When sickness hits, how OTs and business owners keep care moving

Nasty bugs, surprise migraines, sick kids, even the occasional adult case of chickenpox – illness has a way of arriving exactly when the diary is full. For Occupational Therapists, being unwell rarely affects just one person. It impacts appointments, client safety, rescheduling, team capacity and the financial stability of a service.

In allied health, illness is never just personal. It sits at the intersection of duty of care, workforce sustainability and if you’re a business owner, the realities of running a practice. When a clinician can’t work, the ripple effect is immediate and often far larger than a single cancelled appointment.

When illness disrupts more than your day

Many OTs recognise the instinct to keep going when they’re sick. A sore throat, a lingering cold or exhaustion after a busy conference might normally be something you push through because the week is full and people are relying on you.

That mindset often develops early in a career. When you’re building a caseload or working as a sole trader, the pressure to maintain appointments can feel intense. Cancelling sessions means lost income, disappointed families and a backlog of work waiting when you return.

Duty of care when you’re unwell

Over the past few years, the profession has shifted its thinking about illness. Previously, many clinicians worked through symptoms as long as they could physically manage the session. Now the focus is much more firmly on client safety and infection control.

One unwell therapist can quickly affect an entire caseload, especially when working with children, older adults or people with complex health needs. Illness doesn’t just affect the therapist, it can expose multiple households and potentially disrupt care for a large number of clients.

Because of this, many clinics have become much clearer about expectations. If a therapist is unwell, they stay home. If symptoms suggest something infectious, testing or isolation may be required. These decisions aren’t just about protecting the clinician, they protect the entire community around the service.

Rescheduling isn’t just moving an appointment

At first glance, cancelling a session might seem like a simple administrative task. In reality, rescheduling can be one of the most difficult parts of managing illness in our line of work.

Many clinicians operate with diaries booked weeks in advance. When a day disappears unexpectedly, there is rarely a spare slot waiting to absorb those clients. The missed appointments can create a backlog that extends well beyond the original sick day.

This challenge becomes even more complicated when sessions involve multiple professionals. Joint visits with builders, equipment suppliers or support coordinators can take weeks to organise. If the therapist becomes unwell on the day, it may take significant time to bring everyone back together again.

Telehealth can sometimes provide a temporary solution, particularly for consultation or follow-up conversations. However, most clients do not expect or request telehealth simply because a therapist is sick. In many cases the appointment simply needs to move.

The hidden cost of sick leave and cancellations

For practice owners, illness has an additional layer of complexity. When clinicians are unable to see clients, revenue disappears immediately while operating costs remain unchanged.

A single day of cancelled appointments may represent several hours of billable work. When illness affects multiple clinicians, or when winter brings repeated cancellations due to sick families, the financial impact can grow quickly.

This is one reason the true cost of professional development, conferences or training days is often underestimated. It is rarely just the cost of attending. It also includes the income that would normally be generated during that time, along with the administrative effort required to reorganise the diary.

Many practices eventually learn to plan around a realistic working year rather than assuming full capacity every week. Even then, unexpected illness can still disrupt carefully balanced schedules.

Why sole traders feel it most

For sole traders, illness can create a particularly difficult situation. Without a team to share the workload, the decision to cancel appointments often has direct financial consequences.

In the early stages of private practice there may also be little financial buffer to absorb lost income. As a result, many clinicians shift their workload rather than stopping entirely. Face-to-face sessions might be cancelled, but report writing, administration or funding applications continue from home.

When work cannot be completed during the day, it often moves into evenings or weekends. Over time, this pattern can contribute to fatigue and burnout, particularly when illness occurs repeatedly during busy periods of the year.

Planning ahead with policies and immunisations

One of the quieter lessons from recent years is the importance of planning for illness before it occurs. Clear policies about sick leave, infection control and client communication can help clinics respond quickly and consistently when someone becomes unwell.

Vaccination is another area where expectations and reality sometimes differ. In hospital settings, immunisation status is routinely recorded and monitored. In private practice, the process is often far less structured.

Families may assume health professionals are up to date with recommended vaccinations, particularly when working with infants, older adults or medically complex clients. For some clinics, this has prompted conversations about whether immunisation records should be documented more clearly as part of workplace systems.

The goal is not to create unnecessary bureaucracy but to ensure practices are prepared for situations that inevitably arise during the year.

Making Occupational Therapy work sustainable

Illness is a normal part of life, but the profession has historically struggled to make space for it. When diaries are full and demand for services is high, taking time off can feel uncomfortable or even irresponsible.

In reality, sustainable Occupational Therapy practice depends on recognising that sickness will occur and building systems that can absorb it. That might mean flexible scheduling, shared caseloads, telehealth options or realistic workload planning across the year.

It also requires a cultural shift within the profession. Taking time to recover when you are unwell is not a sign of weakness or lack of commitment. It is a necessary part of protecting both clinicians and the people they support.

Key takeaways for OTs
• Illness affects far more than a single appointment – it can disrupt entire caseloads and teams
• Infection control and client safety should guide decisions about working while sick
• Rescheduling sessions can be complex, particularly when multiple professionals are involved
• Sick leave and cancellations create significant hidden costs for private practices
• Sole traders often feel the greatest pressure to continue working while unwell
• Clear policies, communication and vaccination planning can help clinics manage illness more effectively
• Sustainable OT practice requires systems that allow clinicians to rest and recover when needed
