When an employee doesn’t turn up to work - and you don’t know why - it’s natural to feel concerned, both for their welfare and the impact on your business. Unauthorised absence, also known as absence without leave or unexplained absence, can be a tricky issue for business owners and managers to deal with.
You want to ensure fair treatment, avoid legal trouble, and keep your team on track. But can you just dismiss someone for going AWOL? What are your legal obligations? And how do you handle these situations without risking an unfair dismissal claim?
Let’s break down exactly what you need to know about managing unauthorised absences, the right steps to take, and how to protect your business if things don’t improve.
What Is An Unauthorised Absence?
An unauthorised absence occurs when an employee misses work without prior permission or fails to provide an acceptable explanation. It’s sometimes called “unplanned absence”, going “AWOL” (absent without leave), or “absence without leave”.
- Not calling in or emailing when absent due to illness or personal emergency
- Taking unauthorised holiday or time off (e.g. leaving early or arriving very late without consent)
- Failing to return to work after agreed leave
- Going missing for several shifts or days
Essentially, if you as the employer don’t know where your employee is, why they’ve missed work, and haven’t given your consent, this qualifies as unauthorised absence.
Employers may feel frustrated or even anxious when this situation comes up - but as we’ll cover, it’s important not to jump straight to disciplinary action or dismissal.
How Should Employers Respond To Unauthorised Absence?
If you discover an employee hasn’t shown up to work and hasn’t provided a reason, don’t panic. It’s important to take a calm, step-by-step approach to ensure a fair process:
- Reach Out Immediately: Try to contact the employee via phone, email or text as soon as possible. This demonstrates you’re concerned for their wellbeing and gives them the chance to explain their absence.
- Document Your Efforts: Make a note of the methods and times you tried to contact them - accurate records can help if things escalate.
- Allow Reasonable Time For Response: People do sometimes face sudden emergencies, illness, or communication problems, so give the employee a chance to reply. What’s “reasonable” depends on the length of absence and your business needs, but an initial period of 24-48 hours is typical.
- Check Your Policies: Refer to your staff handbook, employment contracts, or absence policies to confirm your business’s specific procedures for unexplained absences. If you don’t have policies in place, it’s a good idea to create clear guidelines for the future.
- Carry Out An Investigation: If the employee fails to contact you, or if the reasons given aren’t satisfactory, you should begin a formal investigation before considering any disciplinary action.
Unexplained absences can sometimes result from genuine circumstances - family emergencies, mental health crises, or even domestic violence. A compassionate initial response both supports your team and helps protect your business legally.

What Is The Disciplinary Procedure For Unauthorised Absence?
British employment law requires that you follow a fair and transparent disciplinary process before considering dismissal for unauthorised absence. This is essential to protect your business from claims of unfair dismissal.
Here’s how a standard process might look:
- Investigation: Look into the details of the absence. Did the employee have a legitimate reason? Did they try to inform you? Was there an emergency or mitigating circumstance?
- Invite The Employee To A Disciplinary Hearing: If the absence remains unexplained or the reason is not satisfactory, arrange a meeting with the employee to discuss the incident. They should have the opportunity to respond to any allegations, and may bring a companion.
- Consider The Employee’s Explanation: Listen to their side of the story and assess whether the absence should be treated as misconduct.
- Make A Decision And Communicate It: Decide on the appropriate action, which may range from informal counselling or a written warning, through to final written warning or dismissal in very serious cases.
- Provide A Right Of Appeal: The employee should always be given a chance to appeal any disciplinary decision, especially if dismissal is on the table.

Can You Dismiss An Employee For Unauthorised Absence?
The short answer: yes, you can dismiss an employee for unauthorised absence - but only after a fair process.
Jumping straight to dismissal, especially without prior warnings or giving the employee a proper chance to explain, is likely to lead to legal claims of unfair dismissal under the Employment Rights Act 1996 or the ACAS Code of Practice on disciplinary procedures.
In most cases, dismissal for a single instance of absence without leave would be considered a harsh response unless the conduct is extremely serious (for example, gross misconduct or a safety-critical workplace issue). More commonly, a pattern of repeated or prolonged unauthorised absences, combined with failure to improve after warnings, may justify dismissal.
This is why it’s vital to follow your disciplinary policy and ensure that:
- The rules about absence are clear in writing (ideally in your contract, employee handbook or absence policy)
- You have evidence that warnings (verbal or written) were given before moving to dismissal
- You’ve kept good records of all correspondence and actions taken

Can You Be Sacked Without A Written Warning In The UK?
A common question from both employees and employers is whether it’s possible to be dismissed (“sacked”) without any written warning. In the UK, the general rule is that an employee with over two years’ service should not be dismissed for misconduct (including unauthorised absence) without being given at least one formal warning and the opportunity to improve.
There are exceptions for gross misconduct - very serious breaches like theft, violence, or gross negligence - but unauthorised absence will usually need to follow the fair use and disciplinary process outlined above.
If you dismiss someone without warning for a less serious absence, you risk an unfair dismissal claim. These claims can be both costly and damaging to your business’s reputation, so a cautious, process-driven approach is always recommended.
What Documentation Should Employers Keep?
Good record-keeping is essential when handling unauthorised absences or any disciplinary matter. Make sure to keep copies of:
- Staff contracts, policies, and handbooks (with clauses about absence, misconduct, and disciplinary procedure)
- All correspondence with the employee about their absence (including attempts to contact them)
- Records of verbal and written warnings, with dates and details
- Notes of all disciplinary meetings or hearings
- Any evidence provided by the employee explaining their absence
- The final outcome and basis for any decision to dismiss
Clear documentation can make the difference between a successful defence and a costly tribunal loss if a dispute arises later.

Legal Risks of Getting It Wrong
If you dismiss an employee for unauthorised absence without a proper process, several legal risks arise, including:
- Unfair Dismissal Claims: Employees with at least two years’ service who are dismissed in breach of fair process can bring a tribunal claim, potentially leading to compensation being awarded.
- Discrimination Claims: If the absence relates to a protected characteristic (e.g. disability, pregnancy, mental health), or insufficient allowance was made for reasonable adjustments, you could face a discrimination case under the Equality Act 2010.
- Wrongful Dismissal: If the contract or policy is not followed, or pay is withheld without a valid reason, employees may have a claim for breach of contract.
For peace of mind, it’s always best to seek help from an employment law expert before taking any drastic steps with an employee.

Best Practice Tips For Managing Unauthorised Absence
Preventing problems is always the best strategy. Here’s how you can handle unauthorised absences effectively:
- Have A Clear Absence Policy: Spell out exactly what counts as authorised and unauthorised absence, who to notify, and the consequences of not following the policy.
- Communicate Expectations: Regularly remind your staff of the rules regarding attendance, absence notification, and what happens if they don’t comply.
- Be Consistent: Apply your policies fairly to all staff to avoid complaints of unfair treatment or discrimination.
- Offer Support: Sometimes absences are linked to health, family, or workplace issues. Show support and signpost to relevant help where appropriate - it’s both good practice and helps keep morale up.
- Document Everything: Keep written notes of all communications, meetings, and warnings.
- Seek Professional Advice Early: If in doubt about any step in the disciplinary or dismissal process, get advice. Early involvement of legal experts can prevent missteps and protect your business.
