Abstract
OBJECTIVES
For employees, work-time control (WTC) may protect against burnout and turnover. However, evidence from Korean workplaces is limited. This study aimed to examine whether WTC is associated with burnout and turnover intention and to test whether burnout mediates this relationship.
METHODS
We analyzed data from 4,745 wage workers in the 2024 wave of the Korean Work, Sleep, and Health Study. WTC was assessed across 6 domains, burnout was measured using the Korean Burnout Syndrome Scale, and turnover intention was assessed using a validated 4-item scale. Logistic regression was used to estimate the associations of WTC quartile with burnout and turnover intention, and mediation analysis was used to decompose the association between WTC and turnover intention through burnout.
RESULTS
Among 4,745 workers, the prevalence of burnout was 3.9% and turnover intention was 34.5%; both increased stepwise across lower WTC quartiles. In adjusted models, workers in the lowest WTC quartile had higher odds of burnout (odds ratio [OR], 3.95; 95% confidence interval [CI], 2.41 to 6.47) and turnover intention (OR, 2.24; 95% CI, 1.85 to 2.71) than those in the highest quartile. Mediation analysis showed that burnout explained 36.6% (95% CI, 22.3 to 51.0) of the association between WTC and turnover intention.
CONCLUSIONS
Lower WTC was linked to higher burnout and turnover intention, with burnout explaining more than one-third of this relationship.
Summary
Korean summary
근로시간 통제(work-time control, WTC)가 낮을수록 한국 노동자에서 번아웃과 이직 의도가 더 높게 나타났다. WTC가 가장 낮은 집단은 가장 높은 집단에 비해 번아웃 위험이 약 4배, 이직 의도는 약 2배 이상 높았다. 번아웃은 WTC와 이직 의도 사이 연관성의 약 36.6%를 매개하여, 근로시간 자율성을 높이는 것이 번아웃을 줄이고 이직 의도를 낮추는 데 기여할 수 있음을 시사한다.
Key Message
Lower work-time control (WTC) was associated with higher burnout and greater turnover intention among Korean workers. Workers in the lowest WTC quartile had nearly four times higher odds of burnout and more than twice the odds of turnover intention compared with those in the highest quartile. Burnout mediated about 36.6% of the association between WTC and turnover intention, suggesting that improving schedule control may reduce turnover partly by preventing burnout.

Abstract
OBJECTIVES
Preventing occupational injuries remains a significant challenge in Korea. A positive safety climate can contribute to reducing workplace injuries. However, the impact of safety climate on preventing occupational injuries among the Korean workforce has not been adequately explored. Therefore, this study aimed to investigate the relationship between the perceived safety climate and occupational injuries within the Korean working population.
METHODS
This study used baseline data from the Korean Work, Sleep, and Health Study (KWSH). The safety climate was measured using the brief version of the Nordic Safety Climate Questionnaire. Occupational injury was determined by whether injuries or accidents had occurred at workplaces in the past year. Logistic regression analysis was performed to examine the association between the safety climate and occupational injury.
RESULTS
Participants who reported an unfavorable workplace safety climate were more likely to experience occupational injuries. Multiple logistic regression analysis revealed that the adjusted odds ratio (OR) for occupational injuries in an unfavorable safety climate was 2.20 (95% confidence interval [CI], 1.38 to 3.51) compared to a favorable safety climate. Specifically, factors such as “not encouraging employees to follow safety rules when on a tight schedule” (OR, 2.02; 95% CI, 1.25 to 3.24) and “not helping each other work safely” (OR, 1.98; 95% CI, 1.17 to 3.25) were significantly associated with occupational injuries.
CONCLUSIONS
An unfavorable safety climate was associated with increased occupational injuries among Korean workers. Improving the safety climate in the workplace may reduce occupational injuries in Korea.
Summary
Korean summary
한국 노동인구집단에서도 안전풍토는 직업성 손상과 관련성이 관찰되었다. 이 같은 결과는 작업장의 안전풍토를 개선함으로써 직업성 손상을 예방할 수 있음을 시사한다.
Key Message
Safety climate was related to occupational injuries in the Korean working population. This result may indicate that occupational injuries can be prevented by improving the workplace safety climate. Workplace safety should be a high priority goal for management, and workers need to help each other for workplace safety.

Abstract
Korean Community Health Status Indicators (K-CHSI) is a model-based database containing annual data on health outcomes and determinants at the municipal level (<i>si/gun/gu</i>-level regions, including mid-sized cities, counties, and districts). K-CHSI’s health outcomes include overall mortality, disease incidence, prevalence rates, and self-reported health. Health determinants were measured in 5 domains: socio-demographic factors, health behaviors, social environment, physical environment, and the healthcare system. The data sources are 71 public databases, including Causes of Death Statistics, Cancer Registration Statistics, Community Health Survey, Population Census, and Census on Establishments and Statistics of Urban Plans. This dataset covers Korea’s 17 metropolitan cities and provinces, with data from approximately 250 municipal regions (<i>si/gun/gu</i>). The current version of the database (DB version 1.3) was built using 12 years of data from 2008 to 2019. All data included in K-CHSI may be downloaded via the Korea Community Health Survey site, with no login requirement (https://chs.kdca.go.kr/chs/recsRoom/dataBaseMain.do). K-CHSI covers extensive health outcomes and health determinants at the municipal level over a period of more than 10 years, which enables ecological and time-series analyses of the relationships among various health outcomes and related factors.
