Which of the following is NOT a method to reduce worker fatigue?

Increasing shift lengths is not a method to reduce worker fatigue because longer shifts can lead to higher levels of exhaustion and decreased alertness among workers. Fatigue often accumulates when individuals are required to work extended hours without adequate rest, leading to diminished performance and an increased risk of accidents and injuries.

In contrast, limiting work shift time and alternating assignments are strategies designed to mitigate fatigue by allowing workers to rest adequately and vary their tasks, preventing monotony and associated fatigue. Day/night shift rotations can also help manage fatigue by ensuring that workers have the opportunity to adjust to new schedules, but it must be done with consideration to how frequent shifts are rotated and the amount of rest provided between rotations.
