Workplace safety has been a persistent issue for safety-critical organizations. Based on self-verification theory, this study investigates how authentic leadership affects safety behaviors in a collectivistic context.

This research collected 259 matching questionnaires for high-speed railway (HSR) drivers and their supervisors in China. Specifically, HSR drivers were invited to fill in their general perceived authentic leadership, person-organization fit and collectivistic orientation. In addition, their direct supervisors were invited to assess their safety behaviors.

Authentic leadership exhibits a significant positive impact on safety compliance and safety participation, implying that authentic leadership positively impacts safety behavior. The person-organization fit partially mediated the relationship between authentic leadership and safety behavior (safety compliance and participation). Furthermore, collectivistic orientation moderates the relationship between authentic leadership and person-organization fit.

The findings of this study provide important insights into authentic leadership and person-organization fit for developing effective strategies to improve workplace safety.

Working arrangements’ hybridity has become paramount, particularly after the coronavirus disease 2019 pandemic. A remote working environment has indubitable advantages (e.g. the ability to work from anywhere and at any time). However, such flexibility comes at the cost of being virtually always connected. This duality poses challenges for talent management (TM) in determining who can thrive under these specific conditions and how. This study explores how employees respond to this extended connectivity – namely, work connectivity behaviour after-hours (WCBA) – and its influence on proactive talent behaviour by constructing and testing a theoretical model that differentiates employees’ reactions to this condition.

This study collected data from 400 mainland Chinese employees using online and offline methods. Owing to the potentially varied effects of working in digital environments on employees, a dual mediation regression model was employed to test the hypotheses.

Remote and hybrid work and, specifically, the increased connectivity experienced by employees can be a “double-edged sword” in influencing their proactive behaviour (PB). While employees experience increased organisation-based self-esteem, which positively correlates with more intense PB, this prolonged exposure may also cause emotional exhaustion (EE), which has a negative correlation with PB. Jointly considering both mediation effects revealed that WCBA’s total effect on PB remained negative.

This study enriches the debate regarding the development of TM practices specifically designed for remote work. It recommends paying greater attention to how employees react to increased connectivity experienced in remote and hybrid working environments. Increased self-esteem or passive EE are possible elements for identifying employees’ talent potential. The separation between work and after-work is becoming blurred in the digital age, which reduces employees’ motivation and ability to exploit their inner talents. Therefore, organisations must find alternatives to preserve their talent pools. This study enriches theoretical research on WCBA, promoting an in-depth application of the theory of job-demand resources in the digital age.

Drawing on the equity theory and self-categorization theory, the authors examine the congruence effect of perceived self-overqualification and perceived coworker-overqualification on team–member exchange (TMX) quality, which in turn influences employees' organizational identification.

The data were collected from 392 employees in 78 teams at 2 time points, and polynomial regressions was used to test the hypothesized associations.

The more consistent perceived self-overqualification is with perceived coworker-overqualification, the higher quality of TMX. Moreover, TMX mediates the relationship between this congruence on organizational identification, which indicates that the congruence of perceived overqualification is related to higher-quality TMX, and then makes overqualified employees produce higher levels of organizational identification.

The findings of the research contributes to theory building of perceived overqualification through distinguishing perceived overqualification as an individual characteristic from the perception of overqualification that occurs in teams. Besides, by analyzing employees' experiences of overqualification in the context of their colleague-group, this study demonstrates the importance of considering overqualified individuals' social context (e.g. the composition of teams) in exploring the consequences of perceived overqualification. Theoretical and practical implications are discussed.

This paper aims to review the latest management developments across the globe and pinpoint practical implications from cutting-edge research and case studies.

The purpose of this paper is to combine triboelectric nanogeneration technology with ball bearing structure to achieve energy collection and fault monitoring.

In this paper, according to the rotation mode of ball bearings, the freestanding mode of triboelectric nanogeneration is selected to design and manufacture a novel triboelectric nanogeneration device Rolling Ball Triboelectric Nanogenerator (RB-TENG) which combines rotary energy collection with ball bearing fault self-sensing.

The 10,000s continuous operation experiment of the RB-TENG is carried out to verify its robustness. The accurate feedback relationship between the RB-TENG and rotation velocity can be demonstrated by the fitting comparison between the theoretical and experimental electrical signal periods at a certain time. By comparing the output electrical signals of the normal RB-TENG and the rotor spalling RB-TENG and polytetrafluoroethylene (PTFE) balls with different degrees of wear at 500 r/min, it can be concluded that the RB-TENG has an ideal monitoring effect on the radial clearance distance of bearings. The spalling fault test of the RB-TENG stator inner ring and rotor outer ring is carried out.

Through coupling experiments of rotor spalling fault of the RB-TENG and PTFE balls fault with different degrees of wear, it can be seen that when rotor spalling fault occurs, balls wear has a greater impact on the normal operation of the RB-TENG, and it is easier to identify. The fault self-sensing ability of the RB-TENG can be obtained, which is expected to provide an effective scheme for monitoring the radial wear clearance distance of ball bearings.
