Managing occupational stress among heavy vehicle drivers in the Sri Lanka Navy

Abstract

Occupational stress is a significant factor influencing the health, well-being, and performance of heavy vehicle drivers, particularly those serving in military organizations such as the Sri Lanka Navy (SLN). This study investigates the causes and consequences of workplace stress among heavy vehicle Transport Assistants (TAs) in the SLN, identifying key stressors and proposing mitigation strategies. Using a mixed-method approach, data was collected from a sample of 221 drivers through structured questionnaires and analyzed using descriptive statistics, correlation, and regression models. The findings revealed that fatigue, long working hours, irregular schedules, inadequate ergonomics, lack of job support, and inappropriate physical conditions were significant predictors of stress. Notably, stress was linked to reduced job satisfaction, increased turnover intention, and compromised performance. The study recommends interventions, including ergonomic improvements, stress management training, job rotation, and enhanced work-life balance initiatives, to mitigate stress and enhance the operational efficiency and well-being of SLN drivers. These findings contribute to the broader understanding of occupational stress management in military contexts and provide actionable strategies for improving driver welfare and safety.
