When an employee fails to return from leave on the agreed date, the employer needs to establish the facts, provide a fair process, and document every step. The cause could be as innocent as a missed flight or as serious as deliberate abandonment. UK employers must distinguish between authorised absence extensions (where the employee communicated), failure to return without communication (potential conduct or resignation), and protected leave situations (maternity, parental, disability-related).
Key Takeaways
- Distinguish between types of leave — failure to return from annual leave is managed differently from failure to return from maternity or sick leave.
- Contact the employee immediately — a missed return date may have a simple explanation.
- Never assume the employee has resigned — they are still employed until the process is concluded.
- Employees on statutory maternity, paternity, or shared parental leave have enhanced protection against detriment and dismissal.
- Document every attempt to contact and every conversation — this is critical evidence if the matter reaches an Employment Tribunal.
Template 1: Initial Contact Letter (Day 1-2 After Missed Return)
The first step is always to reach out. The employee may have a legitimate reason.
Subject: Return to Work — [Employee Name]
Dear [Employee Name],
You were due to return to work on [Return Date] following [annual leave / sick leave / maternity leave], but I have not heard from you and you did not attend work as expected.
Please contact me at [Phone Number] or [Email Address] as soon as possible to confirm when you will be returning and whether any support is needed.
If there is a reason for your delay that you have been unable to communicate, let me know so we can discuss it.
We are concerned for your wellbeing and want to hear from you.
Best regards,
[Your Name]Send this letter by both email and recorded delivery. The tone should be concerned, not accusatory — the employee may have been hospitalised, experienced a family emergency, or faced travel disruption.
Template 2: Follow-Up Letter (Day 3-5 With No Response)
Escalate the tone while still leaving the door open for a communication.
Subject: Urgent — Return to Work — [Employee Name]
Dear [Employee Name],
We wrote to you on [Date of first letter] regarding your failure to return to work from [leave type] on [Return Date]. We have not received any response from you despite attempting to reach you by [phone / email / text].
Please be aware that your continued absence without authorisation may result in disciplinary action, up to and including dismissal.
We ask you to contact [Manager Name] by [Date and Time — e.g. 48 hours from this letter] to explain your absence.
If you need support or are facing circumstances that prevent you from contacting us, please let us know and we will do what we can to help.
We remain concerned for your wellbeing and urge you to get in touch.
Yours sincerely,
[Your Name]This letter sets a deadline. If the employee contacts within that deadline, the matter changes from a conduct concern to a conversation about their circumstances.
Template 3: Employee Contacted — Extension Needed (Communication Made)
If the employee reaches out and needs an extension, confirm the terms in writing.
Subject: Confirmation — Extended Leave Arrangement
Dear [Employee Name],
Thank you for contacting us and explaining your situation. This letter confirms our discussion.
You were due to return from [leave type] on [Original Return Date]. We have agreed that your return to work will be extended to [New Return Date].
The following applies to this extension:
- [If annual leave:] This extension will be [paid annual leave / unpaid leave / a combination] in accordance with your leave balance and our policy.
- [If sick leave:] Please provide a fit note covering the extended period if you have not already done so.
- [If maternity leave:] Please let us know if you wish to change your notified return date formally — you may need to give eight weeks' notice under [Employment Rights Act 1996 / Maternity and Parental Leave Regulations 1999].
Please confirm your agreement to this arrangement by return of email.
Best regards,
[Your Name]Different leave types have different extension rules. Annual leave extensions must be agreed. Sick leave usually requires a fit note. Maternity leave changes require formal notice under the Maternity and Parental Leave Regulations 1999.
Template 4: Employee Contacted — No Valid Reason (Formal Investigation)
If the employee contacts but has no valid reason for the delay, proceed with a formal investigation.
Subject: Invitation to Investigation Meeting — Failure to Return From Leave
Dear [Employee Name],
You were due to return to work from [leave type] on [Return Date] but did not do so. You have indicated that [briefly summarise their explanation — or if none, state "you have not provided a reason for your failure to return"].
I am writing to invite you to an investigation meeting to discuss this matter.
The meeting will be held on [Date] at [Time] in [Location]. You have the right to be accompanied by a work colleague or trade union representative.
Please let me know if you require any reasonable adjustments for the meeting.
Yours sincerely,
[Your Name]Template 5: Failure to Return From Maternity Leave (Specific Situation)
Employees on maternity leave have enhanced protection. A failure to return must be handled with particular care.
Subject: Return to Work After Maternity Leave — [Employee Name]
Dear [Employee Name],
Your maternity leave was due to end on [End Date], and you were expected to return to work on [Return Date]. I understand you have not yet returned and would like to discuss this with you.
If you wish to extend your maternity leave or change your return date, please let me know. You may be able to:
- Take additional [annual leave](/blog/annual-leave-during-maternity-leave-uk/) or unpaid leave following your maternity leave
- Change your return date by notifying us in writing (subject to eight weeks' notice if the new date is before the original return date)
- Discuss flexible working or a phased return
Alternatively, if you have decided not to return to work, please let us know so we can discuss the process for [shared parental leave](/blog/shared-parental-leave-uk/) or resignation.
Please contact [HR Contact] at [Phone Number] or [Email Address] to discuss your options.
Best regards,
[Your Name]Maternity leave is protected — an employee cannot be dismissed or disadvantaged simply for not returning on the exact date if they are in communication. Dismissal in connection with pregnancy or maternity is automatically unfair under the Employment Rights Act 1996.
Template 6: Outcome — Dismissal for Failure to Return

[Your Name]Legal Context
The Employment Rights Act 1996 sets out the rights relating to dismissal. An employee who fails to return from leave has not automatically resigned — the employer must go through a fair process before dismissal. The ACAS Code of Practice on Disciplinary and Grievance Procedures applies to any dismissal for failure to return from leave.
For employees returning from maternity leave, the Maternity and Parental Leave Regulations 1999 provide additional protection. An employee who does not return from maternity leave is entitled to her old job back for up to 52 weeks — only after that can alternative employment be considered.
For sickness absence, the Equality Act 2010 may apply if the absence is disability-related. Consider an occupational health referral before taking formal steps.
FAQ
Should I treat failure to return as job abandonment or a disciplinary issue?
In the UK, “job abandonment” is not a formal legal concept as it is in the US. Treat it as a conduct issue through the disciplinary procedure. If the employee has simply stopped communicating, this may constitute gross misconduct.
What if the employee has a medical reason for not returning?
This changes everything. If the employee gives any indication of a medical reason, pause the disciplinary process and consider occupational health referral and reasonable adjustments before proceeding.
Can I force an employee to return from leave early?
Generally no, unless the employment contract contains a specific clause allowing the employer to cancel approved leave (subject to the right notice period). For statutory leave (maternity, paternity, parental), you cannot force an early return under any circumstances.
What notice is required to change a maternity return date?
If the employee wants to return earlier than originally notified, they must give eight weeks’ notice. If they want to extend their maternity leave, they can do so by notifying the employer — the first 52 weeks are protected.
Do I need to hold a hearing before dismissing for failure to return?
Yes. A fair dismissal requires a hearing where the employee has the opportunity to present their case. Even if the employee does not attend, you must still hold the hearing and consider the evidence. See the ACAS guide on disciplinary hearings for the full process.
