Dealing with Frequent Absences? How to Manage Short-Term Sickness Legally and Fairly

Updated 10.08.2026

Short-term sickness is one of the most common HR headaches for small businesses, and one of the easiest to get legally wrong. Handle it too loosely and you risk inconsistency, unfair treatment claims, and absence creeping up unchecked. Handle it too rigidly and you risk penalising genuinely unwell staff, or missing a disability that needs reasonable adjustments.

The good news is that managing short-term sickness legally does not require a legal degree. It requires a clear policy, a consistent process, and an understanding of a handful of statutory rules that every employer needs to get right.

The Legal Basics Every Small Business Needs to Know

At a minimum, managing short-term sickness legally means:

• Having a written absence policy that sets out reporting expectations
• Requiring proper notification and evidence for each absence
• Paying Statutory Sick Pay (SSP) correctly and on time
• Holding return-to-work conversations after every absence
• Tracking absence patterns fairly and consistently, using clear trigger points
• Recognising when frequent short-term absence might actually be linked to a disability

Get these six things right and you are covering the vast majority of your legal obligations while also giving yourself the tools to manage genuine problems fairly.

How and When Employees Must Report Sickness

Your written policy, whether in the staff handbook or contract of employment, should set out exactly how and when an employee needs to report an illness. This typically means:

1. Who they need to contact (a named manager, not just “the office”)
2. By what time (for example, before their shift starts, or by a specific morning hour)
3. How (phone call rather than a text, if that is your preference)

Vague expectations lead to vague compliance. If your policy simply says “let us know if you’re off sick,” do not be surprised when people interpret that differently. Spell it out.

Self-Certification and Fit Notes: What’s Required and When

For short absences, the rules are straightforward:

• Up to 7 calendar days: The employee can self-certify. There is no requirement for a doctor’s note, but you can ask them to complete a self-certification form confirming the dates and reason for absence.
• Beyond 7 calendar days: You can require a fit note (formally known as a Statement of Fitness for Work) from a GP or other authorised healthcare professional.

Keep in mind that 7 calendar days includes weekends, so an employee off sick from a Thursday to the following Wednesday has hit the threshold, even though they have only missed a handful of working days.

Statutory Sick Pay: What Changed in April 2026

This is the area that has shifted the most recently, and it is worth getting right, because payroll errors here are one of the easiest ways to end up with a grievance.

From 6 April 2026, three important changes took effect:

• SSP is now payable from day one of sickness, rather than after three “waiting days” as under the old rules
• The Lower Earnings Limit has been removed, meaning eligibility is no longer restricted to employees earning above a set weekly threshold
• The rate is now calculated as the lower of the flat statutory weekly rate (£123.25 for 2026/27) or 80% of the employee’s average weekly earnings, so lower-paid staff receive a proportionate amount rather than being excluded entirely

In practice, this means more of your staff now qualify for SSP, and it applies from the very first day of an absence rather than only kicking in for longer periods. If your absence policy or payroll process still references “waiting days” or an earnings threshold, it needs updating now.

SSP at a glance: what small businesses need to know

When Frequent Short-Term Sickness Might Actually Be a Disability

Here’s a scenario worth thinking through. An employee has had six short absences in four months, each just a day or two, each for a different reason on the surface, migraines, a bad back, fatigue. Individually, none of them look serious. Together, they might be pointing to something else entirely.

Recurring short-term absences can sometimes be linked to an underlying, undisclosed disability or health condition. If that turns out to be the case, you have a duty under the Equality Act 2010 to consider reasonable adjustments before taking any formal action on attendance. Treating a disability-related pattern of absence the same way you would treat unrelated one-off illnesses is a common and costly mistake.

If you spot a pattern that looks like it could be connected, pause before moving to a formal process, and have a supportive conversation first. Our Equality, Diversity and Inclusion Services team can help you work through exactly this kind of situation.

Bringing It All Together

Getting the legal basics right, clear reporting, correct SSP, and awareness of disability considerations, gives you a solid, defensible foundation. From here, the next step is building a consistent process for tracking absence, running return-to-work interviews, and knowing when a pattern needs a more formal conversation, which is exactly what we cover below.

Why a sickness absence policy is essential

Many small businesses operate without a formal sickness absence policy. This is one of the most common and costly gaps in HR compliance, because without a policy in place:

• You have no consistent standard to apply, which makes it harder to take action when absences become problematic
• Employees do not know what is expected of them when they are unwell
• If you do need to move toward a formal process or dismissal, the lack of a documented procedure significantly increases your tribunal risk

A sickness absence policy does not need to be lengthy or complex. At Centric HR, we help small businesses put straightforward, compliant policies in place that work in practice, not just on paper. You can browse our range of HR document packs, or speak to us about a bespoke policy for your business.

What a sickness absence policy should cover

A legally sound sickness absence policy for a small business should include:

• Reporting procedure: who the employee must contact, by what method, and by what time on their first day of absence
• Self-certification: confirmation that employees can self-certify absences of up to 7 calendar days without a fit note
• Fit note requirement: that a fit note from a registered healthcare professional is required for any absence beyond 7 calendar days
• SSP entitlement: a clear statement of the employee’s statutory sick pay rights and any enhanced sick pay your business offers
• Return-to-work procedure: confirmation that a return-to-work interview will be conducted following every absence, however short
• Absence trigger points: the thresholds at which a formal review will be initiated, for example the Bradford Factor or a set number of absences in a rolling period
• Disability and reasonable adjustments: a note that absences related to a disability will be handled separately and with appropriate care under the Equality Act 2010

Return-to-work interviews: what they are and why every small business should use them

A return-to-work interview is a brief, structured conversation between a manager and an employee on their first day back after any sickness absence. It takes around 10 to 15 minutes and should be supportive in tone, not confrontational.

Return-to-work interviews are consistently cited by ACAS and HR professionals as the single most effective tool for managing short-term sickness absence, for two reasons: they show genuine concern for the employee’s wellbeing, and they act as a natural deterrent to casual or non-genuine absences.

What to cover in a return-to-work interview

• Welcome the employee back and confirm they are well enough to be at work
• Ask them to briefly describe the reason for the absence
• Collect and sign off the self-certification form (for absences of 7 days or fewer)
• Check whether any fit note has been provided and whether it recommends any adjustments
• Ask whether there is anything the business can do to support them going forward
• Note the absence on the employee’s record
• If a pattern is emerging, address it calmly at this stage, before it reaches a formal trigger point

The conversation should be documented. A short written record of what was discussed, signed by both parties, protects both the employee and the business if the situation escalates later.

How to identify and address patterns of short-term absence

Not all short-term sickness is genuine, and not all patterns of absence are intentional. The key for small business owners is to identify what is happening and respond in a measured, consistent, and legally sound way.

Using the Bradford Factor

The Bradford Factor is a formula used to measure the impact of short, frequent absences on a business, giving more weight to multiple short absences than to one longer period of illness. The formula is: S x S x D, where S is the number of separate absence spells and D is the total number of days absent in a rolling period.

Many businesses use trigger points based on Bradford Factor scores to prompt a formal review. For example, a score of 50 or above within a 12-month rolling period might trigger an informal discussion, and a score of 150 might trigger a more formal capability review.

The Bradford Factor is a useful management tool but should not be applied mechanically. Always consider the context: an employee managing a chronic condition or a disability may have a high score through no fault of their own, and treating them the same as someone with unexplained casual absences could expose you to a disability discrimination claim.

When patterns require formal action

If informal conversations and return-to-work interviews are not resulting in improvement, and no underlying health or personal issue has been identified, it may be appropriate to move into a formal process. This is where small businesses most commonly make mistakes.

Common errors include:

• Moving straight to disciplinary action when the correct route is a capability process
• Failing to follow a documented procedure, which makes any dismissal much harder to defend
• Not seeking medical evidence or an occupational health referral before making decisions about an employee’s fitness for work
• Treating absence related to pregnancy, disability, or a mental health condition the same as general sickness absence

If you are unsure how to proceed with a persistent short-term absence situation, speaking to an HR professional before you act is significantly cheaper and less stressful than managing an employment tribunal claim afterwards. Centric HR’s pay-as-you-go HR support gives you access to expert advice exactly when you need it, with no monthly commitment.

When should a small business get professional HR support for sickness absence?

There are some sickness situations that small business owners should not try to handle without professional guidance. These include:

• Long-term sickness crossing into short-term patterns: when an employee’s repeated short absences appear linked to an underlying health condition, the legal landscape becomes more complex
• Suspected disability: if there is any possibility that an absence pattern is connected to a condition that qualifies as a disability under the Equality Act 2010, you must handle the situation differently, including considering reasonable adjustments before taking any formal action
• Mental health absences: these require a more sensitive and structured approach; getting it wrong carries significant reputational and legal risk
• Considering dismissal: if you are thinking about dismissing an employee because of their absence record, you need to follow a legally correct process; failure to do so is one of the most common causes of unfair dismissal claims
• You have no sickness policy: trying to take formal action against an employee without a documented policy in place is very difficult to defend
