Fatigue doesn’t always look like poor performance. Sometimes people work harder to hide it. This article explores how human factors, Safety-II and emerging fatigue research can help organisations identify hidden risk before it becomes an incident, absence or resignation.

This article explores why improving safety culture requires redesigning work systems rather than simply asking people to try harder.
