The Hidden Cost of Fatigue and Poor Sleep at Work
Why One Wellness Programme Does Not Fit Every Department
A tired employee does not always call in sick. They may arrive on time, attend every meeting and complete the shift. The effects can appear elsewhere: a slower response, a missed detail, a difficult conversation handled badly, or a decision postponed because concentrating feels harder than usual.
That makes fatigue easy to overlook. It is also easy to misread. A manager may see distraction; the employee may be coping with disrupted sleep, a demanding roster, stress at home, a health condition or several of these at once.
In the South African Depression and Anxiety Group’s 2024 Working Life survey, 75% of respondents said they thought about work when they were not at work. That finding does not measure how much they slept, nor does it prove work caused sleep problems. It raises a worthwhile question about whether employees have enough opportunity to switch off and recover.
Sleep concerns are widespread internationally. In ResMed’s 2024 survey across multiple countries, only 13% of respondents said they slept well every night. This is a survey of respondents, not a clinical measure or a global population estimate. Even with that limitation, it challenges the assumption that poor sleep is a rare personal problem with no place in workforce planning.
Fatigue has more than one source
A shift worker may struggle with changing start times. A driver may face long journeys and limited rest opportunities. A caregiver may finish a working day and begin another demanding set of responsibilities at home. An office employee may log off late and continue thinking through unresolved work.
Employers cannot control every factor in a person’s life. They can examine the factors within their influence: rosters, overtime, staffing, breaks, after-hours expectations and whether employees feel able to raise a safety concern. They can also make it easier for someone with persistent symptoms to seek professional help.
It is especially important to avoid treating a fatigue score as a diagnosis. Sleep difficulties may have many causes, including conditions that need medical assessment. A company should not infer a specific condition from a tired employee’s performance, and an employee should not have to share private medical details to be taken seriously.
How H360 WHIP can help
H360 WHIP can screen for potential health risks associated with sleep, fatigue and related conditions. At an aggregated level, it can help an employer see whether concerns cluster around particular departments, work environments or shifts, subject to suitable privacy safeguards.
That information can guide better questions. If fatigue concerns are higher on one shift, leaders might review roster changes, overtime and recovery time. If concerns occur across the organisation, they may need to examine broader pressures and access to care. An individual with concerning symptoms should be encouraged to obtain an appropriate clinical assessment.
The platform’s value is in making a possible pattern visible early enough for people to investigate and act. It cannot guarantee fewer errors or determine the cause of every tired day.
When leaders discuss productivity, they often ask how to help people do more. They should also ask whether their workforce has a fair chance to recover before doing it again tomorrow.
