Unplanned absence, staff calling in sick or simply failing to turn up with little or no notice, is one of the most disruptive problems a small or medium-sized business can face. Unlike planned annual leave, it cannot be scheduled around, which makes it far harder to manage cover, protect productivity, and control costs.
According to the CIPD Health and Wellbeing at Work Survey 2025, UK sickness absence has reached its highest level in over fifteen years. SMEs feel this impact more acutely than larger organisations because there is less slack in the team to absorb it. The good news is that businesses can reduce unplanned absence significantly with the right combination of policy, process, and proactive management. This guide sets out practical, fair, and legally sound steps any SME can take.
What Counts as Unplanned Absence, and Why It Costs SMEs So Much
Unplanned absence covers any time an employee is unexpectedly away from work, most commonly short-term sickness, but also emergency leave, late no-shows, and unauthorised absence. It is distinct from planned leave such as holiday or maternity leave, which businesses can prepare for in advance. Good employee absence management treats the two very differently.
The financial impact goes well beyond the missing person's wages. For an SME, a single unplanned absence can mean a manager scrambling to rearrange a rota at short notice, colleagues covering extra workload, deadlines slipping, and in customer-facing roles, a direct hit to service levels. At the time of writing (June 2026), SSP is payable from the first day of sickness for eligible employees, following reforms that took effect on 6 April 2026. The lower earnings limit has also been removed. This means even brief absences now carry an immediate payroll cost, so SMEs should check GOV.UK for the current rules before relying on this figure.
Why Unplanned Absence Is Rising
According to the CIPD's Health and Wellbeing at Work 2025 report, UK employees took an average of 9.4 days of sickness absence in the past year, up from 7.8 days in 2023 and a record high. Understanding what is driving this rise helps SMEs target their response.
Minor illness remains the leading cause
Short, unplanned periods of sickness are still overwhelmingly caused by minor illness such as colds, flu, and stomach upsets, which the CIPD found accounts for 78 percent of short-term absence. These episodes are largely unavoidable, but their cumulative impact can be managed through structured, ongoing monitoring.
Mental health and stress are growing factors
Mental ill health is now the second most common cause of short-term absence and the leading cause of long-term absence. Stress, often linked to workload, caring responsibilities, or financial pressure, also features heavily. For SMEs, this points to wellbeing support, not just attendance policing, as part of any genuine solution.
Why Presenteeism Can Cost More Than Absence
It is tempting to focus solely on reducing unplanned absence, but the CIPD's own research warns against treating low absence figures as a sign of good attendance management on their own. Presenteeism, employees coming into work while genuinely unwell, often goes unmeasured, yet it can be more costly than the absence it appears to prevent.
An unwell employee working at reduced capacity tends to produce more errors, take longer over routine tasks, and risks turning a short illness into a longer one, or passing it on to colleagues. Over time, a workplace culture that quietly discourages staff from taking sick leave when they need it can drive up long-term sickness absence rather than reduce it.
Tracking absence data alongside informal signals, such as a manager noticing a usually reliable employee seeming run down, helps SMEs address the underlying problem rather than just the number of days recorded.
Practical Ways to Reduce Unplanned Absence
There is no single fix for unplanned absence, but a combination of the following measures, applied fairly and uniformly, can make a meaningful difference to attendance levels.
Spot patterns early with sickness trigger points
Setting clear trigger points, for example a defined number of occasions or a Bradford Factor score within a rolling period, allows managers to identify a developing pattern of absence before it becomes entrenched, and to start a supportive conversation early rather than reacting after the fact.
Hold consistent return-to-work interviews
Acas guidance recommends a brief, supportive conversation every time an employee returns from sickness absence, however short. Held regularly, return-to-work interviews help managers understand the cause of absence, identify any support needed, and signal that attendance is noticed without feeling like an interrogation.
Train managers to apply absence policy fairly
Even a well-designed absence policy fails if it is applied differently from one manager to the next. Inconsistent handling, one manager letting a pattern slide while another raises it immediately, is one of the most common reasons absence management breaks down in growing SMEs. A short briefing on trigger points, return-to-work conversations, and when to escalate gives managers the confidence to handle absence the same way across the business.
Build resilience into rota and shift planning
Rotas with no slack mean a single absence creates an immediate crisis. Building in a small buffer, cross-training staff to cover multiple roles, and keeping a clear, up-to-date view of who is available reduces the scramble when someone calls in unexpectedly.
Set a clear, well-communicated absence policy
Employees should know exactly how, who, and by when to notify the business of an absence, what evidence is required, and how absence will be recorded and reviewed. Ambiguity around reporting procedures is one of the most common, and most easily fixed, drivers of patchy absence management.
Support employee wellbeing proactively
Flexible hours, manageable workloads, and an open culture around mental health all help prevent the stress-related and minor-illness absences that make up the bulk of short-term sickness. Simple, low-cost measures such as regular one-to-ones and clear workload planning often have an outsized effect on attendance.
Using Technology to Track and Reduce Unplanned Absence
Trigger points, return-to-work interviews, and rota planning all rely on having accurate, up-to-date absence data to hand. Many SMEs still handle attendance management manually across spreadsheets and paper forms, which makes patterns hard to spot and standards difficult to maintain across a growing team.

Staying Compliant While Managing Absence
Reducing unplanned absence has to be balanced against legal obligations. Absence linked to a disability may be protected under the Equality Act 2010, which means trigger points and disciplinary processes may, depending on the circumstances, need to be adjusted for employees with a relevant disability or underlying health condition. Employers should always consider whether reasonable adjustments are appropriate before taking formal action.
It is also worth keeping policies aligned with current Acas guidance on managing staff absence, and with the rules on Statutory Sick Pay, to ensure both fairness and accuracy in how absence is recorded and paid.
Frequently Asked Questions
What counts as unplanned absence?
Unplanned absence is any time off work that has not been agreed in advance, most commonly short-term sickness, but also emergency leave, late no-shows, or unauthorised absence. It differs from planned leave such as holiday, which is scheduled ahead of time and does not disrupt cover in the same way.
How much does unplanned absence cost a small business?
Costs vary by sector and role, but include wages or sick pay, the cost of arranging cover, lost productivity, and management time spent rearranging schedules. With SSP now payable from the first day of sickness, even brief, frequent absences carry a more immediate payroll cost than before April 2026, making early intervention more valuable.
Can an employer take action over persistent unplanned absence?
Yes, provided the process is fair, consistent, and well documented. Employers can use trigger points to identify a pattern, hold supportive conversations, and move to formal performance or disciplinary procedures if absence does not improve, while always considering whether the absence may be linked to a disability or other protected circumstance under the Equality Act 2010.
What is a reasonable absence rate for an SME to aim for?
There is no single legal benchmark, but the CIPD's 2025 survey found UK employees took an average of 9.4 days of sickness absence per year. Many SMEs use this as a rough benchmark and focus less on hitting an exact number and more on spotting and addressing individual patterns early.
How do return-to-work interviews help reduce absence?
They give managers a regular, low-pressure opportunity to understand the cause of an absence, flag any support the employee might need, and make clear that attendance is being noticed. Acas guidance recommends holding one after every absence, however short, as part of a consistent process rather than an occasional check-in.
Is Bradford Factor scoring legal to use in the UK?
Yes, the Bradford Factor is a widely used and lawful method of monitoring absence patterns, provided it is applied consistently, communicated clearly to staff, and used alongside, not instead of, a fair process that considers individual circumstances such as disability-related absence.
Further Reading and Official Guidance
Conclusion
Unplanned absence will never disappear entirely, minor illness and life's emergencies are unavoidable, but SMEs that combine clear policies, structured return-to-work conversations, early trigger points, and resilient rota planning can reduce its frequency and soften its impact considerably.
The businesses that manage this best are the ones with accurate, accessible absence data and a process they apply fairly and uniformly to every employee. Start by reviewing how absence is currently recorded and reported in your business, and look for the gaps that make patterns hard to spot. If spreadsheets and paper records are slowing that process down, it may be time to explore a dedicated tool built for the job.
