A rest-hours sheet records time. It does not necessarily record recovery.
It cannot show whether sleep was uninterrupted, whether the rest period fought against the body’s circadian rhythm, or whether noise, stress and repeated call-outs made meaningful sleep unlikely.
Compliance with work-and-rest requirements is essential. But fatigue management begins where timekeeping ends.
A schedule can be compliant on paper while still leaving someone poorly prepared for the next safety-critical task.
Alongside “Were the required hours recorded?”, perhaps the operational question should be:
“Did this person have a realistic opportunity for adequate, undisturbed sleep?”
How does your fatigue review look beyond the spreadsheet?
