A return-to-work letter after sickness absence serves two purposes: it welcomes the employee back and documents the absence for HR records. For UK employers, a structured return-to-work process — backed by a written record — helps identify underlying health issues, reduce repeat absence, and demonstrate that you are meeting your duty of care under the Health and Safety at Work etc. Act 1974.
Key Takeaways
- A return-to-work letter should be sent after the absence is concluded, not before the employee returns.
- Short-term absence (1-7 days) requires a brief check-in letter. Long-term absence requires a structured return plan.
- UK employers may require a fit note for absences over seven calendar days — but cannot require one for shorter absences.
- A return-to-work meeting is not legally mandated, but it is ACAS best practice and reduces the risk of Employment Tribunal claims.
- For pregnancy-related or disability-related sickness, additional protections apply under the Equality Act 2010.
Template 1: Return After Short-Term Sickness (1-7 Days)
For brief absences — a simple welcome-back and informal check-in.
Subject: Welcome Back — Return to Work After Sickness
Dear [Employee Name],
Welcome back. I hope you're feeling better.
Following your absence from [Start Date] to [End Date], I'd like to schedule a brief 10-minute catch-up to check in and make sure everything is in order. Let me know when suits you today or tomorrow.
No need to prepare anything — this is just a quick touch-base.
Best regards,
[Your Name]The informal check-in is not a formal investigation. Its purpose is to confirm the employee is fit to work and to identify any adjustments they might need.
Template 2: Return After Extended Sickness (Over 7 Days)
Longer absences warrant a more structured approach, especially if a fit note was provided.
Subject: Return to Work — [Employee Name] — Plan and Meeting
Dear [Employee Name],
Welcome back. I hope your recovery is progressing well.
As your absence exceeded seven calendar days, I'd like to schedule a return-to-work meeting to discuss:
- How you are feeling and whether you need any adjustments
- The current status of your duties and any catch-up needed
- Whether a phased return or reduced hours would be appropriate
The meeting will take about 30 minutes. Please bring any fit notes or medical evidence if you have them. You are welcome to be accompanied by a colleague or trade union representative.
We can schedule the meeting for [Date and Time]. Let me know if that works or if you'd prefer an alternative.
Best regards,
[Your Name]A structured return-to-work meeting after extended sickness is ACAS recommended practice. It ensures the employer is meeting its duty of care and provides an opportunity to discuss reasonable adjustments under the Equality Act 2010.
Template 3: Phased Return Plan Letter
For employees returning from significant illness or surgery, a phased return — gradually increasing hours or duties — can be structured with a written plan.
Subject: Phased Return to Work Plan — [Employee Name]
Dear [Employee Name],
Following our return-to-work meeting on [Date], I'm writing to confirm the phased return plan we agreed.
**Week 1 ([Start Date] — [End Date]):** [X] hours per day, [Y] days per week, desk-based duties only
**Week 2 ([Start Date] — [End Date]):** [X] hours per day, [Y] days per week, light duties
**Week 3 ([Start Date] — [End Date]):** Full hours, reduced duties
**Week 4 onwards:** Full duties (review point)
We will review progress at the end of each week. If at any point the plan feels too demanding, please speak to me and we will adjust it.
You will be paid at your normal rate throughout the phased return period.
Please confirm that you are happy with this plan. If you would like any changes, let me know.
Best regards,
[Your Name]A phased return is not a legal right in the UK, but it is a common reasonable adjustment under the Equality Act 2010. Employees should be paid at their normal rate during a phased return unless the contract states otherwise.
Template 4: Return-to-Work Meeting Summary (Formal Record)
After the meeting, document the discussion and any agreed actions.
Subject: Return-to-Work Meeting Summary — [Employee Name] — [Date]
Dear [Employee Name],
Thank you for meeting with me today to discuss your return to work. This email summarises what we discussed and any agreed actions.
**Absence period:** [Start Date] to [End Date]
**Reason given:** [Brief summary, as discussed]
**Points discussed:**
- Current health and fitness to work
- Any adjustments or support needed
- Work catch-up plan
**Agreed actions:**
- [Action item, owner, deadline]
- [Action item, owner, deadline]
**Next steps:**
- Next check-in scheduled for [Date]
- Return to full duties from [Date]
If anything in this summary is incorrect, please let me know.
Best regards,
[Your Name]This record is important for tracking absence patterns. If the employee has frequent short-term absences, the Bradford Factor can help identify whether a formal absence management process is needed.
Template 5: Letter Requesting Occupational Health Referral
For recurring or complex health issues, an occupational health assessment provides medical guidance.
Subject: Occupational Health Referral — [Employee Name]
Dear [Employee Name],
Following your recent absence, we believe an occupational health assessment would help us understand how best to support your return to work and ongoing health.
We have arranged a referral to [Occupational Health Provider]. The appointment is scheduled for [Date and Time] and will last approximately [duration]. You can attend during working hours, and the cost will be covered by the company.
The assessment will provide recommendations on:
- Your fitness to carry out your role
- Any adjustments that may help you at work
- A likely return-to-work timeframe
Please let me know if you have any questions about the process.
Best regards,
[Your Name]For more detail on the occupational health referral process, see our occupational health referral template.
Legal Context for UK Employers
Under the Health and Safety at Work etc. Act 1974, employers have a duty to ensure the health, safety, and welfare of employees. A return-to-work process supports this duty by identifying workplace factors that may be contributing to absence. Under the Equality Act 2010, employers must make reasonable adjustments for employees with disabilities — a return-to-work meeting is the natural place to identify whether adjustments are needed.
The Management of Health and Safety at Work Regulations 1999 also require employers to conduct risk assessments that cover individual health needs. A return-to-work process feeds into this obligation.
Important: If the absence is pregnancy-related, additional protections apply. See our guide on maternity and paternity leave in the UK for context.
FAQ
Is a return-to-work meeting mandatory in the UK?
No, but it is ACAS best practice. Many employers make it a contractual requirement as part of their absence management policy. Without one, it is harder to identify underlying issues or defend absence-related decisions at tribunal.
Can an employee refuse to attend a return-to-work meeting?
They can refuse, but this may be treated as a failure to follow a reasonable management instruction. The meeting should be framed as supportive rather than punitive to encourage participation. See our absence management guide for best practices.
What should I do if the employee is not fit to return?
Do not allow them to return to work if they are unfit. Consider extended sick leave, a phased return, or occupational health referral. Allowing an unfit employee to work could breach your duty of care.
How long should a phased return last?
There is no set limit. Common durations are 2-6 weeks. The plan should be reviewed regularly and adjusted based on medical advice and the employee’s feedback.
Do I need a doctor’s note for a return-to-work meeting?
No. For absences over seven days, you may have a fit note on file, but the meeting itself does not require any medical evidence. The fit note will have informed your understanding of the employee’s fitness to work.
