Will I get fired for being sick?
It is a question many employees ask when a few days of illness turn into a longer absence, when they have been off work several times, or when their employer starts talking about an absence review.
The short answer is: being sick does not automatically mean your employer can fire you.
However, UK employment law does not give an employee an unlimited right to remain in a job regardless of how long they are unable to work. In some circumstances, an employer may eventually consider dismissal because of ill health or an inability to perform the role. But dismissal for sickness should not simply be an automatic response to an employee being unwell.
GOV.UK says that dismissal because of long-term illness should be treated as a last resort. Employers should consider ways of helping the employee return to work, including flexible or part-time working, different duties, medical evidence and occupational health advice. If the employee is disabled, the employer must also consider reasonable adjustments.
This distinction is important.
There is a big difference between:
“I was ill for several days and my employer dismissed me.”
and:
“I have a long-term health condition, my employer followed a capability process, considered medical evidence and reasonable adjustments, and eventually decided I could not continue performing the role.”
The legal position can be very different.
This guide explains will I get fired for being sick in the UK, what your employer can do, what protections may apply, what happens with long-term sickness, and what you should do if you are worried about losing your job.
Can you be fired for being sick in the UK?
Yes, an employee can potentially be dismissed while off sick, including in some circumstances where the reason relates to their health.
But this does not mean an employer can simply dismiss someone because they have caught an illness or taken legitimate sick leave.
Acas explains that employment can end while someone is on sick leave, including where the employee’s illness means they are no longer capable of doing their job. However, employers should take steps to avoid dismissal on capability grounds and should look at ways to support the employee’s return to work.
GOV.UK similarly states that employers considering dismissal because of long-term illness should explore ways to help the employee return to work before treating dismissal as an option.
So if you are asking:
“Can my employer fire me just because I am sick?”
The answer is not simply yes.
The employer should consider the circumstances, the nature of your illness, your expected recovery, your ability to perform your role, your contract and policies, the effect on the organisation, medical evidence and any legal protections that apply.
Why does the length of your sickness matter?
Not every period of sickness is treated in the same way.
Being absent for three days because of flu is very different from being absent for six months following major surgery.
It is also different from having repeated short-term absences caused by an underlying disability.
An employer may have an absence management policy with review or “trigger” points.
For example, an employer’s policy might state that a certain number of absences within a particular period will lead to an absence review.
But reaching a trigger point does not automatically mean you should be dismissed.
Acas states that absence trigger points should start an absence review, rather than automatically trigger disciplinary action. Employers should consider the reasons for the absence and individual circumstances. They should also consider whether an absence is related to disability, pregnancy, mental health or another relevant factor.
This is an important protection.
A sickness absence review is not necessarily a dismissal meeting.
It may be an opportunity to discuss:
- Why you have been absent;
- Whether you are recovering;
- Whether further absence is expected;
- Whether you need support;
- Whether occupational health advice is appropriate;
- Whether adjustments could help;
- When you may be able to return;
- Whether a phased return is possible.
What if I am only off sick for a few days?
If you are genuinely unwell, short-term sickness absence is a normal part of employment.
Under current GOV.UK guidance, if you are off sick for 7 days or less, you generally do not need a fit note. You can normally self-certify your sickness absence using the employer’s required process. If you are ill for more than 7 days in a row, you normally need a fit note or another accepted form of medical evidence.
Your employer may have its own sickness reporting procedure.
You may need to:
- contact your manager;
- call a designated sickness line;
- report the absence before a particular time;
- provide an estimated return date;
- complete a self-certification form;
- provide a fit note after seven days.
The safest approach is to follow your employer’s absence policy.
Failing to follow the required reporting procedure can create a separate workplace issue, even where you were genuinely ill and Lawyer for False Accusations at Work in UK.
What happens if I am sick for more than 7 days?
If your sickness lasts more than seven days, you normally need a fit note.
A fit note can state that you are:
- Not fit for work, or
- May be fit for work.
Where a fit note says you may be fit for work, the employer and employee can discuss changes that might allow the employee to work. GOV.UK gives examples such as changes to hours or duties. If no agreement can be reached about those changes, the employee should be treated as not fit for work.
This is useful because returning to work does not always have to mean returning immediately to exactly the same working pattern.
Depending on the circumstances, a return might involve:
- Reduced hours;
- Lighter duties;
- Different working hours;
- Home working where appropriate;
- Temporary changes to responsibilities;
- A phased return;
- Additional support.
What is long-term sickness?
GOV.UK says an employee who has been off sick for more than four weeks may be considered long-term sick.
Long-term sickness can create difficult questions for both the employee and employer.
You may be asking:
“When will I be expected to come back?”
Your employer may be asking:
“When is the employee likely to return, and can we reasonably keep the role open?”
The answer depends heavily on the individual circumstances.
There is no simple rule saying:
“Six months sick = automatic dismissal.”
There is also no universal rule saying:
“An employer must keep your job open indefinitely.”
Instead, the employer should consider the available evidence and the possibility of a return to work.
Can an employer dismiss someone who is on long-term sick leave?
Potentially, yes.
But dismissal should normally be a last resort.
GOV.UK says employers should consider whether the employee can return to work, including through flexible or part-time work or different duties, and should consult the employee about when they might return and whether their health is expected to improve.
An employer may consider obtaining:
- A GP medical report, with the employee’s permission;
- An occupational health assessment;
- Other relevant medical information.
The employee has rights concerning access to a medical report obtained from their doctor.
The employer should then consider the available evidence before deciding what to do.
This is why an employee facing long-term sickness dismissal should not assume that receiving an occupational health referral means they are about to lose their job.
It can actually be part of the process of understanding what support or return-to-work arrangements may be possible.
What if my illness is a disability?
This can significantly change the legal position.
Under the Equality Act 2010, a person is generally disabled if they have a physical or mental impairment that has a substantial and long-term adverse effect on their ability to carry out normal day-to-day activities.
The law does not require every employee to have a condition that is immediately obvious to other people.
Mental health conditions and other non-visible impairments can potentially meet the legal definition depending on their effects and duration.
There are also special rules for certain progressive conditions and conditions including cancer, HIV and multiple sclerosis.
If you are disabled under the Equality Act, your employer may have a legal duty to make reasonable adjustments.
What are reasonable adjustments?
Reasonable adjustments are changes designed to prevent a disabled employee from being placed at a substantial disadvantage at work.
GOV.UK gives examples including:
- Changing working hours;
- Changing the way work is carried out;
- Providing equipment;
- Allowing a phased return;
- Allowing flexible or part-time working;
- Making physical workplace changes.
In relation to sickness absence, reasonable adjustments can sometimes involve the way absence is counted.
For example, Acas explains that where sickness absence is related to disability, an employer could consider adjusting absence trigger points or excluding some disability-related absence from the trigger calculation, depending on what is reasonable in the circumstances.
This can be extremely important.
Imagine an employee has a long-term condition that requires regular medical treatment.
They might have more absences than another employee.
If the employer simply applies a standard attendance trigger without considering the disability-related circumstances or reasonable adjustments, that may create a legal issue.
The employer should consider the individual situation.
Can you be dismissed if you have a disability?
Having a disability does not create an absolute guarantee against dismissal.
However, an employer cannot simply dismiss someone because they are disabled.
Acas states that employers must not dismiss or discipline someone simply because they are disabled and should make sure they have done everything reasonably possible to support the employee before considering formal action.
In some circumstances, dismissal may still be possible.
For example, an employer may eventually conclude that:
- The employee cannot perform the essential requirements of the role;
- Reasonable adjustments have been considered;
- Alternative arrangements have been explored;
- There is no suitable alternative role;
- Medical evidence indicates that a return is not realistically expected within a reasonable period;
- Continuing the employment would create significant operational difficulties.
But these questions are fact-specific.
The employer needs to consider the circumstances rather than simply counting sick days.
What if my employer uses sickness “trigger points”?
Many organisations use absence management systems.
A trigger point might mean that an employee’s absence is reviewed after:
- A certain number of separate absences;
- A certain number of days absent;
- A particular pattern of absence.
Acas confirms that there are no universal legal rules determining exactly when an employer must review absence. Employers may create their own systems, but they should apply them flexibly and sensitively.
Reaching a trigger should therefore not automatically mean:
“You are being fired.”
It usually means:
“Your attendance is being reviewed.”
During that review, you may have an opportunity to explain the circumstances and discuss support.
Can sickness absence become a disciplinary issue?
Sometimes.
There is an important difference between:
Capability
You are genuinely unable to work because of illness.
Conduct
There is an allegation that you have breached the employer’s rules, for example by failing to report absence correctly or providing dishonest information.
Acas notes that employers should consider whether the reason for absence is genuine. If they have reason to believe the absence is not genuine, they may need to address it as a misconduct issue.
This distinction matters.
If you are genuinely sick and have followed your employer’s reporting requirements, the situation may be a capability or absence-management matter.
If an employer believes you falsely claimed to be sick, that could become a conduct or disciplinary matter.
The two should not automatically be treated as the same thing.
What if I have been sick several times?
Repeated short-term sickness absence can become a workplace issue even where every individual absence was genuine.
An employer may need to understand:
- How often you have been absent;
- Whether there is an underlying health condition;
- Whether the absences are connected;
- Whether your attendance is affecting the business;
- Whether adjustments or support could help;
- Whether the attendance situation is likely to improve.
Acas says absence reviews should consider the cause of absence and whether there may be disability, pregnancy, mental health or other relevant circumstances.
If your repeated sickness is connected to a disability, reasonable adjustments may need to be considered.
What if stress or anxiety is making me sick?
Mental health can be relevant to workplace sickness law.
Stress, anxiety, depression and other mental health conditions may sometimes amount to a disability under the Equality Act depending on their effects and duration.
The legal question is not simply whether someone has received a particular diagnosis.
The Equality Act focuses on the impact of the impairment and whether it has a substantial and long-term adverse effect on normal day-to-day activities.
If your health is being affected by work, tell your employer what support you need where you feel able to do so.
Possible workplace measures could include:
- Temporary changes to workload;
- Flexible hours;
- Phased return;
- Changes to duties;
- Time for medical treatment;
- Occupational health assessment.
What is appropriate depends on the individual situation.
What if I am pregnant and off sick?
Pregnancy-related sickness can raise additional legal issues.
Pregnancy and maternity are protected characteristics under the Equality Act 2010.
Acas guidance also highlights that employers should consider pregnancy-related absence carefully and avoid applying ordinary absence policies in a way that creates discrimination.
If your sickness is connected to pregnancy, pregnancy-related conditions or maternity, do not assume that it should simply be treated in exactly the same way as unrelated sickness absence.
If you are concerned about dismissal or treatment connected with pregnancy, specialist employment advice may be appropriate.
What happens to your pay when you are sick?
Your sick pay depends on your circumstances and your employment contract.
There may be:
- Statutory Sick Pay (SSP);
- Contractual sick pay;
- Occupational sick pay;
- Other benefits depending on your circumstances.
There was an important change to SSP in April 2026.
From 6 April 2026, SSP became available to eligible employees regardless of earnings, and it became payable from the first full day of sickness absence. The rate for 2026–27 is £123.25 per week or 80% of average weekly earnings, whichever is lower.
This is separate from the question of whether an employer can dismiss someone because of sickness.
Receiving SSP does not itself create an unlimited right to remain employed.
Similarly, being absent from work does not automatically mean your employment ends.
Do you still build up holiday while off sick?
Yes.
GOV.UK confirms that statutory holiday entitlement continues to build up while an employee is off sick, regardless of how long they are absent. Statutory holiday that could not be used because of sickness may also be carried over into the next leave year in the circumstances covered by the rules.
This can become important during long-term sickness.
For example, an employee who has been away from work for several months should not simply assume that their annual leave entitlement has disappeared.
Can my employer make me take holiday because I am sick?
There is an important distinction between taking holiday and being on sick leave.
GOV.UK states that employers cannot force employees to take annual leave when they are eligible for sick leave. An employee can also ask to take paid holiday while off sick, although the normal rules around sickness still apply.
If you are dealing with long-term sickness, it is worth checking how your employer is recording your absence and holiday entitlement.
What should you do if you are worried about being fired for being sick?
Do not wait until you receive a dismissal letter before taking the situation seriously.
A few practical steps can help.
1. Check your employment contract
Look for:
- Sickness reporting requirements;
- Sick pay provisions;
- Absence procedures;
- Disciplinary rules;
- Capability procedures;
- Occupational health provisions.
2. Read the sickness absence policy
Find out whether your employer has formal trigger points.
3. Follow the reporting procedure
If the company requires you to call your manager by a particular time, follow that process.
4. Keep your medical evidence
Keep copies of relevant fit notes and correspondence.
5. Communicate honestly
If you do not know when you will return, do not invent a date.
You can explain that your recovery is still being assessed.
6. Ask about support
If you may be able to return with adjustments, discuss this with your employer.
7. Consider occupational health
An occupational health assessment can provide information about your ability to work and possible adjustments.
8. Keep records
Keep emails, letters, meeting invitations and notes of important conversations.
9. Ask questions before signing documents
If your employer gives you a settlement agreement or another legal document, understand what it means before signing.
10. Get advice if dismissal becomes a real possibility
This is particularly important if you have a disability, pregnancy-related sickness, a long-term condition or concerns about discrimination.
What if my employer says “your attendance is unacceptable”?
Do not panic.
Ask what the employer means.
Is the employer:
- Conducting an absence review?
- Considering capability?
- Starting disciplinary proceedings?
- Considering dismissal?
- Asking for medical evidence?
- Discussing adjustments?
These are not necessarily the same thing.
Ask for the relevant policy and understand the process.
If a formal meeting is scheduled, prepare your explanation carefully.
Explain:
- Why you were absent;
- Whether the illness is ongoing;
- What your doctor or healthcare professional has advised;
- Whether you expect to return;
- Whether adjustments could help;
- Whether the absence is related to a disability;
- Whether treatment is ongoing.
Keep the discussion factual.
Can an employer dismiss you while you are on sick leave?
Yes, dismissal can happen while someone is on sick leave.
But being on sick leave does not remove the employer’s legal obligations.
Acas specifically recognises that employment can end while an employee is off sick, including for capability reasons or redundancy. It also states that employers should take steps to support a return to work and must make reasonable adjustments where the employee is disabled.
If you receive a dismissal letter while you are sick, do not assume that the dismissal is automatically lawful or automatically unlawful.
Look at:
- The stated reason;
- The length and nature of your absence;
- The investigation;
- Medical evidence;
- Whether alternatives were considered;
- Reasonable adjustments;
- The employer’s policy;
- Your length of service;
- Whether discrimination may be involved.
What are your unfair dismissal rights?
The qualifying period for ordinary unfair dismissal is changing.
As of September 2026, the usual qualifying period remains two years for most ordinary unfair dismissal claims.
However, from 1 January 2027, the qualifying period for most employees will reduce to six months in England, Scotland and Wales. The reform does not apply in Northern Ireland, where employment law is devolved.
This is an important upcoming change for employees who are worried about job security.
However, unfair dismissal is not the only possible legal protection.
Some claims, including certain discrimination claims and automatically unfair dismissal claims, can have different qualifying requirements.
For example, disability discrimination protection does not depend on having completed two years of employment. Acas confirms that an employee can potentially bring a disability discrimination claim without the two-year service requirement that generally applies to ordinary unfair dismissal.
This is one reason why the exact reason for a dismissal matters.
What if I am dismissed because of my disability?
This may create potential Equality Act issues.
GOV.UK states that employers cannot discriminate against disabled employees and that protection covers areas including dismissal, redundancy, discipline and grievances. Employers also have a duty to make reasonable adjustments where required.
There can also be a legal issue where an employee is treated unfavourably because of something arising from their disability.
For example, the relevant issue might not be simply:
“You have a disability.”
It could involve:
“Your disability has caused absence, and you are being treated unfavourably because of that absence.”
The Equality Act contains specific protection against discrimination arising from disability, subject to its legal requirements and exceptions.
These cases are highly fact-specific.
What if my employer refuses reasonable adjustments?
If you believe you are disabled under the Equality Act and your employer has failed to consider reasonable adjustments, take the issue seriously.
Start by putting the request in writing.
Explain:
- the difficulty you are experiencing;
- the adjustment you believe would help;
- why the adjustment would help;
- any medical or occupational health evidence available.
Keep a record of the response.
An employer does not have to make every adjustment requested by an employee. The law concerns adjustments that are reasonable in the circumstances.
But simply refusing to discuss adjustments can create problems where the legal duty applies.
Can sickness dismissal be unfair even if you are genuinely sick?
Potentially.
The fact that you were genuinely sick does not automatically make a dismissal unlawful.
But an employer should be able to show that it has acted reasonably in the circumstances.
GOV.UK states generally that where an employee is dismissed, the employer must have a valid reason that can be justified and must have acted reasonably in the circumstances.
For long-term sickness, the employer should consider whether the employee can return, whether adjustments are possible and whether medical evidence supports the decision.
That is why the process matters.
What if I think my employer is trying to force me to resign?
This can be a particularly stressful situation.
If your employer is making your working conditions intolerable or pressuring you to resign because of your health, do not automatically hand in your resignation.
Resigning can have significant consequences.
Instead:
- Keep written evidence;
- Record what has happened;
- Raise concerns formally where appropriate;
- Check the grievance procedure;
- Obtain employment advice before resigning if the situation is serious.
A resignation made under pressure can potentially raise different legal questions, but constructive dismissal claims have specific requirements and should not be assumed simply because the workplace has become difficult.
When should you speak to an employment solicitor?
You do not necessarily need a solicitor every time you catch a cold.
Legal advice becomes more important when the situation moves from ordinary sickness management into a potential employment dispute.
Consider obtaining advice if:
- Your employer has threatened dismissal;
- You have been invited to a capability hearing;
- You are facing a final warning;
- Your employer is refusing reasonable adjustments;
- Your sickness is connected with a disability;
- You believe you are being discriminated against;
- Your sickness is pregnancy-related;
- You are being treated differently from colleagues;
- You are being pressured to resign;
- You have received a dismissal letter;
- You have been dismissed while off sick;
- Your employer has ignored important medical evidence;
- You believe the absence procedure was applied unfairly;
- You are considering an employment tribunal claim.
Early advice can be useful because employment disputes can involve strict deadlines.
Employment Tribunal time limits
If you believe your employer has acted unlawfully, do not assume you can wait indefinitely before taking action.
Many employment tribunal claims have a three-month time limit, although the exact calculation depends on the type of claim. Before bringing most employment tribunal claims, you normally need to go through Acas Early Conciliation.
The time limit can become particularly important where:
- You have already been dismissed;
- You believe discrimination occurred;
- You are considering a whistleblowing claim;
- You have suffered a workplace detriment;
- You have received a final decision following a grievance.
Internal appeals and grievances should not be allowed to make you lose sight of external legal deadlines.

Frequently Asked Questions
Will I get fired for being sick?
Not automatically. An employer can potentially dismiss an employee because of long-term incapability, but dismissal should generally be a last resort and the employer should consider support, medical evidence, alternatives and reasonable adjustments where applicable.
Can my employer fire me for one day of sickness?
A single day of genuine sickness does not automatically give an employer the right to dismiss you. However, the precise position depends on your employment status, contract, circumstances and reason for any proposed dismissal.
How long can I be off sick before I lose my job?
There is no universal UK rule saying that employment automatically ends after a particular number of sick days or months. Employers can consider capability in cases of long-term sickness, but should assess the individual circumstances and possible return-to-work options.
Can I be dismissed while on long-term sick leave?
Yes, dismissal can potentially happen during long-term sickness. However, employers should normally consider ways of supporting a return to work before treating dismissal as a last resort.
Can sickness absence count towards an attendance trigger?
It can, depending on the employer’s absence policy. However, Acas says employers should not use trigger points as an automatic reason for disciplinary action and should consider individual circumstances, including disability-related absence.
What if my sickness is caused by a disability?
If you meet the Equality Act definition of disability, your employer may have duties to make reasonable adjustments. Disability-related absence may also need to be treated differently when absence triggers are applied, depending on the circumstances.
Can I be dismissed because I have anxiety or depression?
Not simply because you have a mental health condition. Depending on the circumstances, anxiety, depression or another mental health condition may meet the Equality Act definition of disability. If so, disability discrimination and reasonable adjustment duties may become relevant.
Can my employer make me work when I have a fit note saying I am not fit for work?
If your fit note says you are not fit for work, you should discuss your situation with your employer. If a fit note says you may be fit for work, the employer should discuss possible changes with you. If no agreement can be reached about those changes, GOV.UK says you should be treated as not fit for work.
Do I still get holiday while off sick?
Yes. Statutory holiday entitlement continues to build up while you are off sick. Certain unused statutory holiday can also be carried forward where sickness prevented you from taking it.
What changed with Statutory Sick Pay in 2026?
From 6 April 2026, SSP became payable from the first full day of sickness absence for eligible employees, and eligibility was expanded regardless of earnings. For 2026–27, the rate is £123.25 per week or 80% of average weekly earnings, whichever is lower.
Does being off sick protect me from redundancy?
No. Sickness absence does not create an absolute protection against redundancy. However, an employer must follow applicable redundancy law and should consider whether sickness, disability or pregnancy-related circumstances create additional legal obligations. Acas notes that employers should keep employees who are off sick appropriately informed during redundancy processes.
What should I do if my employer says I will be dismissed because of my sickness?
Ask for the reason, evidence and procedure in writing. Check your employment contract and absence policy, prepare your medical information and consider obtaining employment-law advice before making a significant decision.
Final Thoughts: Can You Lose Your Job for Being Sick?
So, will you get fired for being sick?
Not simply because you caught an illness or needed legitimate time away from work.
But UK employment law also recognises that an employer may eventually need to consider dismissal where an employee cannot perform their role because of long-term ill health and there is no reasonable way to support a return.
The process matters.
Your employer should consider the circumstances, communicate with you, obtain appropriate medical information where necessary and explore reasonable alternatives before treating dismissal as the final option.
If you have a disability, the position can be more complex because the Equality Act 2010 may require reasonable adjustments and provides protection against disability discrimination.
The same applies where sickness is connected with pregnancy or where your absence forms part of a wider workplace dispute.
The best approach is not to panic and not to ignore the problem.
Check your policy. Keep your medical evidence. Communicate with your employer. Understand the process. Ask for appropriate support. And get legal advice if your job or legal rights are genuinely at risk.
Most importantly, do not assume that receiving an absence review letter means you are being fired.
An absence review may be the employer’s opportunity to understand what is happening and consider how you can return to work.
And if dismissal is eventually proposed, that is the point to look closely at the reason, evidence, procedure and any legal protections that may apply.
