Abstract This study examines the relationship between digital device usage and employee productivity, with sleep duration as a mediating variable. As digital devices have become integral to modern workplaces, concerns have grown regarding their adverse effects on employee well-being and performance. Drawing on existing literature in occupational health and sleep medicine, this study proposes and tests a mediation model in which excessive digital device usage disrupts sleep, which in turn reduces employee productivity. Primary data was collected from 150 employees across various industries using a self-constructed, five-point Likert scale questionnaire. The data was analysed using reliability analysis, descriptive statistics, correlation, regression, and mediation analysis via SPSS and PSPP. Results indicate that digital device usage has a significant negative effect on both sleep duration (R² = 0.26, β = −0.51) and employee productivity (R² = 0.38, β = −0.61), while sleep duration positively predicts productivity (R² = 0.40, β = 0.64). When both variables were considered together (R² = 0.52), sleep duration was confirmed as a significant mediator. These findings suggest that organisations should promote digital discipline, healthy sleep habits, and work-life balance initiatives to improve employee performance and well-being.
