The impact of the physical and mental workload on office workers’ wellbeing

Abstract

This study examines the impact of physical and mental workload on the wellbeing of employees in the Latvian banking sector by combining subjective self-assessment data with objective physiological measurements. In total, 98 employees from a major commercial bank participated in an online survey assessing ergonomic, psychosocial and organisational workload factors using a modified Job Strain Index. In addition, 14 employees underwent objective ergonomic testing, including grip strength assessment using a standardised dynamometer protocol. The results showed a high prevalence of musculoskeletal discomfort, particularly in the neck and shoulder region (26.2%) as well as visual fatigue and cognitive strain associated with digital overload and time pressure. Grip strength measurements indicated a shift from stronger to weaker categories by the end of the working day, suggesting possible accumulated muscular fatigue. These findings are consistent with international evidence showing that prolonged sedentary work, repetitive computer-based tasks and insufficient ergonomic adaptation may contribute to both physical and cognitive strain. Although the physiological measurement subgroup was relatively small, the study provides preliminary evidence that grip strength may be a useful supplementary indicator for monitoring early signs of functional fatigue in office settings.
