What is fatigue?

Fatigue in a work context is more than feeling tired and drowsy. It is a state of mental or physical exhaustion (or both) that reduces a person’s ability to perform work safely and effectively.

Symptoms of fatigue include:

  • slower reactions
  • reduced ability to process information
  • memory lapses
  • absent-mindedness
  • decreased awareness
  • lack of attention
  • reduced ability to identify and calculate risk
  • reduced coordination
  • changes in behaviour (e.g. arriving late for work).

Why is fatigue a problem in the workplace

Fatigue can result in:

  • errors and accidents
  • ill-health and injury
  • reduced productivity
  • low team morale.

What can contribute to fatigue?

Fatigue can be caused by factors that are work related, not related to work, or a combination of both. The effects can accumulate over time.

Fatigue may result from prolonged or intense mental or physical activity, sleep loss or extended wakefulness, or disruption of a person’s body clock (e.g. through shift work). It is also related to workload because workers are more easily fatigued if their work is machine-paced, complex or monotonous.

What can be done about fatigue?

Both the employer and worker have responsibilities to manage the risks from fatigue.

Employers should conduct a risk assessment that takes into account the fatigue risk factors relevant to their operation and develop a fatigue management plan.

The fatigue management plan should aim to maintain alertness and guard against fatigue.

Workers need to take responsibility for their own health and safety by adhering to relevant policies and procedures outlined in the fatigue management plan.
