When Fatigue Is More Than Just Feeling Tired
Everyone feels tired sometimes, but fatigue that impairs concentration, reaction time or physical capacity, especially in safety-critical roles, is a different matter. A GP assesses whether fatigue is affecting concentration, reaction time, physical capacity or your ability to work safely, and whether a sick leave certificate is clinically appropriate.
If fatigue is affecting your ability to work safely, book a consultation to have it properly assessed.
- Persistent exhaustion not explained by a poor night's sleep
- Difficulty concentrating or slowed reaction time
- Fatigue affecting your ability to safely drive, operate machinery, or perform physical tasks
- Fatigue accompanied by other symptoms suggesting an underlying cause
What Your GP Assesses During the Consultation
The GP will ask how long the fatigue has lasted, whether anything specific triggered it, such as illness, poor sleep, medication, or a mental health factor, and how it's specifically affecting your capacity to do your job safely. This helps distinguish ordinary tiredness from fatigue that genuinely warrants time off.
When Is Fatigue Medically Significant Enough for a Certificate?
Not all tiredness needs a certificate, and the GP's role is to determine whether your fatigue crosses that threshold. Factors like impaired concentration in a desk job, or reduced reaction time in a role involving driving or machinery, weigh heavily in that assessment, more than the sensation of tiredness alone.
Fatigue and work safety
When Fatigue Becomes a Work-Safety Problem, Not Just Tiredness
Fatigue becomes medically important at work when it affects concentration, reaction time, judgement, physical endurance or the ability to complete duties safely. The threshold differs for a desk worker and someone driving long distances, operating machinery, working at heights or doing a night shift.
A certificate can address the current period of impairment, but persistent unexplained fatigue also needs assessment of the underlying cause. Safe Work Australia identifies fatigue as a workplace hazard that can affect physical and mental performance.
Driving and Machinery
Reduced alertness and slower reaction time make fatigue a safety issue even when the person can still stay awake. This matters particularly where driving, machinery, heights or other safety-sensitive tasks are part of the role.
Shift Work and Recovery Time
Night work, rotating rosters and inadequate recovery between shifts can create a different fatigue pattern from fatigue caused by illness. Safe Work Australia's worker guidance explains how work patterns can contribute to fatigue risk.
Persistent Fatigue Needs Investigation
If rest does not improve the problem or the pattern keeps recurring, the next useful step is to find the cause rather than repeat certificates.
Look beyond the current absence
Ongoing fatigue can have many causes and may need broader clinical assessment. Healthdirect's fatigue guidance explains common causes and when medical review may be appropriate.
Work absence evidence
Where fatigue makes an employee temporarily unfit for work, ordinary personal-leave evidence may be relevant. Fair Work explains the evidence principles for personal and carer's leave.

Frequently asked questions
View all FAQsNot for ordinary tiredness. The GP needs to determine that your fatigue genuinely affects your ability to work safely or effectively, which is a higher bar than simply feeling worn out.
Yes, in most cases. The GP will ask about your symptoms, how long they've lasted, and how they're affecting your work, and can usually determine appropriate next steps by phone.
Mention this specifically during your consult. Fatigue that affects your ability to safely drive or operate machinery is taken seriously, and the GP will factor workplace safety into their assessment.
This depends on the underlying cause and severity, and is determined by the GP during your consultation. Persistent or worsening fatigue may also warrant further investigation with your regular GP.
No. The certificate confirms that you were assessed as unfit for work for the covered period, without disclosing the specific cause. Employers can independently verify a certificate through certificate verification portal.

Support and Resources
Multi-Day Sick Leave CertificateFor a multi-day medical certificate, if your condition requires more days to manage your health.
Fatigue is more than ordinary tiredness when it is persistent, unusually severe or starts affecting concentration, physical stamina, driving or daily activities. Many medical, sleep and lifestyle factors can contribute. A doctor can assess the pattern and impact of your fatigue and determine whether temporary leave, further tests or additional care may be appropriate.
