fitness for Work - is the main document used when someone has been off sick for more than seven days. For the first seven days, employees can usually self-certify. After that, a GP or another authorised healthcare professional may issue a fit note.

The document is not a detailed medical report. It is a brief record of whether a person is not fit for work, or may be fit for work with support. It may include a diagnosis or symptoms, but the clinically useful part is often the description of functional impact: what someone cannot do, what they can do with difficulty, and what might help.

A fit note is evidence. It is not an instruction to an employer, and it does not oblige an employer to accept every suggested change. Its value lies in starting a precise conversation rather than ending one.

'Not fit' and 'may be fit' are not the same message

The first distinction on the form is between 'not fit for work' and 'may be fit for work'. The first means the clinician's view is that the person should not be working at all during the stated period. The second means work may be possible if certain adjustments are made.

When 'may be fit for work' is selected, the fit note may suggest broad options: a phased return, altered hours, amended duties or workplace adaptations. These are prompts, not a full return-to-work plan. A GP may not know the detail of someone's job, the pace of the workplace or the practical limits of the employer's operations.

This is why the 'may be fit' box can be misunderstood. It does not mean the person is ready to resume all duties. It means the clinician believes a return could be considered with support. If no suitable adjustment is possible, the person may remain off work. The note should be reviewed rather than treated as a fixed contract.

What a GP can reasonably record

In a short appointment, a GP can reasonably record the patient's account of symptoms and functional impact, offer an opinion on work capacity, and suggest general adjustments. They can note that concentration is affected, that travel at peak times is difficult, that sleep is disrupted, or that a gradual increase in hours should be considered. They can also set a review date.

They cannot, in seven minutes, assess a workplace, observe someone performing their duties, determine whether a specific adjustment is operationally feasible, or produce a detailed functional capacity assessment. They are not there to adjudicate on management style, workload disputes or disciplinary matters. Those are not clinical questions, even when they affect mental health.

A GP also cannot declare that someone is disabled under the Equality Act 2010. That is a legal question, not a medical certificate. A fit note may support an employer's understanding, but it does not settle entitlement to reasonable adjustments.

Because time is limited, preparation helps. A concise written summary of the job's main demands and the tasks that have become difficult is often more useful than a long narrative. The patient should be clear about what they are asking the GP to record, and should ask what the proposed wording means if it is unclear.

What the note cannot settle

A fit note cannot force an employer to grant a particular adjustment. It cannot resolve a grievance, override a sickness absence policy or guarantee that a return will be successful. It cannot predict recovery with certainty. It is also not a substitute for a specialist report where complex or safety-critical work is involved.

Employers should not demand full medical records as a condition of considering adjustments. They may need enough information to understand the effect on work and to consider reasonable adjustments, but confidentiality still applies. The fit note should be handled as sensitive personal data.

Adjustments, evidence and the employer

For employees who meet the definition of disability under the Equality Act 2010, employers have a duty to make reasonable adjustments. Not every mental health condition will meet that threshold, but a fit note can still be the starting point for a supportive conversation.

Practical adjustments might include a temporary reduction in hours, a phased return, flexibility around start and finish times, changes to supervision or reporting lines, a quieter workspace, written instructions, additional breaks, time off for appointments, or a temporary change in duties. The right adjustment depends on the job, the person and the evidence available.

A fit note is most useful when it describes function rather than only diagnosis. 'Cannot manage customer-facing duties for four weeks' may be more actionable than a label alone. Even so, the employer must consider what is reasonable in its own context. A small business may have different practical limits from a large public sector employer.

When occupational health or a union representative helps

Occupational health becomes useful when the situation is complex, persistent or safety-critical, when adjustments are unclear, or when a phased return needs monitoring. An occupational health adviser can assess functional capacity and advise on adjustments, usually with the employee's consent. They do not make the final management decision, but they can provide a more detailed view than a short GP appointment allows.

A union representative can help with process: attending meetings, understanding sickness absence policies, requesting adjustments, keeping records and preparing for a return-to-work discussion. They are not a clinical adviser, but they can reduce the risk of the paperwork becoming adversarial. ACAS can also provide guidance where workplace disagreement persists.

A checklist for the appointment

• Note the main tasks and demands of the job, including hours, travel, screen work, customer contact and supervision.
• Describe the tasks that have become difficult, and why, with concrete examples.
• Say what has helped so far and what has not.
• Bring a short list of proposed adjustments, marked as temporary where appropriate.
• Ask the GP to record functional impact, not only a diagnosis.
• Ask what the fit note wording means, especially if 'may be fit for work' is chosen.
• Check the dates, the review period and whether the note will need to be sent to the employer.
• Keep a copy and note any agreed next steps.

The note as a beginning

A fit note is a small piece of paper with a limited job. It can open a conversation about work and mental health, but it cannot carry the whole conversation. The most useful notes are specific about function, realistic about time and clear about review. The most useful workplaces use them as evidence to think with, not as a weapon or a shield.

If the process becomes stuck, the next step is usually a review, a request for occupational health advice, or support from a union representative. The paperwork matters, but it is not the whole story.
