Summary
Flexible working hours can negatively impact health. Analyzing the patterns in work schedules, particularly disruptions to circadian and weekly rhythms, helps predict these health impairments.
Area of Science:
- Occupational Health
- Chronobiology
- Workforce Management
Background:
- Flexible working hours are increasingly common but linked to adverse health outcomes.
- Variability in work schedules is a key factor, yet methods for its assessment and predictive power are limited.
Purpose of the Study:
- To develop and apply a time series analysis approach to quantify flexible working hour variability.
- To identify patterns in flexible work schedules and their association with health impairments.
Main Methods:
- Time series analysis and spectral analysis were applied to 4-week working hour data from 137 employees across 15 German companies.
- Cluster analysis of spectral data identified 5 distinct patterns of flexible working hours.
Main Results:
- Five clusters of flexible working hour patterns were identified.
- Suppression of circadian and weekly rhythms within flexible work schedules correlated with the most severe health impairments.
- Impairments were particularly noted in circadian-controlled functions such as sleep and digestion.
Conclusions:
- Analyzing the periodicity of flexible working hours is a promising method for predicting health impairments.
- Further research is warranted to explore this approach for occupational health and well-being interventions.
