Employees who believe their rights are being breached should consider obtaining independent advice from Acas, a trade union, an employment solicitor or an appropriate advice organisation.

Understanding Your Rights as a Disabled Employee

For many disabled people, employment is not simply a question of whether they are technically capable of doing their job.

The more important question may be:

Can they continue doing that job safely, sustainably and without their employment making an existing disability or health condition substantially worse?

This distinction becomes particularly important in physically demanding sectors such as retail, hospitality, warehousing and care work, where employees may spend many hours standing, walking, lifting, bending, carrying stock or repeatedly moving around large premises.

A disabled employee might desperately want to remain in employment while simultaneously finding that their condition is deteriorating.

They may experience severe or chronic pain during an eight-hour shift. Management might know about the disability. The employee may already have been offered occasional short breaks.

But what happens when those ten-minute breaks are no longer enough?

The law does not say that an employer has fulfilled all of its responsibilities simply because it has offered something. Reasonable adjustments need to address the disadvantage the disabled employee is actually experiencing, and adjustments may need to be reconsidered when circumstances or the person’s condition change.

Acas specifically advises that reasonable adjustments should be reviewed where an employee’s condition or impairment changes or where a disability becomes worse over time.

Disability at Work and the Equality Act 2010

The principal legislation protecting disabled employees in Great Britain is the Equality Act 2010.

Under Section 6 of the Act, disability broadly involves a physical or mental impairment that has a substantial and long-term adverse effect on a person’s ability to carry out normal day-to-day activities.

A person does not have to use a wheelchair, look visibly disabled or be unable to work to receive protection.

Many progressive, fluctuating, chronic and invisible conditions may fall within the legislation.

The Equality Act covers employment and protects disabled people in relation to matters including employment terms, training, promotion, disciplinary action and dismissal. Government guidance confirms that employers must not discriminate against employees because of disability.

Several provisions may become particularly relevant.

Section 20: Duty to Make Reasonable Adjustments

Employers have a duty to make reasonable adjustments where a disabled person would otherwise be placed at a substantial disadvantage.

Section 21: Failure to Make Reasonable Adjustments

A failure to comply with the reasonable-adjustment duty can amount to unlawful disability discrimination.

Section 15: Discrimination Arising from Disability

This provision can apply where a disabled person is treated unfavourably because of something arising in consequence of their disability, unless the employer can objectively justify the treatment.

This could become relevant, depending on the facts, where matters such as disability-related absence, reduced mobility, slower performance or inability to undertake particular tasks result in unfavourable treatment.

The precise application of these provisions is fact-specific, which is why individual legal advice can become important where a dispute develops.

“We Let You Take Ten-Minute Breaks” Is Not Necessarily the End of the Matter

An employer might genuinely believe it has helped by allowing an employee to sit down for ten minutes when their pain becomes severe.

That may be useful.

It does not automatically mean the reasonable-adjustment duty has been satisfied forever.

The important question is whether the adjustment removes or reduces the disadvantage experienced by the disabled worker.

Acas states that employers should consider whether an adjustment will remove or reduce the disadvantage, whether it is practical and affordable, and other relevant circumstances. The employer should discuss the issue with the disabled person rather than make assumptions.

Therefore, imagine an employee works an eight-hour retail shift involving prolonged standing and walking.

They are given a ten-minute break when their pain becomes unbearable.

They sit down.

Their pain eases slightly.

They then return to several more hours of standing and walking.

The fundamental problem may remain.

In that situation, it may be appropriate for the employee and employer to discuss whether different or additional adjustments are required.

What Reasonable Adjustments Could Be Considered in Retail?

There is no universal list because reasonable adjustments must reflect the individual employee, their condition, their job and the employer’s circumstances.

However, possibilities could include:

• Providing a suitable chair, stool or perch so the employee does not have to stand continuously;
• Allowing the employee to alternate regularly between sitting and standing;
• Providing more frequent rest periods rather than waiting until pain becomes intolerable;
• Allowing longer recovery breaks where medically appropriate;
• Changing shift lengths;
• Temporarily or permanently reducing hours where appropriate and agreed;
• Changing start or finish times;
• Avoiding consecutive long shifts;
• Rotating duties between physically demanding and less physically demanding tasks;
• Removing or reducing heavy lifting;
• Reducing unnecessary walking across large premises;
• Reallocating particular physical duties to another member of staff where reasonable;
• Providing an appropriate workstation or equipment;
• Allowing additional time for medical appointments and treatment;
• Modifying productivity targets where disability affects the manner or speed in which tasks can reasonably be completed;
• Temporarily changing duties during a deterioration or relapse;
• Considering a phased return following disability-related sickness absence; and
• Considering transfer to a suitable alternative role where one exists and where this would constitute a reasonable adjustment.

Government guidance specifically gives examples including changing working hours, providing equipment, changing duties and using phased returns.

Reasonable adjustment does not mean that an employee can demand any change whatsoever. What is reasonable will depend upon circumstances including effectiveness, practicality, cost, organisational resources and the impact on the business.

But neither should employers simply decide that because one small adjustment has been offered, no further conversation is necessary.

What If the Disability Is Getting Worse?

A worsening disability is particularly important.

An adjustment that worked six months ago may not work today.

Acas expressly advises employers and employees to review adjustments when a person’s impairment changes or where they are managing a disability that becomes worse over time.

That means the conversation should evolve with the person’s needs.

An employee could therefore write to their manager and explain:

• That their disability or symptoms have worsened;
• What happens during their working day;
• Which duties increase their symptoms;
• When the pain becomes particularly severe;
• Why existing adjustments are no longer sufficient;
• What adjustments they believe may help; and
• That they are formally requesting a review of their reasonable adjustments.

Putting the request in writing can be particularly valuable.

Acas recommends considering written requests because this creates a record of what has been requested and discussed.

What If There Is No HR Department?

Some workplaces have no dedicated Human Resources department.

That does not mean employment law disappears.

The legal duties belong to the employer.

In a workplace without HR, the employee may raise the matter with their:

• Line manager;
• Store manager;
• Area or regional manager;
• Owner or director;
• Designated senior manager; or
• Another person identified in the company’s grievance, disability, sickness or health-and-safety procedure.

Smaller businesses may also have no internal occupational-health service.

Acas acknowledges this. Where there is no occupational-health scheme, the employer can still communicate with the worker and, with the worker’s permission, seek appropriate medical information.

An absence of HR should therefore never be confused with an absence of responsibility.

Occupational Health Can Be Extremely Important

Where the employee and manager disagree about what someone can reasonably do, an occupational health assessment can be valuable.

Occupational health can consider matters including:

• How the health condition affects the person’s job;
• Which duties aggravate symptoms;
• Whether particular activities should be reduced;
• Possible reasonable adjustments;
• Equipment;
• Working hours;
• Shift patterns;
• Breaks;
• Temporary restrictions;
• Phased returns; and
• Whether the employee is medically able to continue performing particular duties.

Acas says occupational health can help an employer determine suitable reasonable adjustments for a disabled employee and assist where someone is struggling with physical or mental health at work.

The objective should not simply be:

“Can this person force themselves through today’s shift?”

A more constructive question is:

“What changes might allow this employee to remain in employment safely and sustainably?”

The Employer Also Has Health and Safety Responsibilities

Disability discrimination legislation is not the only law potentially relevant.

Under Section 2 of the Health and Safety at Work etc. Act 1974, employers have a duty, so far as reasonably practicable, to ensure the health, safety and welfare of their employees at work.

The Management of Health and Safety at Work Regulations 1999 also contain requirements concerning workplace risk assessment.

The Health and Safety Executive advises employers that when they become aware of a disabled worker, they should review their existing risk assessment to ensure it adequately covers risks affecting that person. HSE stresses that employers should consider people’s individual circumstances rather than making assumptions about disability.

Where management knows an employee is repeatedly completing shifts in extreme pain, it is reasonable for questions to be asked about both reasonable adjustments and workplace risk management.

Sick Leave May Be Necessary, But It Does Not Necessarily Solve the Problem

There may come a point where someone’s health means they genuinely cannot continue working temporarily.

Taking sickness absence in those circumstances should not be regarded as failure.

For absences lasting more than seven calendar days, a registered healthcare professional can issue a fit note. Fit notes can state either that someone is not fit for work or may be fit for work subject to appropriate measures.

A “may be fit for work” recommendation can potentially identify measures such as:

• Altered hours;
• Amended duties;
• Workplace adaptations;
• Flexible working; or
• A phased return.

Acas states that an employer should carefully consider recommendations made on a fit note. Where recommendations amount to reasonable adjustments required for a disabled employee, the employer must put reasonable adjustments in place.

However, long-term disability raises a much bigger issue.

Sickness absence may provide valuable time to recover from an acute deterioration, treatment or relapse.

But if the underlying condition is chronic, progressive or incurable, simply repeatedly sending the employee home sick does not necessarily address the workplace barrier.

The employee may return to exactly the same environment and exactly the same physical demands.

That is why a discussion about long-term sustainable adjustments can be so important.

Disability-Related Sickness Absence May Also Require Adjustment

Employers should also be careful about how disability-related absence is treated.

Acas gives examples of possible reasonable adjustments including:

• Recording disability-related absence separately;
• Discounting some disability-related absences from ordinary absence trigger points; or
• Increasing the level of absence that triggers a formal review.

Whether such measures are reasonable will depend upon the circumstances.

Automatically treating disability-related absence exactly like unrelated ordinary sickness can, in some circumstances, create problems under the Equality Act.

Access to Work

Employees should also know about the government’s Access to Work scheme.

Access to Work can help disabled people remain in employment by contributing towards additional practical support associated with disability, which can include specialist equipment, adaptations and other forms of workplace assistance.

However, there is an important distinction.

Access to Work does not replace an employer’s legal responsibility to make reasonable adjustments.

Government guidance states that Access to Work support is intended to complement rather than subsidise the reasonable adjustments an employer is legally required to provide.

What Can the Employee Actually Do?

For an employee who is already struggling, employment law can seem overwhelming.

A sensible progression might therefore be:

1. Keep a Written Record

Document significant incidents, including:

• Dates;
• Shift lengths;
• Duties performed;
• Requests for assistance;
• Pain or other symptoms experienced;
• Responses received from management;
• Adjustments provided;
• Occasions when adjustments were refused; and
• Relevant emails or messages.

This is not about starting a confrontation.

It creates an accurate record.

2. Formally Notify Management That the Condition Has Worsened

Even where management already knows about the disability, the employee should consider stating clearly that their symptoms or functional limitations have changed.

3. Request a Reasonable-Adjustment Review in Writing

Explain why the present arrangement is inadequate and identify possible alternatives.

The employee does not necessarily need to design the entire solution themselves. Adjustments should ideally be discussed collaboratively.

4. Request Occupational-Health Input

If there is no internal occupational-health department, an external occupational-health assessment may still be possible.

5. Consider Medical Evidence

A GP, consultant, physiotherapist, occupational therapist or other appropriate healthcare professional may be able to explain functional limitations or make recommendations.

The employer does not automatically require access to someone’s complete medical history.

6. Consider Access to Work

Where support goes beyond the employer’s ordinary reasonable-adjustment responsibilities, Access to Work may provide additional assistance.

7. Raise a Formal Grievance if Informal Requests Are Going Nowhere

Where an employer repeatedly fails to address concerns, the employee can consider using the organisation’s formal grievance procedure.

No HR department is required for a grievance to exist.

It can be addressed to an appropriate senior manager or employer.

8. Speak to Acas

An employee does not have to wait until they have lost their job before contacting Acas for information about workplace rights and options.

Acas provides guidance about reasonable adjustments, disability discrimination, grievances and employment disputes.

Contacting Acas for advice does not mean an employee is automatically launching legal proceedings against their employer.

What If the Employer Still Does Nothing?

Where an employer knows, or could reasonably be expected to know, that an employee is disabled and fails to make reasonable adjustments, the situation may potentially amount to disability discrimination.

Acas confirms that an employee can initially raise the matter informally or formally and, if matters remain unresolved, may ultimately consider an employment tribunal claim.

Employment tribunal deadlines are extremely important.

As at 22 September 2026, the normal limitation period for most employment tribunal claims remains three months minus one day.

However, this is about to change.

For limitation periods beginning on or after 1 October 2026, the time limit for most claims will increase to six months minus one day under changes introduced by the Employment Rights Act 2025. Acas confirmed the implementation date in updated September 2026 guidance.

Employees should never assume that an internal grievance pauses a tribunal deadline.

It does not.

Someone contemplating a tribunal claim normally needs to notify Acas within the applicable deadline. Acas Early Conciliation can then pause the limitation clock while the conciliation process takes place.

Individual legal advice should be obtained where limitation may be an issue.

A Disabled Employee Should Not Have to Reach Breaking Point Before Someone Listens

Perhaps the most troubling aspect of workplace disability is when everybody can see that an employee is struggling, yet the employee continues because they do not want to lose their livelihood, disappoint colleagues or be regarded as incapable.

Some people become extraordinarily good at masking pain.

• They smile at customers.
• They complete their shift.
• They go home.

And only those closest to them know how much physical effort it took to get through the day.

Being capable of enduring something does not necessarily mean that it is safe, reasonable or sustainable.

Employers should therefore avoid treating attendance itself as evidence that an employee must be coping adequately.

Someone can be attending work while simultaneously experiencing a serious deterioration in their quality of life.

Disability Inclusion Means Keeping People in Work, Not Merely Keeping Them on the Rota

Reasonable adjustments are not special treatment.

Their purpose is to address disadvantages created when a workplace designed around non-disabled workers encounters somebody whose disability means they cannot work in exactly the same way.

• A chair may make the difference.
• Different duties may make the difference.
• Shorter shifts may make the difference.
• A different pattern of breaks may make the difference.
• Reducing prolonged standing may make the difference.
• Listening may make the difference.
• And sometimes a combination of adjustments is needed.

The objective should not be to find the smallest concession an employer can make.

It should be to determine what reasonable and effective measures could enable a disabled employee to work without unnecessarily sacrificing their health in order to earn a living.

A progressive or lifelong condition does not necessarily mean the end of somebody’s working life.

But pretending that worsening symptoms do not require the workplace to adapt is not a sustainable solution either.

Where circumstances change, the conversation about reasonable adjustments should change with them.

Conclusion

A disabled employee experiencing worsening symptoms does not necessarily face only two choices:

Continue working in severe pain
or
Go on long-term sick leave.

There may be a third route: meaningful workplace adjustment.

The Equality Act 2010 places responsibilities on employers to consider reasonable adjustments. Health and safety legislation places additional responsibilities upon employers to protect workers from workplace risks. Acas guidance makes clear that adjustments may need to be reviewed where a disability worsens.

Ten minutes sitting down may help someone survive the next hour.

But where an eight-hour shift repeatedly causes severe pain, employers should be prepared to ask a much bigger question:

What needs to change so this employee can continue working safely, fairly and with dignity?

That is where genuine disability inclusion begins.
