Can I be sacked for being off sick in the UK?

Many employees think “Can I be sacked for being off sick in the UK?” and the answer is, it depends, your employer can dismiss you for being off sick but your employer must have a fair reason for taking the decision of dismissing an employee.

Here we will talk about fair reasons for dismissal and your employment rights if you are worried about being dismissed.

According to the website “You can be dismissed if you have a persistent or long-term illness that makes it impossible for you to do your job.”

However, before your employer considers the dismissal for being off sick, they need to take action to look for ways to support you or give you a reasonable time to recover.

Although, your contract of employment will normally include what are your rights in terms of company sick pay policy and over what period.

If there is no information stipulated about company sick pay, you may be entitled to Statutory Sick Pay (SSP).

The amount of time covered by SSP is generally 28 weeks in a 3 year period and the sick pay amount presently is £95.85 per week.

Fair reasons for dismissal

Your conduct

If you have been fired because of your conduct, it usually means that you have broken one or more of the terms included in your employment contract.

For instance, if you have been continually missing work, poor discipline, drug and/or alcohol abuse, theft, dishonesty, etc.

However, whatever the reason is, your employer should follow a disciplinary process before letting you go.


This refers to your ability to do your job, meaning that if you have been dismissed for your capability then your employer thinks you aren’t performing your job to the required standard or you haven’t been able to perform your job properly.

Here are some examples from

  • you haven’t been able to keep up with technological changes to your job
  • you can’t get along with your colleagues
  • long-term or persistent illness makes it impossible for you to do your job

However, your employer should have provided adequate training to do your job or if you are performing poorly, they should have warned you about how your job wasn’t satisfactory, giving you a chance to improve before letting you go.

Being off sick

It is true that most employers consider that having employees off sick is not profitable for their business, however, it is something they can’t actually control.

If you have been sick for a long period of time (usually more than 4 weeks), your employer should have looked at alternatives before dismissing you.

For instance, if your employer has determined your job is the one making you sick then, it needs to be changed.

However, as we have mentioned, your employer can dismiss you if you are off sick.

Normally, your employer would allow a reasonable amount of time for you to recover from your illness but the amount of time will depend on things like how long will you take to recover or if it is certain that you will recover.

Consider how if you have a long-term illness considered as a disability, which is the case for depression, your employer has a legal duty to try to find a way to get around the problem.

They must make what it’s considered “reasonable adjustments” to your workplace.

If they dismiss you when having a disability it can be considered discrimination.


This means being dismissed from your job because your employer needed to reduce their workforce.

Here are some reasons from

  • new technology or a new system has made your job unnecessary
  • the job you were hired for no longer exists
  • the need to cut costs means staff numbers must be reduced
  • the business is closing down or moving

You have the right of being treated fairly if you are being made redundant and your employer has several responsibilities towards you to make sure this happens. 

A statutory restriction

Your employer is entitled to a fair dismissal if you keep breaking the law.

According to the website “You can be dismissed if continuing to employ you would break the law – for example, if you’re a driver in a lorry firm and you lose your driving license.”

Some other substantial reason

This applies to a situation where your employer has an “overwhelming reason” why you must be dismissed.

However, they are expected to look at other alternatives before deciding a dismissal.

Some of the reasons that fall into this category include:

  • Imprisonment.
  • An unresolved personality clash between you and a co-worker.
  • Unreasonably refusing to accept a company reorganization that changes your employment terms

Unfair dismissal following sickness

If you have been employed for at least 2 years, you are protected against unfair dismissal, and you can bring a claim in the employment tribunal to enforce the protection after being fired for being off sick.

If you have more than 2 years working for your employer and you were dismissed unfairly, your employer will need to show they had a potentially fair reason for dismissing you or that they acted reasonably in the circumstances.

According to Ben Power from, “Capability, i.e. the ability to do the job, is a potentially fair reason which would cover sickness. Where absences are for unconnected health reasons (rather than an underlying condition), the employer may dismiss for some other substantial reason (SOSR). In this circumstance, they may argue that the disruption caused by the employee being off work can no longer be effectively managed and is damaging the employer’s business.”

Fair dismissal procedure

According to Ben Power from Spinghouselaw, “The ACAS Code on disciplinary and grievance procedures does not apply to capability dismissals for ill-health.  However, this does not mean that an employer is excused from going through a procedure prior to dismissal.”

In the case of long-term ill-health your employer should attempt to obtain your medical report to establish the prognosis and the course of your illness, to determine whether or not there is likely to be an improvement and when it is expected.

Moreover, your employer must exhaust all the options available when making adjustments (ideally in consultation with the employee) that might be able to assist you in returning to work.

You should get appropriate warnings that your employer will consider dismissing you, before they actually do.

In the cases of short-term absence, your employer should be expected to carry out a fair review of attendance records and the reason for your absence.

In addition, they should consult and talk to you and give you the opportunity to make representations and you should receive the appropriate warning about the dismissal if things don’t improve.

Your rights during sick leave

  • Your employer must keep in contact with you throughout your illness to ask about your welfare.
  • They must ask for your consent to obtain your updated medical records related to your prospects of returning to work.
  • You will remain an employee until you are able to return to work, unless you are questioned about your capability to perform your job.
