Background:Though the COVID-19 pandemic recedes,and our society gradually returns to normal,Chinese people’s work and lifestyles are still influenced by the“pandemic aftermath”.In the post-pandemic era,employees may feel uncertainty at work due to the changed organizational operations and management and perceive the external environment to be more dynamic.Both these perceptions may increase employees’negative emotions and contribute to conflicts between work and life.Drawing from the ego depletion theory,this study aimed to examine the impact of job insecurity during the post-pandemic era on employees’work-life conflicts,and the mediating effect of workplace anxiety in this relationship.Besides,this study also considered the uncertainty of the external macro environment as a boundary condition on the direct and indirect relationship between job insecurity and work-life conflicts.Methods:A two-wave questionnaire survey was conducted from October to December 2023 to collect data.MBA students and graduates from business school with full-time jobs are invited to report their perception of job insecurity,work anxiety,perceived environment uncertainty,and work-life conflict.This resulted in 253 valid responses.Data analysis was performed using the SPSS,Amos,and PROCESS.Results:The results showed that:(1)Employees’job insecurity would directly intensify the work-life conflict(B=0.275,p<0.001,95%CI[0.182,0.367]).(2)Employees’workplace anxiety mediates the relationship between job insecurity and work-life conflict(B=0.083,p<0.001,95%CI[0.047,0.130]).(3)The mediating effect of workplace anxiety between job insecurity and work-life conflict exists when perceived environmental uncertainty is high(B=0.049,95%CI[0.011,0.114]),while vanishes when perceived environmental uncertainty is low(B=0.024,95%CI[−0.005,0.068]).Conclusion:Job insecurity combined with perceived environmental uncertainty in the postpandemic era fuels employees’workplace anxiety and work-life conflicts.Post-pandemic trauma lingers,necessitating urgent attention and response. 展开更多

Why are there so few women in corpomtive top ranks? Is it possible that prejudice and sexism work selectively, allowing women to ascend not beyond a certain point in corporate hierarchy? This paper rejects such a perspective and aims at understanding the dynamics that drive women against the executive suite. The premise beneath this research is that women are not victims, but autonomous individuals. In order to test the hypothesis of Brazilian women choosing not to ascend, the first step was to analyze Brazilian Institute of Geography and Statistics' (IBGE) data on work force and employment. Thereafter, the research explores the possibility that organizational dynamics is a major factor for women to deal with work-life issues. Studies of scientific organizations show that flexibility helps conciliate work and life. The conclusion is: if corporations could emulate the scientific organizational environment, probably they would not only attract more women to the executive suite, but also adapt to a transforming society. 展开更多

Objective: This study investigated the mediating effect of cultural competence in the relationship between person-job (P-J) fit and work-life balance among female nurses. Methods: Participants included 216 (mean age = 31.12;SD = 9.16) female nurses that were conveniently selected from two Federal Teaching hospitals in Nigeria. Three questionnaires via the perceived fit scale, cultural competence scale, and work-life balance scale were utilized for data collection. Data were analyzed using both the Pearson Product Moment Correlation and PROCESS macro statistical tools. Results: Results revealed that both P-J fit and cultural competence positively and significantly associated with work-life balance. Also, cultural competence partially mediated the relationship between P-J fit and work-life balance of nurses. Conclusions: The cultural competence enhances the capacity of nurses to balance work and family roles. Therefore, cultural competence training that enhances nurses’ capabilities to handle cultural diversities of patients is essential. 展开更多

Findings of this study can be summarized as follows. First, the hypothesis that the wages and working hours have positive but differential effects depending on wage level categories are supported. Second, effects of cultural factors, such as workaholism and consumerism, on long work hours, however, are not significant in both countries. Third, for Korean manual workers, the probability of working long hours is high, but the level of time scarcity is low; but the effect of union membership on long work hours is not significant in both Korea and Japan. Fourth, the hypothesis that negative effects of long work hours and time scarcity on satisfaction with work-life balance are supported. These findings suggest that an increase in wage for non-regular workers and a minimum wage are required to reduce working hours. In addition, they also suggest that reducing working hours, overtime work in particular, and wage gap are crucial to raising the level of satisfaction with work-life balance in both Korea and Japan. 展开更多

This research aims to explore the major determinants of work-life balance(WLB)for university student workers in Lebanon.The proposed relationships consist of causality between each of the variables of working hours,proximity to employment,proximity to university,workload,study leave,leaving early,work from home,study at work,and flexible working hours on one hand,and work-life balance on the other.Employing a deductive approach,this study presents one main research question and quantitatively tests 11 hypotheses using a sample of 300 workers studying in both Lebanese University and Notre Dame University.The findings show that work-life balance significantly varies according to demographic factors.As for variables,the number of courses was found to have a significant negative causal relation with work-life balance,while the ability to obtain a study leave and leaving early have a significant positive causal relation with work-life balance.This research adds quantitative empirical proof that number of courses,study leave,leaving early significantly affect“work-life balance”of today’s private and public university student workers in Lebanon.Therefore,the findings offer a theoretical enrichment to the topic of work-life balance in general,and open way for new research to expand internationally as well as locally. 展开更多

Social media technologies have made it increasingly feasible for employees to be connected to work. WeChat, a newly emerging social media platform, is widely used in daily life, yet there is still little understanding of the consequences of the use of WeChat groups in enterprise. Based on boundary theory, we suggested that the use of WeChat groups in enterprise have both pros and cons for employees. We gathered data from an online survey of 202 employees. Results show that posting work-related content in enterprise WeChat groups had a beneficial impact on work for employees but also caused work-life conflict (WLC). However, posting life-related content in enterprise WeChat groups contributes to employees' life-work enhancement (LWE). Contributions and future study directions of these findings are discussed. 展开更多
