How To Properly Document And Manage Employee Sick Leave
Consistent, well-documented absence management protects both employees and employers. This guide outlines how to record, communicate, and respond to sickness absence — including when a fit note or supporting medical letter is needed.
Consistent recording
Log all absences — including dates, stated reason, and any medical documentation received. Consistency reduces the risk of discrimination claims and supports fair decision-making.
Return-to-work conversations
A brief, structured conversation when an employee returns from any absence is one of the most effective tools for managing short-term sick leave and identifying underlying issues early.
Sensitive handling
Absence related to mental health issues requires a particularly careful approach. Create a culture where employees feel able to discuss difficulties without fear of judgment.
A Practical Absence Management Process
Record and track absences systematically
Use a consistent system — even a simple spreadsheet — to record absence start and return dates, stated reasons, and any documentation provided. The NHS Employers sickness absence toolkit provides useful frameworks adaptable to most organisations.
Know when to request a fit note
Employees are entitled to self-certify for up to seven calendar days. A fit note from their doctor is required from day eight onwards, unless your policy requests documentation earlier. Any early documentation must be obtained through a clinically appropriate channel.
Consider adjustments and support options
For employees with recurring or long-term health conditions, consider whether necessary adjustments are required under the Equality Act. Access to employee assistance programmes can also provide early support and reduce the duration of absence.
Clinical Review & Documentation
When an employee needs a fit note or supporting medical letter, any documentation issued through our service is reviewed by a GMC-registered UK doctor. Certificates are not automatically generated — clinical judgement is applied in every case.
- Reviewed by GMC-registered UK doctors following clinical assessment
- Not automatically approved — may be declined where clinically unsupported
- Handles data in accordance with data protection laws like GDPR
- Suitable for employer submission where eligibility criteria are met
Limitations & When In-Person Care Is Needed
- Online documentation is not a substitute for occupational health assessment in complex or long-term cases.
- If an employee reports a serious deterioration in health — physical or mental — they should contact their GP, NHS 111, or 999 in an emergency without delay.
- Decisions about adjustments and capability processes should always involve HR and, where appropriate, employment law advice — particularly where a disability may be involved.
- Final decisions on medical certificates rest with the clinician, not with the employer or employee.
Frequently Asked Questions
How long should absence records be kept?
Under UK GDPR and data protection principles, personal health data should be retained only for as long as necessary for the purpose for which it was collected. Many employers retain absence records for the duration of employment and a defined period thereafter — typically two to five years. Records containing sensitive health data require appropriate security and access controls.
Can absence records be used in disciplinary proceedings?
Yes, documented absence records are central to any capability or attendance management process. Without consistent records, employers face difficulty justifying any formal action. However, records relating to a disability-related condition must be handled with particular care to avoid discrimination claims under the Equality Act 2010.
What should a return-to-work form include?
A return-to-work form typically captures the dates of absence, the stated reason, whether a fit note was provided, and any support or adjustments discussed. It should be completed by the employee and line manager together, and held securely as a confidential HR record.
Does the employer have to accept any fit note at face value?
Employers are generally expected to take fit notes at face value unless there is clear reason to doubt them. However, they may seek further medical information — via occupational health or with the employee’s consent from their GP — particularly for long-term or recurring absences.
What is a Bradford Factor score and is it useful?
The Bradford Factor is a formula used to highlight frequent short-term absences, giving greater weight to multiple short spells than a single long absence. It can help identify patterns but should not be used mechanically. It is important to investigate the reasons behind absence before taking any formal action, particularly where an underlying health condition may be a factor.
Can an employer require medical evidence for every absence?
Employers can set policies requiring documentation earlier than the statutory seven-day threshold, but must apply these consistently and consider the cost and practicality for employees. Requiring a doctor’s note for every single day off could, in some circumstances, be considered unreasonable or potentially discriminatory.
Need a Fit Note or Medical Letter?
Our service connects you with GMC-registered UK doctors for clinical assessment — supporting employer documentation needs where eligibility criteria are met.
