On Long-Term Sick? What Support Should Your Employer Provide – and What Are Your Rights?
Being off work for a long period because of ill health is difficult enough.
But for many employees, the illness itself quickly becomes only part of the worry.
How long will my employer keep my job open?
Why does HR keep contacting me?
Do I have to attend Occupational Health?
Should they be discussing reasonable adjustments with me?
Can they start a capability process while I am still ill?
And perhaps the question people are most frightened to ask:
Can my employer eventually dismiss me because I am off sick?
The short answer is that long-term sickness does not give you unlimited protection from dismissal.
But nor should an employer simply move from “you’ve been off for a long time” to “we’re ending your employment” without properly understanding your health, considering your ability to return and, where appropriate, looking seriously at reasonable adjustments and alternatives.
The process between those two points can be extremely important.
And if your health condition amounts to a disability under the Equality Act 2010, additional legal protections may apply.
What counts as long-term sickness?
Government guidance generally describes an employee who has been off sick for more than four weeks as being long-term sick.
But in practice, employers will usually manage absence according to their own sickness or attendance policy.
That means the process can vary considerably between organisations.
Some employers have sophisticated Occupational Health arrangements, rehabilitation programmes and structured return-to-work processes.
Others have little more than a sickness policy and a manager trying to work out what to do next.
Either way, being absent does not mean that the employment relationship simply stops.
You remain an employee, and both sides still have responsibilities.
What support should you expect?
This is where I would distinguish between what an employer must do and what a good employer should do.
There is no single legal checklist requiring every employer to provide exactly the same package of support.
However, you should normally expect an employer managing long-term sickness properly to maintain appropriate contact, seek to understand your likely prognosis and ability to work, consider medical or Occupational Health advice where appropriate and explore whether there are practical ways of supporting your return.
That may include discussing changes to hours, duties or working arrangements.
If your condition amounts to a disability under the Equality Act, the employer may also have a legal duty to make reasonable adjustments where the relevant requirements are met.
That is much more than simply being sympathetic.
What is Occupational Health actually there to do?
Employees sometimes become nervous when an Occupational Health referral is suggested.
They think:
“Are they trying to prove I’m incapable of doing my job?”
Sometimes an OH referral happens because an employer genuinely wants expert advice about how someone can be supported back into work.
It can also help an employer understand whether somebody is fit for their role, what restrictions might exist, whether adjustments should be considered and whether there is an indication of when a return may be possible.
Occupational Health can therefore be very useful.
But it is important to understand the context in which the referral is being made.
What questions is the employer asking?
What issue are they trying to understand?
How does the referral fit into the wider absence process?
An OH report can influence important employment decisions, so it should not simply be treated as another administrative form.
What are reasonable adjustments?
If your health condition meets the legal definition of disability, your employer may have a duty to make reasonable adjustments to avoid you being placed at a substantial disadvantage.
That could potentially involve things such as altering working hours, changing aspects of the working environment or providing equipment.
But the word reasonable matters.
It does not mean an employee can dictate whatever arrangement they would prefer.
What is reasonable depends on the circumstances, including the disadvantage being addressed, how effective the proposed adjustment would be, practicality, cost and the employer’s resources.
For some employees, an adjustment might be relatively straightforward.
For others, particularly where the role itself has significant physical, operational or attendance requirements, the position may be more complicated.
This is why simply saying “I want reasonable adjustments” often isn’t enough.
The real question is:
What is preventing you from working, and what could reasonably be changed to reduce that disadvantage?
What if your fit note says you “may be fit for work”?
This is an important distinction.
A healthcare professional can state that you are not fit for work, or that you may be fit for work taking account of certain advice.
Where a fit note says you may be fit, the employer should discuss whether changes could help you return.
If suitable changes cannot be agreed, government guidance says the employee should be treated as not fit for work for the period covered by the fit note.
A fit note therefore does not automatically dictate what the employer must do.
It should form part of a conversation about what is realistically possible.
What contact should your employer have with you?
This is another area where problems regularly arise.
Some employees tell us:
“I’m off sick, but my manager keeps contacting me. Surely they should leave me alone?”
Others experience the opposite:
“I’ve been off for three months and nobody has contacted me. I feel completely forgotten.”
Neither extreme is necessarily helpful.
Government and ACAS guidance supports maintaining appropriate contact during sickness absence.
The nature and frequency of that contact should be sensible and take account of the circumstances.
If someone is absent with work-related stress, for example, repeated calls from the manager involved in the situation may make matters worse.
That doesn’t necessarily mean all communication must stop.
It may mean agreeing who should make contact, how often and for what purpose.
Good absence management should feel like communication, not surveillance.
Can your employer dismiss you while you are long-term sick?
Potentially, yes.
This is one of the most important misconceptions around long-term sickness.
An employer is not necessarily required to keep a position open indefinitely.
Government guidance recognises that dismissal can ultimately occur where somebody is long-term sick, but describes dismissal as a last resort.
Before reaching that stage, an employer should consider matters such as whether the employee could return flexibly or part-time, whether different or less stressful work might be possible, and should consult with the employee about their likely return and whether their health is expected to improve.
Where disability is involved, the Equality Act and reasonable-adjustment obligations become particularly important.
There may also be unfair dismissal considerations depending upon the employee’s circumstances and the process followed.
So the question should rarely be simply:
“How many months have they been absent?”
The much more important questions are what the medical position is, whether a return is realistically foreseeable, what adjustments or alternatives have been considered and whether a fair process has been followed.
What is happening on the employer’s side?
This is where our experience at TrustForce gives employees a different perspective.
Once absence becomes prolonged, an employer will usually start considering several things at the same time.
What does the medical evidence say?
Is there a likely return date?
Can the employee fulfil the essential requirements of their role?
Could adjustments make a return possible?
How long can the current arrangements continue?
What impact is the absence having operationally?
Does the condition potentially amount to a disability?
And has the organisation followed its own policy?
That doesn’t mean the employer has already decided to dismiss you.
But it does mean the situation may gradually move from supporting an absence towards assessing longer-term capability.
Recognising when that shift is happening can be important.
The language may start changing.
Meetings may become more formal.
Occupational Health questions may become more focused on prognosis and long-term capability.
HR may become more involved.
You may be invited to a formal absence or capability review.
None of those things automatically means your job is about to end.
But they are signs that you should understand exactly where you are in the process.
What about sick pay?
There was an important change this year.
For sickness absences starting on or after 6 April 2026, eligible employees can receive Statutory Sick Pay from the first full day of sickness absence rather than having to serve the previous waiting period.
The lower earnings limit has also been removed.
SSP is now paid at 80% of normal weekly earnings or £123.25 per week, whichever is lower, subject to the statutory rules.
Your employer may provide more generous contractual or occupational sick pay, so your contract and sickness policy remain important.
Employees also continue to accrue statutory holiday entitlement while they are off sick.
Don’t wait until a capability meeting to understand the process
One of the biggest mistakes employees can make is waiting until the process becomes formal before asking what their employer has actually been doing.
If you’ve been absent for some time, understand the paperwork surrounding your absence.
Read the sickness or attendance policy.
Understand what your fit notes actually say.
Know what Occupational Health has recommended.
Keep track of adjustments that have been discussed.
And pay attention if the tone of conversations starts changing from “How can we support you?” towards “When will you be capable of returning to your substantive role?”
That change can be significant.
You don’t need to assume the worst.
But you should understand the process you are in.
Frequently asked questions
Does long-term sickness automatically count as a disability?
No. The legal definition of disability depends on the circumstances and the effect of the condition. Some conditions, including cancer, HIV and multiple sclerosis, are treated as disabilities from diagnosis. Other conditions need to meet the Equality Act definition.
Do I have to attend Occupational Health?
An employer may reasonably seek medical information to understand your fitness for work and how it should manage your absence. The precise position depends on your circumstances and employment arrangements. Before refusing, it is worth understanding why the referral has been requested and what consequences could follow if the employer has to make decisions without up-to-date medical advice.
Can my employer make me return before I am fully recovered?
A return does not always require somebody to be 100% recovered. A fit note may indicate that you could work with appropriate support or changes. Whether that is workable needs proper discussion.
Can my employer eventually dismiss me because of ill health?
Potentially, yes. But long-term ill-health dismissal should generally be a last resort and the employer should properly consider the medical position, consultation, possible return, alternatives and relevant reasonable adjustments before reaching that point.
You don’t have to work this out alone
Being on long-term sickness can leave employees feeling particularly vulnerable because decisions are often being made at a time when they are least equipped to deal with workplace processes.
At TrustForce, we can help you understand what stage your employer has reached, what questions are being asked, what your Occupational Health evidence actually means in the employment context and whether the support being offered appears appropriate.
Sometimes having someone independent look at the whole picture before the next meeting can make all the difference.
