How does the fatigue curve challenge differ when using 12-hour shifts compared to 8-hour shifts, especially during the night block?

Answer

The period of maximum physical and mental strain extends into the final hours of the shift.

The extra hours in a 12-hour block mean that critical periods where alertness typically drops are prolonged, increasing the chance of errors or safety issues toward the end of the work period.
