In a small team, one person being off sick isn't a rounding error — it's a fifth of your capacity gone, orders that don't get fulfilled, and a WhatsApp message you're not sure how to reply to. Most small employers handle the first sickness absence on instinct, get it broadly right through luck, and only realise how much they didn't know when a second, longer or more complicated one arrives. The rules aren't complicated once you know them — the awkwardness comes from not knowing where the lines are.
Statutory Sick Pay is the floor, not the whole policy
Statutory Sick Pay (SSP) is the legal minimum you owe an eligible employee who's off sick for four or more days in a row, paid by you as the employer and set at a weekly rate reviewed each tax year. It's genuinely modest, which is exactly why so many small businesses assume 'we can't afford sick pay' when what they actually can't afford is enhancing beyond the statutory minimum — a different decision entirely. You don't need a company sick pay scheme to be legally compliant. You do need to know the SSP rules well enough to apply them consistently, because getting them wrong, even through ignorance, is still a legal exposure.
A written policy — even a short one — earns its keep here. It should say what counts as notifying you of sickness, by when, to whom, and what evidence is needed and from which day (self-certification for the first seven days, a fit note from a GP after that). Without it, every sickness becomes a fresh negotiation about what's reasonable, decided in the moment, under time pressure, which is exactly how inconsistent treatment creeps in.
The difference between short-term and long-term absence
Short, occasional absences — the odd day here and there — are usually best handled with a simple 'return to work' conversation: not an interrogation, just a brief, friendly check-in on the day someone's back, covering how they're feeling and whether anything work-related contributed. Done consistently for everyone, this alone catches a surprising amount: a pattern of Mondays off, a workload that's clearly become unmanageable, a personal issue that needs more support than a sick day.
Long-term absence — weeks rather than days — is a different problem and needs a different approach. Regular, low-pressure contact matters (not daily chasing, but a check-in every week or two), along with genuine curiosity about whether anything at work would help a return: adjusted hours, lighter duties, a phased comeback. For anything beyond a few weeks, getting occupational health input, even a one-off paid assessment, is usually money well spent — it gives you (and them) an independent, professional view on what's realistic, rather than guessing.
The mistake most small employers make isn't being too harsh on sickness. It's having no consistent process at all, so every case gets handled differently depending on how busy you are and how you feel about that particular person that week.
Where the legal risk actually sits
The biggest risk isn't sick pay calculations — it's treating someone unfairly because of an illness or disability, whether that's through impatience, informal pressure to come back too soon, or simply not making reasonable adjustments that would help someone stay in work. If a condition meets the legal definition of a disability (broadly, a physical or mental impairment with a substantial, long-term effect on daily activities), you have specific duties to consider adjustments — a phased return, different hours, equipment, or a change in duties. Ignoring that isn't just poor management; it's a genuine legal exposure for a business of any size, small ones included.
The other place small employers slip up is inconsistency: being flexible and sympathetic with one employee and rigid with another for the same kind of absence, often without meaning to, but with no record of why the treatment differed. Keep brief notes of return-to-work conversations and any adjustments discussed — not for bureaucracy's sake, but because if a decision is ever questioned, 'we treated this consistently and can show our reasoning' is the strongest position to be in.
The genuinely hard part: persistent short-term absence
The trickiest scenario for most small employers isn't one long illness — it's a pattern of short, separate absences that individually all seem legitimate but collectively make someone unreliable to schedule around. This is where a documented process matters most, because acting on a 'feeling' that someone's absence is excessive, without a clear record of the pattern and a fair conversation about it, is where informal pressure can tip into something that looks like unfair treatment. The fair route is transparent: flag the pattern, have an honest conversation about what's going on and whether support would help, set out clearly what improvement looks like, and only escalate formally if the pattern continues without explanation. It's slower than an off-the-cuff decision. It's also far less likely to blow up into a dispute later, and pairs well with a clear written contract that sets expectations from day one.
What to actually put in place this week
You don't need an HR department to get this right. A one-page sickness policy covering how to report absence, what evidence is needed and when, and how return-to-work chats happen; a habit of having that brief chat every time, without exception, so it never looks like it's only happening to one person; and a plan for who covers the work when someone's off, so a single absence doesn't become a crisis that colours how you treat the next one. None of it removes the disruption of a small team losing a pair of hands. It does mean you're handling it fairly, consistently, and in a way that protects both the business and the relationship with the person coming back.
