Unplanned absences are employee absences that were not scheduled in advance — sick leave, family emergencies, and unexpected personal issues. They are the most disruptive type of absence because they occur without warning, leave gaps in coverage, and require immediate management response. Handling them well means having clear procedures that everyone follows, so the manager is not making up the process as they go.

This guide covers how to handle unplanned absences effectively — from the notification procedure through to the return-to-work process.

Key Takeaways

  • Clear reporting procedures reduce disruption — every employee must know exactly what to do when they cannot work.
  • Same-day notification is essential — employees should report absence by the start of the working day.
  • Fit notes are required after seven consecutive days of sickness absence.
  • Return-to-work interviews should follow every unplanned absence of one day or more.
  • Patterns of unplanned absence should be investigated — not all absences are genuine sickness.

Step 1: Define the notification procedure

Every employee must know exactly what to do when they cannot work:

Who to notify

  • The direct line manager is the primary contact.
  • If the manager is unavailable, a designated backup (team lead or department head).
  • Notify via the agreed channel — phone call, Slack message, Teams message, or text.

When to notify

  • By the start of the working day or as close to it as possible.
  • For the first day of absence, notification should be immediate.
  • For subsequent days, the employee should update the manager daily (or as agreed).

What to provide

  • The reason for absence (they do not need to provide a diagnosis).
  • The expected duration — even a rough estimate helps with planning.
  • Any handover of critical tasks (the employee should arrange this before going off, if possible).

What NOT to require

  • A fit note for absences of seven days or fewer. The NHS does not issue fit notes for short absences.
  • A diagnosis — the reason for absence is sufficient; the specific condition is personal data.
  • Evidence for every absence — trust the employee unless there is a pattern.

Step 2: Log the absence

The absence must be recorded immediately:

  1. Manager logs the absence in the leave management system.
  2. Leave type is recorded as sick leave (or unplanned absence).
  3. Dates are noted — start date and expected duration.
  4. Fit note date is noted if applicable (after day 7).
  5. Team calendar is updated to reflect the absence.

Do not wait for the employee to return before logging. Record on the day.

Step 3: Arrange cover

The manager’s job during an unplanned absence is to maintain team operations:

  1. Identify critical tasks the absent employee owns.
  2. Redistribute tasks to available team members.
  3. Notify stakeholders if deadlines will be affected.
  4. Consider temporary cover for absences expected to last more than a week.
  5. Do not wait — cover should be arranged on the first day of absence.

Step 4: Monitor the absence

For absences that extend beyond a day or two:

Short-term absence (1–7 days)

  • Daily or every-other-day check-in with the employee.
  • Ask how they are feeling and whether they expect to return on the expected date.
  • Do not pressure them to return before they are ready.

Extended absence (7+ days)

  • Request a fit note from the employee’s GP.
  • Consider an occupational health referral if the absence is likely to last more than 4 weeks.
  • Discuss a phased return or reasonable adjustments with the employee.

Long-term absence (4+ weeks)

  • Occupational health assessment to understand the condition and expected return date.
  • Regular (monthly) contact with the employee — maintain the relationship.
  • Discuss any reasonable adjustments that could facilitate an earlier return.

Step 5: Conduct the return-to-work interview

On the employee’s first day back, the manager conducts a return-to-work interview:

  1. Ask open-ended questions:
    • “How are you feeling?”
    • “Is there anything we need to know?”
    • “Do you need any adjustments or support?”
  2. Document the return in the leave management system.
  3. Confirm the employee is fit to resume their duties.
  4. Discuss any follow-up actions — referrals, adjustments, modified duties.
  5. Keep it supportive — the tone is care, not interrogation.

The return-to-work interview is the single most effective tool for reducing future unplanned absence.

Step 6: Address patterns

If unplanned absences form a pattern — Monday/Friday absences, frequent one-day absences, absences around holidays — investigate:

  1. Check the Bradford Factor — is the pattern statistically significant?
  2. Conduct a return-to-work interview with open-ended questions.
  3. Refer to occupational health if a medical cause is suspected.
  4. Start the formal absence management process if the pattern continues without explanation.
  5. Do not accuse — gather evidence and follow the process.

Common unplanned absence handling mistakes

1. No notification procedure

If there is no clear procedure, employees improvise — some call, some text, some email, some do nothing. A clear procedure eliminates this.

2. Not logging the absence

If the absence is not recorded, it does not exist in the system. This creates problems for payroll, reporting, and absence pattern analysis.

3. Waiting to arrange cover

Cover should be arranged on the first day. Waiting until the absence extends to arrange cover leaves the team exposed.

4. No return-to-work interview

The return-to-work interview takes 10 minutes and prevents future absence. Skipping it sends the message that absence is not noticed.

5. Over-reacting to a single absence

A single day off is not a problem. Patterns are a problem. Do not treat every absence as suspicious.

Putting it into practice

Five checks cover most unplanned absence handling:

  1. Define and communicate a clear notification procedure — who, when, how, and what.
  2. Log the absence on the day it occurs and update the team calendar immediately.
  3. Arrange cover for critical tasks from day one.
  4. Conduct a return-to-work interview on the first day back.
  5. Monitor patterns using the Bradford Factor and address them through the formal process.

A leave management system that logs unplanned absences in real time, prompts return-to-work interviews, tracks patterns, and calculates Bradford Factor scores makes handling unplanned absences consistent and proactive.

Frequently Asked Questions

How should employees report an unplanned absence?

The employee should notify their direct line manager by the start of the working day through the agreed channel (phone, Slack, or Teams). They should provide the reason and expected duration.

When is a fit note required?

A fit note is required after seven consecutive days of sickness absence. For absences of seven days or fewer, no fit note is needed.

What is a return-to-work interview?

A brief conversation between the manager and employee on the employee’s first day back from absence. It covers how the employee is feeling, whether they need support, and any follow-up actions.

How do you handle frequent one-day absences?

Use the Bradford Factor to identify patterns, conduct return-to-work interviews, and investigate root causes. If the pattern continues without explanation, follow the formal absence management process.

Should managers check on absent employees?

Yes. Regular check-ins (daily or every other day) show the employee they are valued and help the manager plan for their return. The tone should be supportive, not pressuring.
