Do small businesses need a staff sickness policy?
If you run a small business and you don't have a formal sickness policy, you're not alone. It's one of the most commonly overlooked HR basics — often because it feels unnecessary when your team is small and you know everyone personally. The thinking goes: if someone's ill, they call in, you wish them well, and they come back when they're better. What's there to write down?
Quite a lot, as it turns out.
The short answer is yes — and here's why
A sickness policy isn't bureaucracy for its own sake. It protects your business, protects your employees, and creates consistency that becomes critical the moment something goes wrong. Without one, you're making it up as you go — and that's where problems start.
Consider what happens without a policy in place. One employee calls in sick and you ask no questions. Another goes off for three weeks and you're not sure when you're supposed to make contact, what you're allowed to ask, or whether you can eventually do anything about it. A third takes a pattern of Mondays off and you're unsure whether you can address it without a discrimination risk. A policy gives you the framework to handle all of these situations consistently and confidently.
What a sickness policy should cover
A good sickness policy doesn't need to be long. It needs to be clear. At a minimum it should cover:
Notification procedure. How should employees let you know they're unfit for work? By what time? Who should they contact — their line manager, or someone else? Defining this removes ambiguity and ensures you're not finding out at 9:15 that a key person isn't coming in.
Fit notes and medical evidence. Employees don't need a fit note for the first seven days of absence — self-certification covers this period. After seven consecutive days, a fit note from their GP is required. Your policy should make this clear, including what happens if someone refuses to provide one.
Statutory Sick Pay. Employees who meet the qualifying conditions are entitled to SSP from day four of illness. Your policy should set out whether you offer anything above SSP — an occupational sick pay scheme — and if so, on what terms: how much, for how long, and whether it's discretionary or contractual.
Keeping in touch. Regular, supportive contact during absence is both good practice and legally important. Your policy should set out how often you'll make contact and in what format. This isn't about pressuring people back — it's about maintaining the relationship and staying informed.
Return to work. Return-to-work conversations are one of the most effective tools for managing absence, and one of the most underused. A brief, informal conversation on the day someone returns — not interrogative, just a genuine check-in — helps identify whether there's anything underlying the absence and reinforces that you've noticed and you care. It also acts as a deterrent for casual absence, without being punitive.
Long-term sickness. If an employee is off for four weeks or more, a different approach is needed — occupational health referrals, regular welfare meetings, consideration of reasonable adjustments, and ultimately a process for managing the situation if a return to work isn't possible. Your policy should signal that this process exists, even if the detail sits in a separate procedure.
Short-term persistent absence
This is one of the most frustrating challenges for small employers: the employee who is never off for long enough to trigger concern, but who is absent frequently. A pattern of one or two days here and there, often on specific days, can be just as disruptive as a longer absence — and harder to address without a policy framework.
A trigger point system — for example, the Bradford Factor, or a simpler threshold of a set number of occurrences in a rolling period — gives you a defensible basis for having a formal conversation. Without something written down, any attempt to address persistent short-term absence risks looking arbitrary or, worse, discriminatory.
The discrimination risk
This is where small employers often get caught out. Absence management without a policy can quickly become inconsistent — and inconsistency creates discrimination risk. If you manage one employee's absence more robustly than another's without a clear, applied framework, you may inadvertently be treating someone less favourably because of a protected characteristic. Disability is the most common flashpoint: many underlying health conditions that drive absence are disabilities under the Equality Act, triggering a duty to make reasonable adjustments.
A policy won't eliminate this risk entirely, but it substantially reduces your exposure by ensuring you apply the same process to everyone.
What about very small teams?
Even if you have two or three employees, a sickness policy is worth having. In fact, in a very small team, a single long-term absence can be existential for the business. The clearer your framework for managing it, the more options you have — and the less likely you are to make a costly mistake under pressure.
It doesn't need to be complicated. A well-written one or two page policy, communicated clearly and applied consistently, is sufficient. The goal is a document that your employees understand and that you're confident using.
The bottom line
A sickness policy is one of those HR fundamentals that feels unnecessary until the moment you need it — at which point not having one becomes a real problem. Getting it in place before something goes wrong is straightforward, inexpensive, and one of the most practical things you can do to protect your business.
