Organizational justice is an important organizational-level resource that may facilitate employees' motivation and personal development. The aim of the current study is to test the indirect effect of organizational justice on job performance and happiness through two key psychological states: work engagement and burnout. Based on Job Demands-Resources theory, it was hypothesized that the organizational justice would be positively associated with job performance and happiness via increased work engagement and decreased burnout. In the study participated 216 employees, nested in 62 organizations. Multilevel analyses with MLwiN software revealed that organizational justice related positively and indirectly to both job performance and happiness through higher levels of work engagement. Furthermore, justice also exerted positive indirect effects on performance and happiness through its negative association with burnout. These findings suggest that organizational justice may initiate a motivational process that can enhance both work-related outcomes and personal well-being, supporting performance at work and flourishing beyond workplace.

Pharmacists are at high risk of infection due to their direct contact with potentially infected patients and customers during the COVID-19 pandemic. This study aimed to examine whether increased health issues among pharmacists during the pandemic were associated with pandemic-related changes in their work environment. A total of 438 pharmacists from 28 prefectures completed a self-administered survey between September 2021 and January 2022. Health issues with significant increases among pharmacists during the COVID-19 pandemic included depression, anxiety or emotional disorders, insomnia, eye problems and skin disorders. The following work-related factors were significantly associated with these health issues: For depression, anxiety, or emotional disorders, key factors were fear of infection during medication explanations to customers or patients and fear of infection related to work in general. Insomnia was significantly associated with shift adjustments and fear of infection when fatigued. Eye problems were linked to remote medication counseling via telephone or online platforms, disinfection and cleaning tasks, and shift adjustments. No significant work-related factors were associated with skin disorders. This study identified specific work-related tasks associated with increased health issues, offering valuable insights into the occupational risks faced by pharmacists and informing preparedness for future pandemics.

Working from home (WFH) is considered beneficial for sleep and fatigue recovery; however, it may vary according to chronotype. In this study, we aimed to assess the relationship between work style, sleep, and health, focusing on different chronotypes. A total of 1,114 workers completed an anonymous online survey, and 587 adult workers were included in the study. Changes in sleep and health indicators were compared by chronotype between the periods when participants worked at the workplace (WAW) every day and WFH two days or more a week. During the WFH period, sleep duration was longer and insomnia level was lower for all chronotypes than that during the WAW period. Evening chronotypes had higher risks of insomnia, poor mental health, and poor fatigue recovery during WAW than did morning chronotypes. However, regarding mental health impairment, the relationship by chronotype disappeared during the WFH period. WFH two days or more a week may provide benefits with respect to sleep and fatigue recovery, regardless of chronotype, particularly for mental health of evening chronotype; however, evening chronotypes had lower level of sleep and health than did other chronotypes, regardless of work style.

Victims of natural disasters require extensive medical, health, and welfare services. Disaster responders play a vital role in caring for victims but frequently face their own health problems. Responders may work despite physical or psychological distress (presenteeism), leading to many problems. We examined the association of activities and environmental factors with presenteeism in responders during the acute and subacute phases of recovery from the 2024 Noto Peninsula Earthquake (January 6 to March 31, 2024) using records from the Disaster Responder's Health Management version of J-SPEED. Presenteeism prevalence was 2.8% (acute phase: 3.5%; subacute phase: 2.1%). Unclear task and command (aOR=8.44, 95%CI: 5.49-13.00) and inability to take meals and breaks (aOR=8.92, 95%CI: 5.86-13.60) were associated with higher presenteeism odds. Support activities in the Health Emergency Operation Center (acute phase) and an unsafe work environment (subacute phase) were also significantly associated with presenteeism. The environmental determinants of presenteeism differed in the acute and subacute phases. However, potential confounding, including responder characteristics, could not be adjusted due to data limitations, so results should be interpreted cautiously. Nevertheless, improving the working conditions and implementing a comprehensive health management system for disaster responders, including pre-disaster training programs, may help mitigate their presenteeism.

This study examines the association of unmet healthcare needs (UHNs) with health-related productivity loss (HRPL), work ability, and work engagement among Korean workers. We analyzed 6,633 workers from two waves (August 2023 and September 2024) of the Korean Work, Sleep, and Health Study, a nationwide panel survey. UHNs were assessed based on self-reported experiences of forgoing necessary medical care. HRPL, work ability, and work engagement were measured using validated instruments. The generalized estimating equation models to repeated measurements applied to examine associations between UHNs and labor-related outcomes, adjusting for sociodemographic factors. Workers with UHNs had a 9.517 percentage point higher HRPL, 3.348-fold higher odds of poor work ability, and 1.506-fold higher odds of low work engagement compared with those without UHNs. Among causes of UHNs, financial constraints were associated with the largest increases in HRPL, poor work ability and low work engagement. These findings suggest that inadequate access to healthcare not only affects individual health but also has substantial implications for labor outcomes. Policy interventions to reduce UHNs, particularly for financially vulnerable workers, may improve both health and labor outcomes.

The global work environment is changing quickly, often becoming unfavourable to employees. This scoping review aimed to synthesise the existing literature on self-undermining behaviours in the workplace, with a particular focus on their development as a concept and their application in occupational contexts. The method followed was the guidelines of the PRISMA extension for scoping reviews (PRISMA-ScR). A search was conducted using electronic databases (e.g., ScienceDirect, Scopus, EBSCOhost) and online platforms (e.g., ResearchGate). The list of references from the included studies was also assessed for any additional papers that could be relevant. The review's inclusion criteria were as follows: studies published in peer-reviewed journals only in English that explored self-undermining. Of the 60 papers identified, eight studies with 4046 participants were included; the majority followed a quantitative method and a cross-sectional design. Self-undermining was positively associated with burnout and job demands. Self-undermining mediated the relationship between several work-related factors and outcomes. The studies in this review had limitations, e.g., self-reported data. Strategies to monitor and reduce self-undermining may be a crucial intervention to prevent burnout. Organisations shall develop and implement different programs to reduce these behaviours among employees.

This paper proposes a novel conceptual framework that integrates Disaster Risk Management (DRM) into Occupational Health Services (OHS) to improve resilience against technological hazards in high-risk industrial sectors. Even though OHS is meant to safeguard the workplace, it lacks systematic management for disaster risks such as chemical spills, industrial fires and toxic releases. To address this gap, the proposed framework synthesizes two internationally recognized models: the WHO's Health Emergency and Disaster Risk Management (Health-EDRM) strategy and the Basic Occupational Health Services (BOHS) model. The integration is structured across three interconnected pillars: (1) Risk Governance and Policy Alignment, (2) Proactive Risk Assessment and Preparedness, and (3) Emergency Response and Resilience-Building. This approach extends the scope of OHS from traditional hazard control and compliance to proactive disaster resilience, offering a new theoretical and practical model tailored for vulnerable and complex industrial environments. In doing so, the framework supports Sustainable Development Goals (SDGs) by enhancing worker protection, business continuity and community-level sustainability. It also lays the foundation for future empirical research and offers actionable guidance for industry leaders and policymakers.

The aim of this work is to identify occupational situations that are at risk and/or encourage alcohol use, whatever the type of consumption. This is a review of the literature in search of articles published between 1989 and August 2019, dealing with the effects of work situations on alcohol consumption. A qualitative analysis was conducted on the articles meeting the selection criteria, and the data were summarised based on the main risk factors identified. There is some evidence supporting work organisation as being at risk of alcohol consumption. This concerns mainly shift work and long-working hours, although the relation with drinking behaviours seems to be conflicting. Social relations and interactions within the workplace may induce (or be at risk of) alcohol consumption, particularly in the case of tolerant standards. The results regarding work stress are contradictory. Data regarding physical workload are scarce. Most studies addressed alcohol consumption as a public health issue, in the labour force, and not as an occupational health issue focused on work situations and conditions. Yet this knowledge may help the occupational physician to question the work environment, in order to prevent this risk on a collective technical level and on an individual case-by-case basis.

The relationship between the employment status and mental health is well established, yet the behavioural mechanisms underlying this association across age groups remain unclear. This study investigates whether artistic leisure moderates the association between employment status and mental health, measured with the 12-item Chinese Health Questionnaire (CHQ-12), using nationally representative survey data from Taiwanese adults aged 18 and above. Participants were categorised into three groups. Descriptive statistics summarised mental health prevalence, and χ² tests assessed associations across age groups. Hierarchical multivariable logistic regression, adjusted for sociodemographic factors, religious affiliation, financial sufficiency, and physical health, was employed to examine the relationship. The prevalence of good mental health was highest among older adults (84.83%), followed by young (79.25%) and middle-aged adults (78.76%). Artistic leisure significantly moderated the association between employment and mental health in young adults, with those in employment who engaged in artistic activities reporting better outcomes (AOR=4.22, 95% CI: 1.98-8.96). No significant moderating association was found in the older age groups. These findings suggest that employment plays a critical role in the mental well-being of young adults, highlighting the importance of understanding the contexts and motivations behind their engagement in artistic leisure.

Fatigue is a longstanding issue in air traffic control (ATC), closely associated with shift work and time-related factors. However, the dynamics of fatigue across morning, evening, and night shifts in an area control center (ACC) remain largely underexplored. This study examined sleep duration and fatigue progression across different shift types. Both objective (three-minute Psychomotor Vigilance Task, PVT-B) and subjective (Stanford Sleepiness Scale, SSS) measures were conducted at the beginning, middle, and end of each shift. Results indicated that pre-shift sleep duration was shortest before night shifts, likely increasing sleep pressure and reducing alertness during the window of circadian low (WOCL). Subjective fatigue remained stable throughout morning shifts but increased towards the end of evening shifts, reflecting circadian influences. Night shifts exhibited peak fatigue during the WOCL, driven primarily by circadian rhythms rather than task load. Objective measures revealed a mid-shift decline in performance, with only partial recovery in the latter half of night shifts. Compared to day shifts, night shifts resulted in significantly higher fatigue levels, underscoring the critical role of circadian rhythms in fatigue dynamics. These findings highlight the need for targeted fatigue mitigation strategies that address circadian vulnerabilities and irregular sleep patterns in ATC shift systems.
