Absenteeism is not just about working people calling in sick. Regular or unplanned absence can have significant impact and consequences such as disruption to work schedules, increased pressure, reduced productivity, delay to projects, lower levels of customer service and higher operating costs. For small and medium enterprises (SMEs), this is even more critical as one person's absence will affect the rest of the team.
What HR decision-makers want is not "less absence days", but "better absence days". An intention to gain understanding of the reason for absence, an ability to compare valid or necessary leave and preventable absence, an environment which creates a win–win situation between the demand to attend and caring for the employees.
Absence is when an employee is not present at their place of work when they are expected to be there, especially when it occurs with some regularity, unpredictably or without a valid reason. Leave is a period of scheduled leave that is agreed upon in advance.
A worker might not be at work due to, being sick, an emergency, family issues, transportation delays, stress at work or some other issue. Not every absence is a problem with performance. Planned leave, agreed in advance, can often be built into rotas. Ad hoc leave, or unplanned leave, doesn't work as cover may have to be arranged at short notice.
A readily available attendance policy should state: how employees must notify their absences, when documentation is necessary, how managers should react and what the next steps are should concerns persist.

The distinction matters because treating every type of leave as absenteeism can produce inaccurate HR data and unfair conclusions.
Cost of absenteeism in dollars Not just about wages for days absent when calculating the cost of absenteeism, it costs companies more than just wages for days absent. A number of other direct costs include overtime, replacement costs, lost productivity, managers' time, work delays, and lost productivity for other employees.
A simple calculation is:
Direct absenteeism cost = Number of absence days × Daily employee cost
Suppose an employee earns ?30,000 per month and works approximately 22 days per month.
Daily employee cost = ?30,000 ÷ 22 = ?1,364
If the employee misses 8 working days:
Direct absence cost = ?1,364 × 8 = ?10,912
The real cost may be higher. Suppose the company also spends ?4,000 on overtime or temporary cover, loses an estimated ?5,000 in productivity, and spends ?1,500 on administrative and coordination work.
Estimated total cost = ?10,912 + ?4,000 + ?5,000 + ?1,500 = ?21,412
This is a management approximation, as opposed to a universal accounting formula. Each company should specify assumptions and use the same rule each time.
Staff who are at work may also be impacted by absenteeism. Co-workers could shoulder more work, put in longer hours, and leave their work until another time if an individual misses a day of work. The turmoil of the situation can lead to employee burnout.
There may be many reasons for absences, rather than one overarching one. Typical problems are ill health, stress, burnout, family commitments, transport, pressure of work, management issues, culture and lack of engagement. HR should pin down the root cause before determining the response required.
Perhaps the most obvious reason for absenteeism is genuine illness. It can be caused by any kind of ailment, whether short-term or chronic.
The CIPD Health and Wellbeing at Work survey offers relevant evidence on the extent of sickness absence. In the 2025 survey, the average number of days of sickness absence per employee per year in the survey organisations was 9.4.
This should be considered as the average for the survey, rather than the 'rate' for each country, firm or institute.
Employee burnout may occur when employees experience prolonged heavy workloads, insufficient downtime, tight deadlines, and/or a lack of support.
Exhaustion, declining level of concentration, demoralization, fatigue, and inevitable absence are as a result of Burnout.
High absence should be examined to see if it is related to workload or resourcing issues. A whole team where the absence goes up could suggest an organisational problem.
Late arrivals and absences are often caused by lengthy commutes, delays, congestion, poor transportation and challenging hours.
This might also be the case where, for example, fixed shifts are worked by employees in large cities. If absenteeism is concentrated around particular shifts, HR should determine whether the reason is a scheduling or transport issue.
If staff do not believe their leave requests will be looked upon favourably, they might not feel comfortable raising real issues.
Simultaneously, they can leave the couple in this way: difficulty handling frequent, unexplained absences.
Separately, Gallup's engagement research has identified a correlation between engagement and absenteeism. Its workplace research has identified much lower absenteeism among high-engagement teams compared to low-engagement teams. But this is a correlation across business units, and does not show a causal relationship whereby engagement drives (or does not drive) absenteeism.
This rate indicates the number of hours of scheduled working time lost due to absenteeism. Bradford factor calculates both individual absence frequency and length of time absent. Combining the two measures can be useful for HR in providing insights into workplace trends and recurring short-term absence.
The basic absenteeism rate formula is:
Absenteeism Rate = Total Absence Days ÷ Total Scheduled Working Days × 100
For example, suppose an organization has 50 employees, 22 working days per month, 1,100 scheduled employee-days, and 33 absence days.
33 ÷ 1,100 × 100 = 3%
The company's absenteeism rate is therefore 3% for that period.
For example, the U.S. Bureau of Labor Statistics (BLS) indicated a 3.2% absence rate for wage and salary full-time workers in 2025. Because BLS's measurement and population are defined for this specific measure, don't consider it a guide or benchmark for your population.
Everyone in your HR department should determine your rate every month in a similar manner and compare it to past months. You will be able to see if your attendance rate is getting higher or lower.
The Bradford Factor is designed to highlight frequent short-term absence.
Bradford Factor = S² × D
Where:
For example, an employee has four separate absence spells totaling 10 days:
4² × 10 = 160
Another employee has one continuous 10-day absence:
1² × 10 = 10
The absences for both employees are 10 days but the scores are different because the absences are of different frequency.
The Bradford Factor should only be considered as a 'warning' reminder rather than a prescriptive tool. When HR is asked to take action, they should assess the absence cause, circumstances, policies of the company, and other employment requirements.
Reducing absenteeism requires clear expectations, reliable attendance records, employee support, effective management, and regular analysis. The objective should be to reduce avoidable absence without discouraging legitimate leave or pressuring employees to work when they are unwell.
Outline your expectations for attendance, procedures for reporting absences, requirements for documentation, procedures for returning to work and consequences of repeated unexplained absence.
Your staff should be clear on who to report their absence to and how. Making the process quick is important – it keeps things simple and allows HR to keep accurate data.
Note names, date, duration, categories, departments and shift of all your absence records. It is important to record the same categories and departments over time to pick up repeated problems.
Don't just look at days absent in total. Multiple single days of absence can cause as much disruption as one long day.
An interview following the absence can identify if an employee is prepared to come back and if necessary will require support in the office.
If an entire department is absent more, consider staffing, deadlines, overtime, and task assignments, rather than new individual behavior.
Decide how to address attendance issues. Decide how to have attendance conversations, record concerns, and protect confidentiality, and when to escalate attendance issues to HR.
Where the job can support it, flexible schedules, shift exchanges, telework, and temporary accommodations could benefit employees with bona fide personal situations.
Identify the stress point caused by workload, staffing, management or scheduling problems which are causing burnout. Focus on the problem instead of responding to absences.
If problems are localized to specific times of day or work sites, consider the impact of travel problems or shift times.
Incentives may promote good attendance practices, but organizations should make sure the incentives are not contributing to workers coming to work while ill or employees being unable to take necessary leave.
HR should analyze for absence within the company each month, noting absenteeism rates, frequency of absence, departments, work shift, reasons, and estimated costs. Monitor should regularly analyze to find the problem sooner.
Attendance data can reveal patterns that are difficult to identify from individual cases. HR may discover higher absence on particular weekdays, within specific teams, during certain shifts, or at particular locations. These patterns are signals for investigation, not automatic evidence of misconduct.
Common patterns include:
1. Missing either Monday or Friday: Frequent absence on these days could need further examination but do not presume abuse from the outset.
2. Concern in a Department: When a particular department has significantly higher absences, this could be due to workload, staffing, management or workplace concerns.
3. Shift concentration: One specific shift suffers from greater absence possibly due to shift logistics, making it more difficult to attend the shift.
4. Seasonal absence: Some times will have more illness related absence than others.
5. Frequent short-term absenteeism: Reoccurring one to two day absences could be a pattern that warrants further discussion.
6. Extended absence: Greater absence may necessitate return to work planning and support.
The intention of looking at these trends is to pose questions for HR to examine. The data from attendance should be used as a tool to help in decision making not to be the deciding factor.
Escalation may be appropriate when attendance concerns continue despite clear expectations, appropriate support, and documented discussions. HR should distinguish genuine health or personal circumstances from avoidable or unexplained absence and follow the organization's attendance policy before considering formal action.
A practical process can include six stages.
1. Identify the pattern: Check attendance records and confirm that the information is accurate.
2. Hold a private discussion: Give the employee an opportunity to explain the circumstances behind the attendance pattern.
3. Provide appropriate support: Depending on the situation, this may include workload changes, flexibility, reasonable adjustments, or other appropriate assistance.
4. Set clear expectations: Explain required attendance standards, reporting procedures, and expected improvement.
5. Document discussions: Maintain objective records of relevant conversations, agreed actions, and follow-up dates.
6. Consider formal action: If the problem continues after appropriate support and policy steps, the organization may consider formal attendance or disciplinary procedures.
For example, it could be a warning letter for absenteeism. Never issue a warning simply because a specified number of days off work has been reached or a Bradford Factor score has been achieved.
The HR should take into account the reason for being absent, the protections available, the previous support, the policies and the employment needs.
It can be used as both a people problem and a business metric. As a first step, HR teams can: work out their absenteeism rate, understand how much it costs their organisation, and look for patterns – by frequency, length, location, shift and cause.
How do I identify the reasons why members of my staff are taking time off? It's not just about trying to lower down the number of absences. You want to find out why absences are happening, and eliminate those that are avoidable and assist with those that are genuine. Leave management software can be used to ease the burden of leave and attendance management by consolidating leave applications, attendance and absence data, and HR workflows in one place for companies that want an automated approach to leave and attendance management.
There is no universal ideal absenteeism rate. Industry, workforce structure, working arrangements, and calculation methods differ. Organizations should establish a consistent internal measurement and compare results with relevant benchmarks where definitions are comparable.
The absenteeism rate formula is Total Absence Days ÷ Total Scheduled Working Days × 100. For example, 33 absence days divided by 1,100 scheduled employee-days produces an absenteeism rate of 3%.
The Bradford Factor measures the frequency and duration of absence using S² × D. S represents separate absence spells, while D represents total absence days. It gives greater weight to frequent short-term absence.
Generally, planned and approved leave should be recorded separately from unplanned absenteeism. Organizations should clearly define absence categories in their attendance policy and follow applicable employment requirements.
SMEs can reduce absenteeism through accurate attendance tracking, clear policies, simple absence reporting, manager training, workload management, employee support, appropriate flexibility, and regular analysis of absence patterns.
