Battery Discharge from Monday to Friday: Background Social Stress at Work is Associated with more Rapid Accumulation of Fatigue

Abstract

Purpose This field study investigated the effects of background social stress at work on the weekly course of evening fatigue. Methods Male employees of a Swiss organisation reported their fatigue after work and at 9 pm in the evening over three weeks. A total of 482 evening fatigue measurements from 34 male participants were subjected to multilevel analysis. Results Sleep quality in the previous night and fatigue after work predicted evening fatigue. Evening fatigue was not associated with the time spent on daily housework or child care. There was a linear increase in evening fatigue across weekdays and a main effect of workplace social stressors on evening fatigue. Sleep quality during the previous night mediated the link between background social stressors and evening fatigue. Moreover, an interaction between workplace social stressors and working days indicated that fatigue accumulated faster during the working week in those reporting a high level of social stress at work. Conclusion Social stress at work seems to accelerate the loss of resources over consecutive workdays. The analysis of workplace social stressors and other potential moderators of resource dynamics contributes to our understanding of work-related stress, including the role of background stressors and the temporal dynamics of resource loss.

Enhancing operations management through smart sensors: measuring and improving well-being, interaction and performance of logistics workers

“…This variable is "1" for Monday, "2" for Tuesday and so on, till "5" for Friday. A recent study has confirmed that across weekdays, employees' fatigue may vary (Elfering et al, 2021).…”

Examining workweek variations in computer usage patterns: An application of ergonomic monitoring software

“…This finding is consistent with the study by Riley et al, which reported a decline in cognitive and attentional abilities in the afternoon and a corresponding increase in errors throughout the day [ 28 ]. Although employees may partially recover from mental fatigue and stress from mental detachment, such as exercise and sleep in the evening, previous studies have shown that this recovery is limited, and their mental resources do not fully restore, accumulating over the workweek [ 29 ]. As a result, employees report higher levels of mental fatigue, stress, and negative mood on Thursdays and Fridays, compared to Mondays and Tuesdays [ 30 ].…”

Service Quality Implications of Long Periods of Consecutive Working Days: An Empirical Study of Neonatal Intensive Care Nursing Teams

“…Both high daily workload (NPR) and high cumulative workload (ACDW) act as stressors, leading to a modulation effect of NPR on ACDW. Elfering et al (2021) have shown that fatigue increases with consecutive working days but accumulates faster at higher levels of daily…”
