This study aims to explore psychological safety as a potential moderating mechanism for the relation between functional diversity and individual perceptions of learning, and functional diversity and team performance in self-assembled teams.

To test these relationships, the authors conducted a cross-level, time-lagged, quasi-experiment, using a sample of 143 self-assembled teams. In one condition, participants formed into functionally diverse teams, and in another condition, participants formed functionally homogeneous teams.

Results suggest that functional diversity and psychological safety have an interactive effect on both individual learning and self-assembled team performance, albeit in different directions. Specifically, low psychological safety was more deleterious for individuals on functionally diverse teams than functionally homogeneous teams when it came to perceptions of learning, but the opposite was true when it came to team performance.

The results of this study indicate that it is critical to train team members on developing psychological safety, both in traditional and functionally diverse contexts.

This study examines the relationship between leader–member exchange (LMX) and employee discretionary work behaviors in terms of job crafting, innovative work behavior and knowledge-sharing behavior by focusing on the mediating role of psychological safety.

Multi-source and multi-wave data were collected from 284 employees in the banking sector of Pakistan.

The findings reveal a positive relationship between LMX and psychological safety. Psychological safety, in turn, is positively related to discretionary work behaviors (i.e. job crafting, innovative work behavior and knowledge-sharing behavior). Moreover, psychological safety fully mediates the relationship between LMX and discretionary work behaviors.

Drawing upon the conservation of resources (COR) theory, this study introduces psychological safety as a mediating mechanism in the relationship between LMX and three important discretionary work behaviors.

Drawing on social information processing theory (SIP), this paper examines whether and how humble leadership affects employees' service improvisation (ESI) in the hospitality industry. Further, the study investigates the mediating role of psychological safety and the moderating role of creative self-efficacy (CSE).

To test the proposed relationships, the study adopts a cross-sectional design, administering questionnaires to 456 frontline staff in Egypt’s hospitality industry across three main sectors: restaurants, hotels and travel agencies. SPSS 27 and AMOS 22 were used for statistical analysis.

The study reveals a positive relationship between humble leadership and ESI, partially mediated by psychological safety. Furthermore, CSE not only strengthens the relationship between psychological safety and ESI but also enhances the indirect effect of humble leadership on ESI via psychological safety.

The study offers valuable insights for practitioners in the hospitality industry. To boost ESI, organizations can incorporate humble leadership attributes into their leadership development programs. Fostering a psychologically safe workplace would facilitate the positive impact of humble leadership on ESI. Recognizing CSE as a pivotal moderator underscores the importance of strategically selecting and developing employees with high CSE. These insights aim to cultivate a more service-oriented and effective workforce in the hospitality industry.

This study significantly contributes to leadership research in the hospitality industry by uncovering a previously unexplored link between humble leadership and ESI. Exploring psychological safety as a mediator and CSE as a moderator enhances our comprehension of how and when humble leadership influences ESI.

This study aims to apply the affective events theory and psychological contract theory to investigate how job satisfaction and psychological safety mediate the effect of the behavioral integrity of supervisors on the organizational commitment of employees.

A questionnaire survey was conducted using purposive sampling. In total, 500 questionnaire copies were distributed, and 453 responses were collected, of which 441 were valid (valid response rate = 88.2%).

The behavioral integrity of supervisors has a direct negative effect on organizational commitment but significant positive effects on job satisfaction and psychological safety, and job satisfaction and psychological safety have significant positive effects on organizational commitment. Job satisfaction and psychological safety have significant mediating effects on the association between the behavioral integrity of supervisors and the organizational commitment of employees.

Leaders and top management should “practice what they preach,” integrate honesty into organizational culture through training and establish a code of conduct to ensure that employees uphold their commitments. Companies should establish appropriate disciplinary systems and norms related to work and other aspects of organizational culture; they should also establish fair, just and open assessment systems to minimize the gap between their employees’ actual and expected earnings.

This study is the first to simultaneously consider the mediating effects of job satisfaction and psychological safety on the association between behavioral integrity and organizational commitment.

This study examines the effect of the spiritual leadership of the leaders in a consulting team on psychological safety climate and team innovation. Moreover, our research adopts the contingency theory of leadership to investigate whether the effect of spiritual leadership on psychological safety climate and team innovation could be moderated by personal characteristics of team members in terms of occupational self-efficacy.

Survey data were obtained from 229 team members across 24 consulting firms in Bangkok. To minimize common method bias, team innovation was assessed by team leaders while other variables were assessed by team members. We used Partial Least Squares Structural Equation Modeling to analyze the data.

The analysis supports the positive effect of spiritual leadership on psychological safety climate and team innovation. Psychological safety climate also mediates the effect of spiritual leadership on team innovation. Lastly, the moderating effect analysis shows that the spiritual leadership of the team leaders exerts a weaker influence on the psychological safety climate and team innovation when team members exhibit high levels of occupational self-efficacy.

Because spiritual leadership plays a significant role in boosting team innovation through the creation of a psychologically safe climate, the consulting firms can provide a leadership development program to help their team leaders to gain insight into the nature of spiritual leadership and learn how to demonstrate appropriate behaviors when they supervise a team. In particular, this policy recommendation is highly relevant when team leaders supervise members who exhibit low occupational self-efficacy.

Our findings not only illustrate that spiritual leadership could enhance team innovation through the mediating role of psychological safety climate, but the level of occupational self-efficacy of the team members could significantly reduce the effects of spiritual leadership on psychological safety climate and team innovation.

To investigate the factors affecting innovation in Six Sigma improvement teams. Based on Activation Theory, this study explores the possibility of an inverted U-shaped association between psychological safety and innovation and examines how intrinsic motivation moderates this relationship.

Moderated regression analysis is carried out to test the curvilinear relationship, using data collected from 324 members of 102 Six Sigma improvement teams from two European manufacturing firms.

The findings demonstrate that the beneficial effect of psychological safety reaches an inflection point, after which its relations with innovation cease to be linear and positive; this gives the relationship a curvilinear pattern (inverted U-shaped). Further, intrinsic motivation has a supportive effect in enhancing the beneficial impact of psychological safety on innovation, and in shifting the inflection points to a higher level; this demonstrates their synergetic influence on innovation.

The impact of psychological safety on innovation is examined from the new perspective of a curvilinear relationship. This is one of the first studies to investigate the combined effects of individual (intrinsic motivation) and team-level antecedents (psychological safety) on innovation in Six Sigma teams. The study provides insights into how Six Sigma enhances innovation and offers some valid inputs to the current academic debate on this topic.

Mobile messaging groups (MMGs) have been widely adopted in construction practice, yet, little is known about how to foster knowledge sharing (KS) in MMGs, characterized by communication visibility. This study is thus motivated to investigate mechanisms for KS in this context.

The paper employs knowledge governance theory to construct a theoretical model and develop hypotheses. Specifically, psychological safety is identified as a mediator between knowledge governance mechanism (KGM) and KS, and promotion regulatory focus is identified as a moderator between KGM and psychological safety. Data from 208 Chinese construction project team members are collected to test the proposed theoretical model.

The results suggest that both formal and informal KGM positively affect psychological safety, which in turn improves KS (quantity and quality). Moreover, the mediating role of psychological safety is confirmed, and the moderating role of promotion regulatory focus is validated.

This study explores how to foster KS in MMGs, which are pervasive in today’s digital age. The findings in this study enhance the understanding of KS in digital environments and afford important insights into knowledge management within construction project teams.

The current study explores the role of social psychological factors on organizational commitment. It examined the relationships between organizational fairness, inclusion, diversity, sexism, psychological safety and affective commitment.

The study adopted a cross-sectional survey method where data were collected from staff across six higher education institutions in the United Kingdom. A total of 416 responses were collected and the data were analyzed by employing independent sample t-tests to explore gender differences regarding organizational diversity, inclusion, fairness, sexism, psychological safety and affective commitment. The mediating role of psychological safety in the effects of organizational diversity, fairness, inclusion and sexism on staff’s commitment to the organization was evaluated through a series of simple mediation models. Finally, the mediated effect of organizational social psychological factors on affective commitment through psychological safety, moderated by gender was tested.

As hypothesized, men had higher perceptions of organizational inclusion and diversity and viewed their organization as less sexist. Psychological safety mediated the positive effects of organizational diversity, fairness, inclusion and sexism on staff’s affective commitment to the organization. Organizational diversity and sexism played a bigger part in how women evaluate their organizational environment as safe to take risks and be themselves and consequently on how they commit to the organization. On the other hand, organizational fairness and inclusion seem more closely tied to men’s evaluation of their organization as safe to be themselves and consequently stronger commitment.

The findings shed light on the underlying mechanisms that shape affective commitment, that can lead to more inclusive work environments and contribute to systemic change in the Higher Education context.

Research focusing on psychological capital (PsyCap) has been mainly conducted at the individual level. However, recent research has expanded investigations to the collective level with a greater focus on team-level PsyCap. Although, as demonstrated by recent systematic reviews and meta-analyses, the relationships between individual-level PsyCap and the desirable/undesirable outcomes are fairly established in the literature, less is known about such relationships for team-level PsyCap. One of these important, yet least investigated, research areas is the research stream that focuses on the relationship between team-level PsyCap and the outcomes of health, Well-Being, and safety. This chapter aims to highlight the role of individual-level PsyCap as an important predictor of employees’ health, Well-Being, and safety outcomes, but also to go beyond that to provide insights into the potential role of team-level PsyCap in predicting such outcomes at both individual and team levels. To do so, the chapter first draws upon relevant theories to discuss the empirical research findings focusing on the relationship between individual-level PsyCap and the outcomes of health, Well-Being, and safety. It then focuses on team-level PsyCap from theoretical, conceptualization, and operationalization perspectives and provides insights into how team-level PsyCap might be related to health, Well-Being, and safety outcomes at both individual and team levels. Thus, this chapter proposes new research directions in an area of PsyCap that has been left unexplored.

The growing literature does not highlight the impact of high-performance work systems (HPWSs) on employee psychological well-being. This study aimed to test this influence by exploring the mediation of psychosocial safety and the moderation of supervisor support to overcome knowledge gaps in optimizing productivity in an increasingly dynamic workplace.

This study involved 395 service employees in Indonesia. Data were analyzed using the PROCESS macro approach.

The research findings indicate that while HPWS are perceived as organizational investments by employees, they do not directly impact employees’ psychological well-being in the service sector in Indonesia. Despite previous literature suggesting a positive relationship, this study emphasizes the importance of considering factors such as psychosocial safety and supervisor support in influencing employee perceptions.

This study extends the existing literature on the mechanisms of HPWS in promoting psychological well-being in the workplace. Furthermore, Psychological safety has also been identified as a strategic approach to reduce workplace bullying.

Organizations should prioritize creating a work environment that considers psychosocial safety and provides adequate supervisor support to enhance employees’ psychological well-being. Understanding the unique needs and perceptions of employees, including factors such as age and gender, is crucial in designing effective HPWS that foster a positive workplace culture and mitigate potential negative impacts.

The authors seek to explore the not yet fully understood relationship between HPWS, psychosocial safety, and supervisor support in promoting employee psychological well-being. This research also provides a broader view of how to prevent employees from feeling pressured and stressed in the workplace.
