Objective: This study examined the relationship between the flexibility of work schedule arrangements and well-being among full-time workers prior to and after the coronavirus disease (COVID-19) outbreak in South Korea.
Methods: Data from the fifth 2017 and sixth 2020-2021 Korean Working Conditions Survey, including a final sample of 45,137 participants (22,460 males; 22,677 females), were used. Multiple logistic regression was performed to establish the association between schedule arrangement types and the 5-item World Health Organization Well-Being Index.
Results: The study found an association between flexible schedule arrangements and good well-being in 2017: "little flexibility" (odds ratio (OR), 1.33; 95% confidence interval (CI), 1.27-1.48), "moderate flexibility" (OR, 1.48; 95% CI, 1.28-1.71), and "high flexibility" (OR, 1.35; 95% CI, 1.06-1.72). During COVID-19, only workers with "high flexibility" were likely to have good well-being (OR, 1.49; 95% CI, 1.18-1.88), while the association between well-being and "low flexibility" (OR, 1.06; 95% CI, 0.96-1.17) and "moderate flexibility" types (OR, 0.66; 95% CI 0.59-0.75) decreased. This study found that flexible working hours may contribute to better well-being among full-time workers. However, the impact of the COVID-19 pandemic on working conditions and employee well-being should be addressed while setting working hours.
