Background: Although sick leave is a complex phenomenon, it is believed that there is potential for prevention at the workplace. However, little is known about this potential and what specific measures should be implemented. The purpose of the study was to identify perceived reasons to take work-related sick leave and to suggest preventive measures. The study was completed before the COVID-19 pandemic emerged, and the risk factors identified may have been amplified during the pandemic. Methods: An in-depth cross-sectional survey was conducted across a randomly selected sample of hospital nurses in Norway. The national sample comprised 1,297 nurses who participated in a survey about their sick leave during the previous 6 months. An open-ended question about perceived reasons for work-related sick leave was included to gather qualitative information. Results: Among hospital nurses, 27% of the last occurring sick leave incidents were perceived to be work-related. The most common reasons were high physical workload, high work pace, sleep problems, catching a viral or bacterial infection from patients or colleagues, and low staffing. Conclusions: Over a quarter of the last occurring sick leave incidents among Norwegian hospital nurses are potentially preventable. To retain and optimize scarce hospital nursing resources, strategies to reduce work-related sick leave may provide human and financial benefits. Preventive measures may include careful monitoring of nurses' workload and pace, optimizing work schedules to reduce the risk of sleep problems, and increasing staffing to prevent stress and work overload.

This study examined the impact of job demand and organizational culture on new task difficulties, burnout, and job satisfaction using a survey data of 145 family specialists in Healthy Family and Multicultural Family Support during the COVID-19 pandemic. We used the job demand-resources model and the competing values model to categorize the four dimensions of organizational culture as a conceptual framework for this study. We found that the mean of work overload was higher than the means of job conflict and job ambiguity. Our latent profile analysis proposed four profiles of organizational culture: cultural absence type, authoritative culture type, middle cultural balance type, and high cultural balance type. The results of multiple regression analyses showed that work overload was positively associated with difficulties in new task performance and burnout, job ambiguity was positively related to burnout, and job conflict and ambiguity were negatively related to job satisfaction. These findings imply that the higher the job demands reported by family specialists, the higher the level of burnout and the lower the job satisfaction. In addition, organizational culture was a unique predictor of burnout and lower level of job satisfaction. Family specialists in the groups with a high cultural balance were Family specialists in the groups with a high cultural balance were more likely to have lower levels of burnout than those in the culture absence and in the middle culture balance, and higher job satisfaction than the other groups. The results suggest that management strategies to build a creative workplace culture can prevent burnout and improve job satisfaction.

Purpose: The purpose of this study was to investigate the relationship among nursing work environment, job embeddedness, and turnover intention in order to provide basic data for efficient management of human resources in nursing organizations. Methods: A cross-sectional, descriptive study design was conducted with 177 nurses who had worked for more than 6 months in five general hospitals on Jeju Island. A self-report questionnaire was used for data collection. Results: About 88% of the participants reported that they were considering a turnover plan because of overload in their jobs and poor salaries. Nursing work environment was significantly related to job embeddedness and turnover intention. Job embeddedness was significantly related to turnover intention. Hierarchical multiple regression analysis showed that factors affecting turnover intention were the organizational embeddedness factors of organization fit and organization sacrifice. Conclusion: The results indicate that nurses' turnover intention is associated with nursing work environment and job embeddedness. To reduce nurses' turnover intention and improve nurses' retention, nurse managers should improve the nursing work environment and consider job embeddedness, particularly in relation to the organization fit and sacrifice.
