Absence measurement and management

Organisations need effective people management policies to promote engagement and attendance and therefore keep sickness absence at an appropriate and manageable level. Employees need well-defined job roles, challenging but realistic targets, and support and training to help them achieve these targets. Creating a good work environment means employees are less likely to wake up and think ‘I don’t feel like going in to work today’.

Effective absence management is also about supporting employees with health problems to stay in or return to work. Developing effective return-to-work programmes and offering flexible working where possible form part of an effective attendance management strategy. A focus on employee well-being and health promotion can help avoid non-genuine absence problems developing. Employers should remember that most absence is genuine and that employees often need support in their recovery from illness.

Employee absence is a significant cost to businesses. Our Health and well-being at work survey has data on sickness absence levels and causes . It also looks at current practices in managing absence and attendance. While it’s been reported that sickness absence is at its lowest rate since records began, the same official statistics suggest challenges ahead among older and part-time workers. As the workforce ages, people are more likely to develop long-term health conditions and/or disabilities and so it’s important that employers develop supportive workplaces that help people to manage their health and work.

Fostering employee well-being is good for people and their employers. Promoting well-being can prevent problems from escalating and help create positive working environments where individuals and organisations can thrive.

Effective attendance management involves finding a balance between providing support to help employees with health conditions stay in and return to work, and taking consistent and firm action against the minority of employees who may try to take advantage of organisations’ occupational sick pay schemes.

Types of absence

There are many reasons why people take time off work:

• short- or long-term sickness 
• other authorised absences, including annual leave; maternity, paternity, adoption, or parental leave; time off for public or trade union duties, or to care for dependents; compassionate leave; educational leave
• unauthorised absence or persistent lateness.

This factsheet focuses on sickness absence issues. For more information on authorised forms of absence, see our working hours and time off work factsheet.

In our annual survey, the main causes of sickness absence have been identified as:

• minor illness (includes colds/flu, stomach upsets, headaches and migraines)
• stress
• musculoskeletal injuries, including back pain
• home/family/carer responsibilities
• mental ill health (for example depression and anxiety).

Accurate measurement and monitoring, identifying trends and exploring the underlying causes are key elements in effective absence management.

There are different ways of measuring time lost:

‘Lost time’ rate

This measure expresses the percentage of total time available which has been lost due to absence. It can be calculated separately for different departments to identify areas of concern.

Total absence (hours or days) in the period x 100
Possible total (hours or days) in the period

Frequency rate

This measure shows the average number of absences per employee expressed as a percentage. It gives no indication of the length of each absence period or any indication of employees who take more than one spell of absence.

No of spells of absence in the period x 100
No of employees

The calculation gives an individual frequency rate by counting the number of employees who take at least one spell of absence in the period, rather than the total number of spells of absence.

Bradford Factor

By measuring the number of spells of absence, the Bradford Factor identifies persistent short-term absence for individuals and is therefore a useful measure of the disruption caused by this type of absence. It's calculated using the formula:

S x S x D

where S = number of spells of absence in 52 weeks taken by an individual
and D = number of days of absence in 52 weeks taken by that individual.

For example:

10 one-day absences: 10 x 10 x 10 = 1,000
1 ten-day absence: 1 x 1 x 10 = 10

5 two-day absences: 5 x 5 x 10 = 250
2 five-day absences: 2 x 2 x 10 = 40

It should be noted that the use of Bradford Factor scoring can be controversial and care should be taken when using this as a guide to identify issues with an employee’s absence record. The Bradford Factor can unfairly penalise employees who fall ill and then come back to work as quickly as possible. The reasons for an employee taking frequent periods of absence should be discussed with the employee before any disciplinary action is taken. The Equality Act 2010 ensures that processes and procedures related to absence are adjusted for employees with a disability. A person’s disability may predispose them to regular short-term absences, and this could potentially lead to tribunal action if the employee was unfairly disciplined as a result of receiving a high Bradford Factor score.

Organisations should have a clear policy that supports their business objectives and culture, and explains the rights and obligations of employees when absent due to sickness. The law requires employers to provide staff with information on any terms and conditions relating to incapacity for work due to sickness or injury, including any provision for sick pay.

The policy should:

• provide details of contractual sick pay terms and their relationship with statutory sick pay
• explain when and who employees should notify if they are not able to attend work
• include when (after how many days) employees need to fill in a self-certificate form
• contain details of when employees need to provide a fit note from their doctor
• say that the organisation reserves the right to require employees to attend an examination by a company doctor and (with the individual's consent) to request a report from the employee’s doctor
• include provisions for return-to-work interviews
• explain that adjustments may be appropriate to assist the employee in returning to work as soon as is practicable
• give guidance on absence during major or adverse events (for example, snow, pandemics or popular sporting events such as the Olympic Games or World Cup).

Fit notes

In April 2010, the ‘fit note’ replaced the ‘sick note’, though the system is being reviewed – read the blog Is the fit note fit for purpose?

When completing a fit note a doctor has the choice between two options:

• not fit for work
• may be fit for work.

If the doctor selects ‘may be fit for work’, one of the following four options also has to be selected:

• phased return to work
• amended duties
• altered hours
• workplace adaptations.

The doctor then has the option to make any additional comments.

Employers should arrange to meet with an employee who is assessed as ‘may be fit for work’ to discuss appropriate ways to manage the return to work process and support the employee by making adjustment.

Absence interventions

Effective interventions in managing short-term absence include:

• return-to-work interviews
• use of trigger mechanisms such as the Bradford Factor to review attendance
• disciplinary procedures for unacceptable absence levels
• restricting sick pay
• giving sickness absence information to line managers
• involving trained line managers in absence management
• involving occupational health professionals
• providing leave for family circumstances
• offering flexible working.

Return-to-work interviews can help identify short-term absence problems at an early stage. They also provide managers with an opportunity to start a dialogue about any underlying issues which might be causing the absence.

Disciplinary procedures for unacceptable absence should make it clear to staff that unjustified absence will not be tolerated and that absence policies will be enforced.

Promoting a positive attendance culture, while emphasising that genuine sickness absence will be supported, can help to ensure illegitimate absence is not tolerated and attendance-focused initiatives are supported.

The role of line managers

Line managers have an important role to play in managing absence, and our research shows that managers take primary responsibility for managing short-term absence in two-thirds of organisations. However, only around half organisations train their line managers in the skills needed to do this effectively, Managers need good communication skills and the ability to create a trusting culture where employees feel able to flag issues at an early stage. If line managers can spot the early warning signs of potential problems, employees can be given appropriate support before matters escalate.

Line managers need to be trained in:

• the organisation’s absence policies and procedures
• their role in the attendance management process
• the way fit notes operate and how to act upon any advice given by the doctor
• the legal and disciplinary aspects of absence, including potential disability discrimination issues
• maintaining absence record-keeping and understanding facts and figures on absence
• the role of occupational health services and proactive measures to support staff health and wellbeing
• the management of complex cases, in particular 'myth-busting' about what they can, and cannot, do
• the operation (where applicable) of trigger points
• the development of return-to-work interview skills
• the capabilities and confidence needed to raise and discuss potential issues, including those related to more complex or sensitive problems.

Long-term absence is usually defined as lasting at least four week, and can be challenging to manage as the longer someone is off sick, the harder it can be for them to return. Consequently, organisations need to keep in touch with absent employees in a sensitive way and have a formal return to work strategy for those returning after prolonged absence. Awareness of potential disability discrimination issues is also crucial, and organisations should have a disability leave policy that treats absence linked to someone’s disability as distinct from sickness absence.

The role of the line manager is vital in managing long-term absence, but other interventions are also important. These include:

• return-to-work interviews that are supportive and discuss ongoing adjustments where needed
• occupational health (OH) involvement and proactive measures to support staff health and well-being
• a supportive case management approach, for example involving HR/OH/line manager
• risk assessment to help return to work after long-term absence
• changes to work patterns or environment, including flexible working
• return-to-work interviews.

There are five typical elements in the recovery and return-to-work process:

• keeping in contact with sick employees to help prevent them feeling isolated
• planning and implementing workplace adjustments in collaboration with the individual
• accessing professional advice and treatment
• planning and co-ordinating a return-to-work plan
• regular evaluation with the employee about how things are working.

Our Manager support for return to work following long-term sickness absence guidance and checklist looks at the key behaviours managers need to support successful and lasting returns to work after long-term absence.

Used properly, the Acas Code of practice on disciplinary and grievance procedures, together with the employer’s own procedures, provide the main tools for addressing unacceptable absence. See more in our discipline and grievances at work factsheet.

Disability discrimination

Employers may need to make ‘reasonable adjustments’ to support employees who become disabled before they can return to their job, as dictated by the disability discrimination provisions of the Equality Act 2010. Employers should be aware that physical and mental health conditions might be covered under this legislation. For more on how to address the issues, see our factsheets on disability, stress and mental health in the workplace.

Other legislation affecting absence management

If an employer requests a medical report from a health professional, it's essential to follow the Access to Medical Records Act 1998.

Employers must be careful not to breach the Data Protection Act 2018 (DPA) when they collect, use and store information about their employees’ absence. Details of an employee’s health, either physical or mental, are categorised as ‘sensitive personal data’ under the DPA. Read our data protection factsheet.
