Studies show that even moderate sleep deprivation can impair both cognitive and motor performance equivalent to a blood alcohol content of up to 0.1%.1,2 No organisation would allow employees to work when under the influence of alcohol or other substances. Yet fatigue—which can lead to comparable impairments in performance and safety—often does not receive the same level of attention. The few companies who do have fatigue management policies in place typically stop at limiting work hours.
Employee fatigue not only negatively impacts attendance, performance, engagement and wellbeing, but it can also be triggered by job factors that are the responsibility of the organisation. There are initiatives that organisations can implement to reduce the negative impact of employee fatigue, but they must target all levels—from the top floor to the shop floor.
