The Impact of Sickness Absence on Small Businesses

If you run a small business, you’ll know that every single person counts. You don’t have the luxury of multiple departments or a spare hand to step in when someone is off.

When an employee calls in sick, it’s more than just an inconvenience — it can throw the whole week off balance. But when that sickness turns into a long-term absence, the pressure multiplies. You are trying to keep the business running, keep the rest of the team motivated, and figure out the “right” thing to do.

I’ve worked with countless small business owners and their managers in exactly this position, and I understand why it feels so overwhelming. The stakes feel high. On one hand, you want to support your employee — after all, they’ve been part of your journey. On the other, the reality is that their absence is affecting your ability to deliver for customers and putting extra strain on the rest of the team. Add in uncertainty about legal obligations and what you can and can’t ask, and it’s no wonder they feel at a loss for what to do next.

When I talk to owners and managers about how they’ve handled sickness absence in the past, the same themes come up again and again — and the truth is, they don’t happen because people are careless or indifferent. They happen because, without the right support, they are doing their best in a difficult situation and defaulting to what feels natural in the moment.

Common Pitfalls in Managing Sickness Absence

The first pitfall is silence. I see this most often when the illness is serious or sensitive, such as mental health challenges, cancer, or a bereavement-related absence. Business owners worry they might say the wrong thing, so they say nothing — at least not until the employee initiates contact. Sometimes it’s because they’re afraid of prying; sometimes because they think the employee will let them know when they’re ready to return. But silence can be interpreted as disinterest or a lack of care, and it makes it harder to rebuild that working relationship later. I’ve seen employees return after months away, already feeling on edge, and then lose confidence in the business because they felt “forgotten” during their absence.

Another common misstep is mishandling fit notes. Many small business owners receive the initial note, file it mentally as “off sick until [date],” and then focus on the immediate firefighting needed to keep the business going. It’s understandable — you’re busy, you’ve got customers to serve, and you don’t want to hover over someone who’s unwell. But without follow-up, you miss important opportunities to check how they’re doing, to explore whether they could do some adjusted duties, or to plan a phased return. The absence often ends up lasting longer than it needs to, simply because there’s been no structured conversation about next steps.

A further frustration I often hear from small business owners is when an employee stops keeping them updated altogether. At first, there’s a fit note, maybe a phone call, but then communication tails off. Weeks pass, another fit note appears, and the absence just seems to roll on without any sense of progress or return date. Employers often describe this as being “left in limbo,” and I understand why it’s so difficult — you’re trying to plan work, keep clients happy, and manage the rest of your team, all while not knowing if or when that person might come back.

In many cases, the employer has done very little — not out of neglect, but because they genuinely don’t know what to say, don’t want to put pressure on someone who’s unwell, or assume that the employee will get in touch when they’re ready. But here’s the problem: in the absence of regular, structured contact, a kind of stalemate sets in. The employee stays off sick, the employer feels increasingly frustrated, and then, often in a moment of exasperation, the employer decides they’ve “had enough” and wants to act. This is usually the point when they come to us for help.

The Cycle of Ineffective Absence Management

What tends to happen next is that we write to the employee, requesting updates or inviting them to a meeting. Sometimes this prompts a short flurry of activity, but if there’s no ongoing plan or follow-up process, it simply drifts back into the same cycle — the employee stays off, the employer waits, frustration builds, and we’re back where we started. This perpetual loop is damaging for everyone: the business can’t plan effectively, the employee becomes more disconnected from work, and the relationship between the two erodes. Breaking that cycle means stepping in earlier, setting expectations for communication, and having a clear process for reviewing the situation regularly. Without that, you risk months of uncertainty and an even more difficult conversation later.

Documentation Mistakes

Documentation is another area where small businesses trip up. Because the team is small and relationships are often personal, updates happen in quick chats or over messaging apps, and nothing gets written down. At the time, it feels friendly and efficient — no need for formality. But months later, when memories are fuzzy or there’s a disagreement about what was said, you have nothing concrete to fall back on. Without a written record, defending your actions in the event of a grievance or tribunal becomes far more difficult.

Delaying Expert Help

And then there’s the issue of waiting far too long to get expert help. Sometimes clients call me after six or nine months of absence, when frustration has set in and the relationship has already started to sour. By that point, options are more limited, and emotions are running high. The earlier you get professional input — whether that’s an HR consultant like me, a solicitor, or an occupational health specialist — the better the outcome is likely to be for both you and your employee.

The Role of Occupational Health and Why Early Involvement Matters

One of the most powerful, yet still underused, resources for small businesses is occupational health. Many owners hear the term and picture big corporations with on-site nurses or hefty budgets, but that’s a misconception. Occupational health is simply expert, independent medical advice designed to help you manage an employee’s health-related absence in a safe, fair and lawful way.

The Benefits of Occupational Health Advice

Here’s why early involvement matters so much. An occupational health professional can assess whether your employee is fit to work, either fully or in a reduced capacity, and can recommend specific, practical adjustments to help them return. These might include flexible start times, a reduced workload for an agreed period, a change in duties to remove physically demanding tasks, or permission to work from home part of the week. Importantly, their advice is objective. It’s not influenced by workplace politics or assumptions — it’s based on the employee’s medical situation and the demands of the job.

This objectivity protects you as an employer. If you act on occupational health advice, you can demonstrate that your decisions were reasonable, evidence-based, and not discriminatory. That matters enormously if the illness could be classed as a disability under the Equality Act 2010, where your duty to make reasonable adjustments is a legal one. I’ve also found that employees are often more receptive to adjustments suggested by a health professional than those suggested by an employer, as they see them as rooted in medical expertise rather than business convenience.

The Importance of Early Action

Getting occupational health involved early can also shorten absences. If you wait until someone has been off for six months before exploring adjustments, they may have become disconnected from work, anxious about returning, or physically deconditioned. The earlier you put a structured plan in place, the more likely you are to keep them engaged and confident about coming back.

Striking the Right Balance

Managing sickness absence isn’t about choosing between compassion and business needs — it’s about holding both in balance. That means maintaining regular, supportive contact from the very start, understanding and acting on medical advice, exploring adjustments creatively, and keeping a clear record of the steps, you’ve taken. It also means being honest with yourself about when you need outside help. Small business owners wear a lot of hats, but HR expert, legal advisor and occupational health assessor don’t have to be three of them.

When you approach absence management in this way, you reduce the risk of legal claims, protect the morale of your wider team, and often help your employee recover and return faster. You also protect yourself from the burnout and frustration that comes from feeling like you’re carrying the entire burden alone.
