Absence management methods: A practical guide for UK HR teams

Absence management methods are the strategies that HR teams use to record time off, reduce absenteeism and respond to employee absences. Popular absence management strategies include absence policies, return to work interviews, flexible working arrangements and occupational health referrals.

Most HR teams use a mix of methods to build a system that aligns with legal requirements and the company’s culture, goals and policies. 

Poor workplace health costs UK businesses a staggering £85 billion per year. While it’s impossible to prevent the impact (and cost) of all absences, introducing the right absence methods can lead to considerable benefits, like: 

• Higher attendance: Find and fix issues faster by tracking leave and identifying patterns, then introduce strategies to support employees and reduce absenteeism in the workplace.

• Increased performance: Introduce policies and perks that allow your teams to take time off and rest — teams can’t perform at their best without breaks.

• Fewer unauthorised absences: Make it easier for everyone to understand and follow rules and processes with clear absence policies. 

• Improved staff morale: Offer more than the minimum that’s legally required and introduce perks that promote employee wellbeing to show employees that they’re cared for.

• Balanced workloads: Plan cover and distribute workloads fairly by having a simple process to follow when someone is away from work unexpectedly. 

• More hiring power: Attract and retain the best talent with generous policies, processes and perks related to work-life balance, time off and employee wellness. 

Absence management might appear simple on paper, but the reality involves more than recording time off — especially with the recent changes introduced by the Employment Rights Act 2025. The main challenges for HR teams include:

• Accurately tracking leave: It’s complicated to record, categories and report on different types of leave — especially in a large business or one without the right software.

• Arranging handovers: Preparing for absence cover can cause stress or disruption for managers and team members, especially if it’s unexpected.

• Dealing with sudden absence: Most absences are unplanned, so they’re hard to plan for and often require you to drop your to-do list to take care of arrangements. 

• Handling issues sensitively: Staff may violate company policies due to difficult personal circumstances, which requires balancing disciplinary action with empathy and understanding.

• Managing policies: Company rules and guidelines need to be thorough enough to cover all types of absence, but simple enough that they’re easy to understand and follow.

• Maintaining compliance: Keeping up to date with employment law changes is part of the job for HR teams, and that includes updating policies, processes and guidance for managers.

HR teams need to be aware of key employment law and how it applies to situations that arise with employees — including Statutory Sick Pay (SSP), fit notes, reasonable adjustments, absence and dismissal.

The rules around Statutory Sick Pay have changed. SSP is now available to all eligible employees (regardless of their earnings) and payable from the first full day of sickness absence — a change from the old model that means more employees can now access support earlier than before. SSP is payable at 80% of the employee’s average weekly earnings or the flat weekly rate, which is currently £123.35 per week.

What this means for employers: Tracking absence accurately is essential, as is triggering the payment of SSP for eligible employees from the first day (in line with the updated legal requirements). 

Employees can self-certify for the first 7 days of absence, but from day 8 they need to provide a fit note. A suitable healthcare professional will complete a fitness for work assessment and state that the employee “may be fit for work” or is “not fit for work”. For employees that “may be fit for work”, employers should consider adaptations to support the employee — like a phased return to work, altered hours, a change in duties or workplace adjustments.

What this means for employers: HR teams need to be aware of the rules around fit notes, when they apply, how to securely keep records and how to introduce adaptations for employees.

Where the underlying reason for an employee's absence constitutes a disability under the Equality Act 2010 (a physical or mental impairment that has a substantial and long-term adverse effect on their ability to carry out normal day-to-day activities), the employer is legally required to consider reasonable adjustments. This means disability-related absence cannot be managed in the same way as general sickness absence — including in trigger-point decisions. 

What this means for employers: HR teams and line managers must be able to recognise when the Equality Act 2010 is likely to apply and seek guidance accordingly.

Persistent absence or long-term absence that renders an employee unable to fulfil their role may, in certain situations, lead to a fair dismissal. This process carries significant legal risk and must follow a fair procedure consistent with the Acas Code of Practice.

What this means for employers: It’s possible to dismiss someone for absence-related concerns, but HR teams should seek specialist employment law advice before attempting any dismissal procedures.

Employee absences all fall into one of four main categories: planned absence, unplanned absence, long-term absence or unauthorised absence. Here’s what each type of absence involves and how HR teams should respond.

Businesses benefit from a clear and easy-to-follow absence management process that sets out the steps, when they happen and who is responsible for every task. A well-documented process protects employees, managers and HR teams from confusion and challenges.

Here’s a sample absence management process: 

1. Employee reports absence: They notify their line manager in line with the absence policy via the agreed channel and within the agreed timeframe. 

2. Line manager acknowledges and records: The manager confirms receipt, notes the reason for absence and expected duration.

3. Absence is logged in the HR system: Line manager or HR records the date, type and stated reason recorded for absence management purposes.

4. Trigger points are monitored: HR identifies when an employee has reached a defined threshold (e.g. Bradford Factor score, number of occurrences within a rolling period) that requires formal review.

5. Return to work interview is conducted: Line manager holds a return to work interview on the employee's first day back to understand the cause, assess wellbeing needs and determine whether any adjustments are required.

6. Data is reviewed periodically: HR analyses absence trends across teams and departments to identify systemic issues.

7. Escalation where warranted: HR makes a referral to occupational health, a formal process, or (as a last resort, after all other options are exhausted) disciplinary action if required.

Effective absence management requires a combination of preventative and reactive methods. While the best approach will depend on your company’s size, sector, workforce composition and culture, most organisations benefit from a mix of these tried-and-true absence management methods.

Create detailed policies that cover all the types of leave so everyone is aware of what the process is and how to follow it. Your policies and processes should be consistent, fair and flexible to individual circumstances, in line with absence policy recommendations from Acas. 

Your absence policies should include:

• Reporting procedures (who to contact, when, and by what method)

• Definitions of acceptable and unacceptable absence

• How absences will be recorded

• Entitlements by absence type

• Details of any absence scoring frameworks used (e.g. Bradford Factor)

• Absence triggers for formal action

• Guidance for employees on their legal rights

Absence policies should also make it clear that employees shouldn’t attempt to or continue working if they’re unwell. Presenteeism costs UK businesses around £21 billion in lost productivity each year, and it’s better for your employees if they fully rest and recover before returning to work. 

Make return to work interviews part of your absence management process. The meeting should be a structured conversation that gives managers an opportunity to:

• Review any guidance from medical professionals (e.g. fit note or health report from doctor)

• Confirm that the employee is ready to return to work

• Provide an update on anything important the employee might have missed (e.g. policy or structure changes, project updates)

• Ask the employee if they would benefit from any further support or reasonable adjustments (e.g. phased return to work or flexible working)

• Consider whether a referral to occupational health or an employee assistance programme is appropriate

• Get a clear understanding of what the employee wishes to share with team members about their absence (or if they wish to keep it confidential)

Effective return to work interviews support better outcomes for employees, act as a deterrent for casual absenteeism and provide HR teams with data they can use to identify patterns across the team or department.

Follow your absence process as it's written as a rule, but leave room for flexibility and line manager judgement in situations with extenuating circumstances. Consider being flexible when the case involves:

• Circumstances beyond the employee’s control (e.g. delays in public transport)

• Moments of intense stress or emotional strain that affected decision making (e.g. witnessing or being involved in an accident)

• Conflicting priorities that caused an employee to take unexpected time off (e.g. sudden illness of a close family member with nobody else to care for them)

Exceptions in policy application are more common for bereavements or family emergencies, but you can also make adjustments for smaller situations too — like an employee that accidentally locks themselves out of their car or mixes up the dates of a booked holiday. 

Flexible working hours allow employees to fit their work schedule around personal obligations, caring commitments and individual needs. As all employees now have the legal right to request flexible working from their first day in a job, it’s sensible to decide on an overall approach to flexibility.

Recent research by CIPD found that:

• 41% of employers believe increased hybrid working has improved productivity and efficiency

• 80% of employees say working flexibly has positively impacted their quality of life

• 3% of workers (representing 1.1 people in total) have left a job in the last year due to a lack of flexible working

A proactive policy with provision for flexible working benefits employees and employers, can prevent unnecessary absence and makes the business more attractive to candidates that prioritise work-life balance and wellness.

Leave workflows minimise the disruption caused by staff absence and help departments plan how to cover an employee’s duties while they’re away. A good absence workflow includes:

• Advance notice: Ask departments to manage holiday requests at least a month in advance so you have time to arrange and prepare cover.

• Task handover: Get a list of all the tasks the employee usually handles (and how to complete the work) so you know what needs to be covered.

• Delegation: Identify which team members (if any) have the expertise and capacity to cover the work, or whether you need to bring in external support.

• Tools and resources: Gather all the necessary materials so they’re ready to hand over.

• Notifications: Ask the employee to set up an out of office autoreply that explains when they’re away, who is handling work in the meantime and how to get in touch with the team.

• Catch up: Plan a meeting with the employee after their period of leave to get them up to speed on what happened while they were away.

It’s not always essential to do a formal handover when the employee returns, but for long-term or unplanned absences it’s helpful to check in and make sure they have the support they need to settle back into their role. 

Support your line managers with the right training, resources and advice so they can not only follow policy guidance but provide thoughtful assistance to employees. 

Line manager training should cover: 

• How to conduct return to work interviews

• How to apply absence policies consistently while exercising judgement

• How to spot the early warning signs of work-related stress or burnout

• When to escalate to HR or occupational health

• How to handle sensitive information in line with data privacy and the Equality Act 2010

Acas recommends manager training as a core way to help reduce sickness absence — the way a line manager handles the situation can directly impact whether the employee feels supported in the workplace or not.

Make it easier for employees to share their opinions, ideas and issues on topics that affect absences — including flexible working, time off policies, employee wellbeing and the introduction of perks and benefits.

Create opportunities for employees to raise concerns and give feedback through:

• Employee surveys

• Suggestion boxes

• Q&A sessions and fireside chats

• Regular 1:1 check-ins with line managers

• Whistleblowing tools

Regular communication supports a culture where employees feel safe raising concerns before they result in absence — especially if concerns can be raised anonymously. 

Invest in software that helps you store and monitor absence data, so you can identify patterns and proactively find ways to prevent future absences. Keep track of key attendance metrics like:

• Total absences

• Absence frequency

• Absenteeism rates

• Average duration of absence

Monitor metrics on a team, department and company-wide level to spot any patterns that might need investigation — like a sudden increase in sickness absence in a chronically understaffed department. 

Some companies rely on the Bradford Factor to alert them to problematic patterns, but leave management software (like Personio) can use more sophisticated analysis to surface trends that aren’t always obvious.

Consider introducing an occupational health service or employee assistance programmes to provide additional support for absence management. 

Occupational health service providers can support in situations where: 

• An employee is struggling with their physical or mental health

• An employee is returning to work after long-term sickness absence

• An employer needs an independent assessment of an employee’s fitness to work

• An employer needs to introduce reasonable adjustments 

• An employer wants advice on reducing sickness absence or managing risks

Employee assistance programmes can support employees with: 

• Short-term counselling

• Bereavement support

• Financial or legal guidance

• Support helplines

While neither are legally required, offering these programmes provides employees and line managers with specific, relevant and timely advice and support in situations they might not have the tools or knowledge to deal with effectively.

Best practices for absence management include having a clear absence policy, consistent manager training, return to work interviews, proactive wellbeing support, use of data to identify trends and regular policy reviews. 

The four types of absence are planned absences (holidays, pre-booked leave), unplanned absence (sudden illness, emergencies), long-term absence (four weeks or more), and unauthorised absence (no notification or valid reason). 

HR can help to reduce absenteeism by combining preventative and reactive approaches. Preventative work includes introducing flexible working, manager training and supporting a wellbeing culture. Reactive work includes consistent policy application, return to work interviews, occupational health referrals and data analysis to spot trends and causes.
