Backgrounds Irregular and unpredictable work schedules have become more common in most societies. The purpose of this study was to investigate the association between unpredictable work schedules and depressive symptoms in Korea. Methods Data from 34,486 workers who participated in the Korean Working Condition Survey in 2017 was used. Unpredictable work schedules were measured by questions about the frequency of changes in work schedule and limited advanced notice. Depressive symptoms were assessed by a single item asking if the participants had depressive symptoms over the last 12 months. Multivariable adjusted logistic regression analysis was used to calculate odds ratios for high depressive symptoms. Results The odds ratio (OR) for depressive symptoms was significantly higher in the workers with unpredictable work schedules compared to those with predictable work schedules after controlling for age, sex, education, salary, marital state, occupation, contract period, full time vs part-time, shift work, weekly working hours and having child (OR=2.43, 95% CI 1.93-3.07). Conclusion Unpredictable work schedules were associated with depressive symptoms controlling for the other dimensions of precarious employment in a representative working population in Korea.
