Objectives: This examine the effect of shift work type on sleep disturbance and the mediating role of subjective well-being. Methods: Using secondary data from the 7th Korean Working Conditions Survey, 2,756 wage workers aged 20 or older were analyzed with descriptive statistics, analysis of variance, multiple regression, and PROCESS Macro (Model 4). Results: Sleep disturbance varied by shift type; split and permanent shifts exhibited the highest and lowest levels, respectively. Older age, marital status, and having children were associated with sleep disturbance. Subjective well-being was negatively related to sleep disturbance but did not mediate the association between shift type and sleep disturbance. Conclusions: Irregular shifts, particularly split shifts, increase sleep disturbance. Furthermore, subjective well-being reduces sleep disturbance but does not buffer the effect of shift type. Accordingly, sleep health interventions should address both scheduling and emotional well-being.
