Abstract
Introduction: Sleep disorder is very common among employees and is considered as one of the crucial health problems. 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.

Abstract
Background and Objectives: In today’s demanding work environments, workforce resilience and ergonomic climate are recognized as critical factors for maintaining employee well-being and enhancing organizational productivity.
Methods:This cross-sectional, descriptive-analytical study investigated the relationship between ergonomic climate and employee resilience in a gas company. A total of 170 employees were selected through cluster random sampling. Data were collected using two validated instruments: the Ergonomic Climate Questionnaire and the Connor-Davidson Resilience Scale (CD-RISC). Statistical analyses were conducted using SPSS version 26, including descriptive statistics, Pearson correlation, one-sample t-tests, and regression analysis. Results:The findings indicated that the mean scores for ergonomic climate, operational performance, employee well-being, and individual resilience were significantly higher than the midpoint of the Likert scale. A positive and significant correlation was observed between all dimensions of ergonomic climate—namely, management commitment, employee involvement, hazard identification and control, and training and knowledge—and individual resilience. However, no significant relationships were found between demographic variables (age, gender, education, work experience) and resilience.
Conclusion: A favorable ergonomic climate plays a significant role in reducing stress and improving the psychological conditions of the workplace. Enhancing physical and mental health, reducing stress, increasing job satisfaction, and improving the quality of work life can all positively influence employees’ resilience in various ways. Therefore, organizational attention to ergonomic issues and the implementation of supportive strategies to improve workplace ergonomics can lead to an increased level of individual resilience among employees.
