Introduction and Purpose: Firefighting is known as one of the most difficult and stressful service jobs in the world. Firefighters are constantly exposed to numerous physical and psychological hazards due to their rescue and firefighting missions. The present study aimed to investigate the relationship between workload and occupational fatigue with work-family conflict among firefighters.
Methods: This descriptive-analytical cross-sectional study was conducted in 2025 on 142 firefighters selected using simple random sampling. Data were collected using three questionnaires, including the NASA-TLX Workload Questionnaire (score range: 0-100), the Swedish Occupational Fatigue Inventory (score range: 0-200), and the Carlson et al.’s Work–Family Conflict Questionnaire (score range: 18-90). Pearson correlation coefficients and multiple linear regression were used to assess the relationships between variables.
Results: The mean scores for workload (63.12), occupational fatigue (71.12), and work-family conflict (43.60) were at high, moderate, and moderate levels, respectively. Work-family conflict showed a significant positive correlation with workload (r(140):0.44, P<0.001) and occupational fatigue (r(140):0.51, P<0.001), but it was not significantly correlated with age (P=0.432), work experience (P=0.602), or education (P=0.081). Regression analysis indicated that occupational fatigue (β=0.48) and workload (β=0.34) were significant positive predictors of work-family conflict. The final model explained 43% of the variance (R²=0.43).
Conclusion: Workload and occupational fatigue were positively and significantly associated with work–family conflict among firefighters. These findings highlight the importance of addressing workload management and job burnout in occupational health promotion programs.
