Korea is well known for long work hours. This study examined the effect of not only the total amount of working time but also work schedules on individuals’ subjective well-being in Korea. Drawing on the 2014 Korean Time Use Survey data, the authors selected currently employed people aged 19–65 and examined the effects of total work hours as well as work schedules on feeling rushed, feeling tired, and life satisfaction. Based on the ordered logistic regression analysis, long work hours were negatively related to subjective well-being regardless of work schedules. After adding an interaction between standard and nonstandard work schedules, the study found that while work hours during both standard and nonstandard schedules are associated with declines in psychological status, the negative effect of working time during nonstandard work schedules on subjective well-being is stronger as the work hours during standard schedules decrease.
