This study aims to examine the scientific publications related to leadership research in hospitality from 2000 to 2021 by conducting a systematic review (qualitative) and to discuss implications for future research.

For the qualitative approach, the authors conduct an in-depth critique of major leadership theories using 167 articles indexed in the Web of Science Core Collection.

The findings show that transformational leadership, leader–member exchange and servant leadership are the most prominent leadership topics studied from 2000 to 2021, followed by abusive supervision, empowering leadership, ethical leadership and authentic leadership. A framework is presented highlighting the mediators, moderators, outcomes, sample and research designs used in each of these lines of leadership research. Moreover, 16 areas for further research are identified and discussed.

This review uncovers scholars’ general lack of regard for how the study of leadership might benefit from examining hospitality as a special and challenging context for leadership and business performance.

This study reviews and critically analyzes leadership research in hospitality using qualitative methods. Therefore, the authors believe this review is of great value to academics and practitioners because it synthesizes and analyzes the field and identifies important research opportunities.

Building on the theories of social learning and social information processing, this paper aims to examine the effect of green servant leadership (GSL) on green voice behavior among staff working in Qatari higher education. In this relationship, the climate for green initiative (CFGI) was used to act as a mediating mechanism.

Data in this study were collected from 275 staff working in Qatari higher education. Structural equation modeling was used to analyze the data.

The results suggest that GSL positively influences green voice behavior, whereas CFGI mediated this link.

The results can be beneficial to higher education pertaining to the importance of GSL in generating positive green behaviors such as green voice behavior. Furthermore, the results highlight the significant role CFGI plays in motivating such behaviors.

To the best of the authors’ knowledge, this is the first study that examines the link between GSL and green voice behavior in the higher education context. Furthermore, research on CFGI has received limited attention so far.

Although decades of research on transformational leadership have resulted in a firm understanding of its consequences, the impact of environmental-conscious transformational leader on positive employee outcomes and underlying mechanism in environmental leadership–outcome relationship is not well examined. This study aims to examine a moderated mediation model of effects of environmental consciousness (EC) on the mediating role of perceived corporate social responsibility (PCSR) in transformational leadership (ETFL) and pro-environmental behavior (PEB) relationship in energy-intensive industries.

In total, 320 self- reported questionnaires were collected from employees working in different Indian organizations across different sectors. All measures used in this survey were adopted from well-established scales. To minimize the effects of common method variance arising, the survey questionnaires were administered to the participants in two stages (with a gap of 14 days), with antecedents separated from outcomes. Partial least squares (PLS) structural equation modeling and SPSS-process macro were applied for testing the hypothesized model.

The results revealed that ETFL positively correlated with PEB. The hypothesized moderated mediation condition was supported as the results suggest that PCSR mediated the ETFL–PEB relationship, and EC moderated this mediating pathway; i.e. indirect effects of ETFL on employee PEB via PCSR were stronger for employees with high EC.

In particular, this research provides implications for training and development of leaders. The study indicates the importance of environmental-conscious leaders in enhancing perceived PCSR and PEB of employees. Likewise, the finding found that PCSR mediates the ETFL and PEB relationship. Moreover, the indirect effect of ETFL on PEB through PCSR moderated by EC highlights the importance of managing and ensuring effective leader–employee relationship that facilitates ecofriendly initiatives.

The study is based on the data collected from energy-intensive industries. Thus, it provides insights into the role and importance of green leadership and green behavior in energy industries. It is one of the few studies in the energy-intensive industry in India that help the researcher to delve into future research on the same.

The purpose of this study is to examine the extent to which promoting sense of community moderates the relationship between servant leadership style and socially responsible leadership (SRL) of public universities in Uganda.

The study adopted cross-sectional survey design to collect data at one point in time using self-administered questionnaires from 214 respondents to examine the relationship between servant leadership and socially responsible leadership with promoting sense of community as a moderator. The study used statistical package for social scientists (SPSS) PROCESS MACRO to establish clusters among the surveyed public universities and later a model was derived.

The study found a significant moderating effect of promoting sense of community on servant leadership and socially responsible leadership. Implying that investment in promoting sense of community creates awareness about the socially responsible leadership in public universities.

Managers of public universities need to pay keen interest in promoting sense of community to boost socially responsible leadership by building a strong servant leadership style through promoting sense of community for senior managers and leaders especially heads of departments, faculty deans and principals in public universities.

This study contributes to socially responsible leadership literature by advancing the idea that SRL is an important resource that enhances through instituting servant leadership and promoting sense of community in a complex environment. Ideally, servant leadership and promoting sense of community is one of the drivers of customer value, efficiency and effectiveness of public universities.

This study aimed to develop an in-depth understanding of the outcomes of servant leadership at the team and organizational levels. It reviews the relationship between servant leadership and its team- and organizational-level outcomes, and examines the mediation and moderation effect of the relationship. It further identifies the mechanism by which servant leadership is beneficial to the organization.

A systematic literature review is conducted, focused on 52 articles published between 2012 and 2022. Content analysis and descriptive analysis were used to respond to the research questions.

A new conceptual model was developed to better understand the outcomes, mediators and moderators of servant leadership at team and organization level.

Future research should further explore outcomes of servant leadership at team and organizational levels and test how mediators affect the relationship between servant leadership and associated outcomes.

This study provides a framework for leaders on how servant leadership contributes to teams and organizations, and how a leader applies servant leadership.

This systematic review presents a new model that builds on existing research into servant leadership and its impact on team and organizational levels completed in the past decade. To date, there have been no reviews of servant leadership that focus only on outcomes at the team and organizational levels using a widely recognized database.

Based on social exchange and social learning theories, this study explicates the mediating role of individual-level human capital, structural capital and relational capital in linking servant leadership with the innovative work behavior (IWB) of employees.

Data were collected from 256 manager–employee dyads from the IT sector of Pakistan in three phases through a survey conducted two months apart.

Results showed that two dimensions of individual-level intellectual capital, namely, individual-level human capital and individual-level relational capital, mediated the relationship between servant leadership and IWB, whereas individual-level structural capital did not mediate the relationship between the two variables.

This study confirms the relationship between servant leadership and IWB and tests the mediating role of the three facets of individual-level intellectual capital in linking servant leadership with the IWB of employees.

This study investigates the link between servant leadership and project management effectiveness in developmental projects in non-governmental organisations (NGOs). Further, this study examined the mediating role of conflict resolution and moderating role of organisational culture.

A three-wave survey of 288 non-governmental organisation (NGO) employees was used to evaluate the hypotheses. Hierarchical regression analysis and Hayes' PROCESS macro technique were used for data analysis.

In this study, servant leadership positively affects employee project management effectiveness in developmental projects in NGOs, and conflict resolution mediates the relationship. Furthermore, the results show that organisational culture moderates the positive relationship between servant leadership and employee project management effectiveness. Moreover, the authors investigated the hypotheses via a moderation mediation model. The strength of the mediated link between servant leadership and project management effectiveness (via conflict resolution) depends on organisational culture strength.

Leaders that practice servant leadership care for their employees genuinely and serve them by allowing them to make their own decisions. Every organisation may benefit from this leadership style since it encourages project effectiveness

New empirical data from this study suggests that servant leadership positively and substantially affects employee project management effectiveness in developmental projects in NGOs.

Based on the social exchange theory, the aim of the present study is to examine the effects, both direct and indirect (through sustainability-oriented innovative behaviors [SIBs]), of sustainable project leadership (SPL) on sustainable project performance (SPP). Project management approaches (PMAs) (traditional, hybrid and agile) were examined as conditional factors in the “SPL–SIBs” relationship.

The study employs structural equation modeling based on data collected from 197 software engineering project team members working in the financial industry in Poland.

The study revealed that SPL significantly, positively affected SPP. It also provided evidence for the significant mediating impact of SIBs in the relationship between SPL and SPP and the conditional effect of agile and hybrid PMAs on the “SPL–SIBs” relationship.

The novelty of this work lies in introducing sustainable leadership into project management research, proposing and testing a unique and complex research framework, designing valid scales for measuring SPL and SPP, and suggesting many theoretical and empirical implications.

The purpose is to use co-citation analysis of servant leadership (SL) research to investigate the evolution of the field, its subfields, gaps and opportunities for future research in a systematic manner.

A document co-citation technique and three clustering algorithms (latent semantic index (LSI), the log-likelihood ratio (LLR) and the mutual information (MI) index) were employed to analyse 24,030 references from 549 articles spanning a period of 50 years.

Cluster analyses reveal that SL research consists of eight distinct subfields: (1) conceptualisation and measurement of SL; (2) SL and related theories; (3) methodological foundations and empirical expansion of SL research; (4) individual-level cognitive effects of SL and related theories; (5) “Warmth effects” of leadership behaviour; (6) antecedents of effective leadership; (7) SL, marketing, sales management and ethics and (8) SL, job design and work engagement. Important gaps and opportunities for future research are identified.

The analyses do not show a complete picture of research on SL. Interesting works used by subgroups of SL researchers may not have enough citations to be included in the results. Moreover, bibliometric analyses do not explain the impact of books, journals and articles on the practice of SL. The authors welcome future analyses of the most influential sources of SL practice. The authors expect that managerial and practice-oriented books and journals, such as the International Journal of Servant Leadership and the Servant Leadership Theory and Practice, would play a central role in such analyses.

The discussions of the nature of SL, its effects and antecedents are useful to leaders who want to develop a SL style or assist others in developing it. For researchers and doctoral students, the cluster analyses of co-citations give an overview of the subfields of SL research and reveal important knowledge gaps in the literature.

SL has several favourable effects on the motivation and psychological well-being of followers. Also, followers tend to adopt a willingness to serve.

Previous research has categorised SL research into three broad categories or phases. The cluster analyses of the co-citations reported here reveal a meaningful structure of eight distinct subfields. Knowledge gaps within the subfields represent novel opportunities for future research on SL. The authors also suggest a new subfield of SL research: pedagogical approaches to the motivation and development of SL skills.

Anchored in the conservation of resources (COR) theory, this research aims to examine the effect of spiritual leadership on green creativity via the mediating role of green work engagement (GWEN).

The data were collected from 254 frontline hotel employees in the United Arab Emirates (UAE), and the hypothesized relationships were assessed using partial least squares structural equation modeling (PLS SEM).

The findings suggest that spiritual leadership boosts GWEN and green creativity, and GWEN positively affects green creativity and mediates the nexus between spiritual leadership and green creativity.

Top management in the hospitality industry should focus on building spirituality and spiritual practices among their managers to accomplish organizational green goals. The hospitality industry is a highly competitive service sector that contains several unique challenges for workers, such as growing customer demands and asking for employee creativity while concurrently producing and delivering high-quality, differentiated services. In such tense and demanding professional settings, employees require intrinsic motivation to achieve something “out of the box.” Organizations should understand that intrinsic motivation implanted by spiritual leaders can encourage individuals to engage in green tasks and ultimately go beyond the script to achieve green creativity.

This study advances the extant literature by highlighting the role of spiritual leadership, as an emerging leadership style, in fostering GWEN and green creativity. It also adds to the existing research by examining the underlying mechanism through which spiritual leadership nurtures green creativity.
