Sickness delaying a disciplinary process
It is a scenario that many HR professionals and managers will recognise, just as you begin to investigate a disciplinary matter or schedule a disciplinary hearing, the employee reports themselves as sick. Frequently the sickness absence reason will relate to the formal procedure that is already underway, for example stress or anxiety.
This understandably can create uncertainty for the employer about whether to proceed, postpone, or pause the process altogether. The situation calls for delicately balancing fairness and the employee’s health, with the need to manage the conduct concerns in a timely manner, whilst working within the framework of your Disciplinary Policy and the ACAS Code of Practice, which collectively can be tricky to navigate.
In this article we look at some best practice steps to consider if you find yourself in this situation, where an employee’s sickness is delaying a disciplinary process.
Pause and assess the situation
Firstly, it is advisable to acknowledge the sickness absence, seek to understand the reason and maintain contact in a sensitive, non-pressurising way. If the employee hasn’t already provided one, you should request a fit note after the initial 7 calendar days self-certification period.
Secondly, assess whether the illness is short-term or likely to be longer-term, and whether it affects the employee’s ability to engage in the process. The fit note and conversations with the employee may give you an indication of these factors.
Not all sickness absence reasons make continuing with the disciplinary process inappropriate, for example physical health issues may mean the employee is still fit to engage in the process. If, however, the sickness is mental health related, you should take particular care to handle the matter sensitively and avoid exacerbating the employee’s condition.
Balancing fairness and business needs
Employers have a duty to act reasonably, but this does not mean disciplinary proceedings must be put on hold indefinitely.
If the employee informs you that they are not fit to engage in the formal process, the following steps can help maintain balance:
- Pause briefly to allow for the employee’s recovery (for example 2-3 weeks). If it is a short-term illness, it is usually appropriate to postpone the hearing until the employee recovers.
- Offer alternative options to assist the employee to more comfortably engage in the process. For example, meetings to be held remotely or at a neutral venue and at a time suitable to them. Ask the employee if they have any suggestions about potential support mechanisms that you can put in place to assist them in contributing.
- If the employee remains unwell, continues to inform you they are not fit to engage in the process by any means, and the situation is prolonged, it is advisable to obtain an occupational health report.

Consider reasonable adjustments
If the employee’s sickness relates to a potential disability (i.e. has a substantial and long-term adverse effect on their ability to carry out normal day-to day activities) the employer has a duty to make reasonable adjustments to the process. Where the disability status is unclear it is advisable to err on the side of caution in your approach.
Even where there is no evidence or indication of a disability, a good employer will still consider making reasonable and compassionate adjustments, as part of fair practice.
This might include:
- Allowing extra time to respond;
- Permitting written submissions instead of attendance;
- Arranging any meetings and the hearing at neutral venue or virtually;
- Provide written questions instead of an in-person hearing;
- Allowing a representative to attend on the employee’s behalf.
Adopting a supportive approach in all cases helps maintain trust with the employee and can help the process to run more smoothly. Failing to make reasonable adjustments where a disability exists could amount to disability discrimination, even if the employer’s intention was to proceed fairly.
Take medical and legal advice before proceeding
If occupational health or a doctor states that the employee is fit to engage in the disciplinary process (even if not fit for work duties), then it is usually reasonable to proceed, whilst observing any recommendations occupational health provide on how best to do so.
If, however, the medical advice indicates that participation would negatively impact the employee’s health, the employer should delay the process or explore alternatives such as written submissions, if they haven’t already done so. Proceeding against medical advice is high risk and could expose the business to claims of unfair dismissal, constructive dismissal, or disability discrimination under the Equality Act 2010.
If medical evidence suggests that the employee will not be fit to attend a hearing within a reasonable timeframe, employers can consider proceeding in the absence of the employee, provided the employee:
- Has been informed of the allegations;
- Has been given a fair chance to respond in writing; and
- Has been offered representation and support.
The hearing chairperson should carefully document the reasoning behind continuing in the employee’s absence, referencing the efforts made to accommodate their participation. In such cases, we recommend you seek legal advice before proceeding.
Keep records and maintain communication
In instances where an employee goes off sick during a formal disciplinary process clear, compassionate communication is essential. Keep the employee informed of:
- Any postponements
- The need for medical advice; and
- Any decisions to proceed without them.
All correspondence and decisions should be documented in case the matter is later challenged by the employee.
Summary
You don’t have to abandon disciplinary action when an employee goes off sick, but you must handle it sensitively and reasonably. A short delay or practical adjustments often help the employee to engage in the process and demonstrates fairness.
One of the most common pitfalls we see is managers allowing frustration, emotion, or personal judgement to influence how they handle the matter. It is natural to feel disappointed when a disciplinary process is delayed, but decisions should be grounded in facts and evidence, not assumptions about the employee’s motives and behaviours. When emotions cloud judgement, employers risk losing objectivity and failing to follow a fair process, which can turn a manageable issue into a legal one.
