Sleep disorders have a negative impact on job performance. The present study was regarding the relationship of sleep quality, sleepiness and sickness absence. Methods: This cross-sectional study was conducted on 400 employees of a gas company through random sampling. The study data were collected using the Pittsburg Sleep Quality Index )PSQI( and the Karolinska Sleepiness Scale )KSS(. Mann-Whitney U test and Spearman's correlation coefficient were applied for data analysis. Results: While %43.2 of the participants enjoyed satisfactory sleep quality, %56.8 had unsatisfactory sleep quality. Statistical tests indicated a significant difference in sickness absence of the personnel with good and poor sleep qualities )P = 0.0001(. Spearman's correlation coefficient )ρ = 0.777( indicated a statistically significant correlation between sleepiness index and sickness absence )P = 0.0001(. conclusions: The results showed a strong positive correlation in sleep quality, sleepiness index of the personnel and sickness absence; i.e. along with decline in sleep quality and incline in sleepiness, the personnel's sickness absence increased.
