Burnout and perceived work ability (PWA) are critical factors influencing teachers' professional well-being and effectiveness. The potential bidirectional relationship between these constructs remains underexplored, particularly in primary and lower secondary school teachers. This study examines the reciprocal relationship between burnout and PWA among teachers over time, using the job demands-resources (JD-R) model and the conservation of resources (COR) theory. A two-wave longitudinal study was conducted among 853 Czech primary and lower secondary school teachers. Data were collected via web-based questionnaires at two time points. Bayesian cross-lagged panel modeling (CLPM) was applied to analyze the bidirectional effects of burnout and PWA while controlling demographic variables. Burnout significantly predicted lower PWA, supporting the JD-R model's health impairment process. Contrary to expectations, higher PWA was associated with increased burnout, suggesting that PWA may not function as a protective factor in the teaching context, but rather as a risk factor increasing vulnerability to strain. Post hoc analyses indicated that burnout's detrimental influence on PWA emerged through several coherent facet-to-facet pathways, while in the reverse direction, only higher PWA in the teaching organization predicted later physical exhaustion. The study clarifies the directionality of associations between burnout and PWA, contributing to theory development and offering implications for interventions.

INTRODUCTION: This study investigates the antecedents of perceived teacher work ability, a critical construct for addressing challenges associated with extending working lives and maintaining sustained professional engagement in the teaching profession. Grounded in the job demands-resources (JD-R) model, this cross-sectional study investigates the relationships between job demands (quantitative, cognitive, and emotional), job resources (supervisor support, coworker support, and autonomy), burnout, and work-life conflict in shaping perceived teacher work ability. METHODS: Data were obtained from 841 Czech primary and lower secondary school teachers (86.1% female) with a mean age of 45.9 years (SD = 10.8). The full SEM model was developed and estimated based on the proposed hypotheses. RESULTS: The findings suggest that burnout is the most significant antecedent of perceived teacher work ability, with quantitative and emotional job demands indirectly influencing it through burnout. While supervisor and coworker support directly enhance perceived teacher work ability, autonomy primarily alleviates quantitative and emotional job demands, thereby indirectly mitigating burnout. Work-life conflict partially mediates the relationship between job demands and burnout but does not directly impact perceived teacher work ability. DISCUSSION: These results contribute to a deeper understanding of the interplay between job demands, job resources, and burnout in enhancing teachers' capacity to meet the multifaceted demands of their profession effectively.

Addressing the escalating prevalence of burnout syndrome, which affects individuals across various professions and domains, is becoming increasingly imperative due to its profound impact on personal and professional aspects of employees' lives. This paper explores the intersection of burnout syndrome and human resource management, recognizing employees as the primary assets of organizations. It emphasizes the growing importance of nurturing employee well-being, care, and work-life balance from a human resource management standpoint. Employing social media analysis, this study delves into Twitter-based discourse on burnout syndrome, categorizing communication into three distinct dimensions: individual, organizational, and environmental. This innovative approach provides fresh insights into interpreting burnout syndrome discourse through big data analysis within social network analysis. The methodology deployed in this study was predicated upon the enhanced Social Media Analysis based on Hashtag Research framework and frequency, topic and visual analysis were conducted. The investigation encompasses Twitter communication from January 1st, 2019, to July 31st, 2022, comprising a dataset of 190,770 tweets. Notably, the study identifies the most frequently used hashtags related to burnout syndrome, with #stress and #mentalhealth leading the discussion, followed closely by #selfcare, #wellbeing, and #healthcare. Moreover, a comprehensive analysis unveils seven predominant topics within the discourse on burnout syndrome: organization, healthcare, communication, stress and therapy, time, symptoms, and leadership. This study underscores the evolving landscape of burnout syndrome communication and its multifaceted implications for individuals, organizations, and the broader environment, shedding light on the pressing need for proactive interventions. In organizations at all levels of management, the concept of burnout should be included in the value philosophy of organizations and should focus on organizational aspects, working hours and work-life balance for a healthier working environment and well-being of employees at all levels of management.

The coronavirus disease 2019 (Covid-19) has created emerging mental health challenges around the world. Like other countries, Pakistan is also confronted with covid-19 calamities. The aim of the study is to examine the impacts of workplace measures (WM) on the job performance (JP) and covid-19 fears (CF) along with the moderating role of academic competence (AC) based on the organizational support theory (OST) and job demand and resources (JDR) theory. A quantitative approach was applied to collect data from 333 banking employees in Gujranwala (Pakistan), and the hypothesis were tested via structural equation modeling using SPSS and AMOS. The study findings indicate that workplace measures significantly affect covid-19 fears except for individual preventive measures (IPM). Similarly, workplace measures significantly impact on job performance apart from information about the pandemic (IAP). Moreover, academic competence insignificantly moderates between workplace measures and covid-19 fears, but a significant moderation is found between information about pandemic (IAP) and covid-19 fears. Meanwhile, academic competence significantly moderates between workplace measures and job performance instead of a relationship between information about pandemic and job performance. However, this study was limited only to the banking sector of Pakistan. So, it will open the doors for future researchers to investigate other cultural contexts and sectors. This research gives a holistic understanding of workplace measures and contributes to the body of knowledge by enlightening the moderating role of academic competence in the banking sector of Pakistan. These useful insights would enable practitioners and policy makers to develop more efficient strategies and workplace measures to enhance job performance and reduce the fears of covid-19 among employees.

OBJECTIVES: It has been reported that job demands affect sleep, but how different levels of job demands affect sleep remains unclear. We examined whether curvilinear relationships exist between job demands and multiple sleep health outcomes. DESIGN: Cross-sectional analyses with linear and quadratic effects, using self-administered survey data. SETTING: A national sample of US adults. PARTICIPANTS: Workers from Midlife in the United States Study (MIDUS2; n = 2927). MEASUREMENTS: The Job Content Questionnaire assessed overall and 5 specific aspects of job demands (intensity, role conflict, work overload, time pressure, and interruptions). Habitual sleep health patterns across 5 dimensions (regularity, satisfaction/quality, daytime alertness, efficiency, and duration) were assessed. Age, sex, race/ethnicity, marital/partnered status, education, job tenure, work hours, body mass index, smoking status, and study sample were covariates. RESULTS: There were significant linear and quadratic relationships between job demands and sleep outcomes. Specifically, the linear effects indicated that participants with higher job demands had worse sleep health, such as shorter duration, greater irregularity, greater inefficiency, and more sleep dissatisfaction. The quadratic effects, however, indicated that sleep regularity and efficiency outcomes were the best when participants' job demands were moderate rather than too low or too high. These effects were found for overall job demands as well as for specific aspects of job demands. Stratified analyses further revealed that these curvilinear associations were mainly driven by participants with low job control. CONCLUSIONS: Moderate levels of job demands, especially if combined with adequate job control, are related to optimal sleep health.

The aim of this study was to investigate the relationship between working conditions at the start of the COVID-19 pandemic (spring 2020) and employees' mental wellbeing. According to the Job Demands-Resources (JD-R) model, work intensification, increased difficulty in accomplishing work tasks, heightened risk of infection by COVID-19, and increasingly working from home may detrimentally relate to irritation. However, personal and job resources (e.g., occupational self-efficacy, social support) may buffer. Data from 680 employees from four European countries were analyzed by means of path analyses and polynomial regression. Work intensification was significantly positively associated with cognitive and affective irritation; other job demands were not. However, working from home prior to as well as during the pandemic was related to higher cognitive irritation. None of the moderators was of meaningful significance. Reducing work intensification as well as enduring home office seems to be crucial for interventions.
