Abstract: This paper aims to investigate fatigue, sleepiness, daily sleep, and their association among 416 shift workers in the electronics manufacturing industry. Fatigue, sleepiness, and daily sleep were assessed using the multidimensional fatigue inventory, Karolinska sleepiness scale, and sleep diary, respectively. This study found that the prevalence of fatigue is 54.8% and sleepiness is 1.7%. There were 25.7% of workers who did not have an adequate amount of daily sleep. Significant associations (0.158 ≤ r ≤ 0.451) were found between all fatigue dimensions with sleepiness, and significant differences were found between night shift and morning shift workers in daily sleep. This study concluded that shift workers were prone to get fatigued and sleepiness and they also tend to get less sleep compared to non-shift workers. Thus, appropriate control measures should be implemented by the management to ensure that these issues could be curbed.
