Drawing on conservation of resources theory, this study aims to develop a resource-based model depicting a decreased level of psychological resourcefulness – relational energy, as a novel explanatory mechanism that accounts for the harm of abusive supervision, and we further investigate the role of leader humor as a boundary condition.

We applied multilevel path analysis to test our hypotheses with three-time-point survey data collected from 226 supervisor-employee dyads in a telecommunication company in China across six months.

Our results show that abusive supervision is negatively related to employee relational energy, leading to a subsequent decline in employee job performance. The predictions of the depleting effects get alleviated by leader humor.

This study foregrounds the importance of employee relationship management in the workplace and reveals that some abusive supervisors may manage to sustain employee performance and relational energy by using humor in their interactions, which necessitates immediate intervention.

These findings offer novel insights into the deleterious impact of abusive supervision by demonstrating the critical role of relational energy in dyadic interactions. We also reveal the potential dark side of leader humor in the context of abuse in the workplace.

This study was designed to contribute to the extant literature by discovering the perceptions of restaurant employees and managers toward equal opportunities in restaurant labor and working in a diversity-rich restaurant work environment.

A qualitative research approach was utilized. Through in-depth interviews, data were collected purposefully from restaurant workers in different positions (e.g. managers, servers, chefs and cooks) in the USA.

As a result of content analysis, different perspectives emerged on equal employment opportunity and diversity in restaurant labor. While some employees and managers believe that restaurant labor has equal employment opportunities, others think there is a lack of equal employment opportunity and partial equal employment opportunity in the industry. Most participants perceive working in a diversity-rich restaurant work environment as beneficial (an opportunity to learn about different cultures and an opportunity to learn different experiences and approaches).

To the best of our knowledge, this is the first paper to explore employees' and managers' perceptions of equal employment opportunity and diversity in the hospitality labor context, specifically restaurant labor. Therefore, the research findings will create value for scholars to understand the view on equal employment opportunity and diversity in restaurant labor. Further, it will assist practitioners in designing their labor structure regarding equal employment opportunity and diversity management for the future.

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.

Proposing a strengths-based perspective for innovative work behaviour (IWB), the purpose of this paper is to explore character strengths (CS) as antecedents to IWB. Extending the literature and operating in the framework of positive organisational behaviour, this paper considers creative self-efficacy a crucial link between CS and IWB. The role of growth mindset and learning organisation in facilitating IWB, presented as a conceptual model, contributes to the theory in this field, aiding in developing an overarching theory to understand IWB.

A narrative literature review was performed on the CS, IWB and positive organisational behaviour literature to adapt theories and develop propositions for the conceptual model.

This paper develops a conceptual framework proposing direct relationships between CS and IWB. This study posits creative self-efficacy (CSE) as the mediator between this relationship and growth mindset, learning organisation as the moderators for the link between CS and CSE and CSE and IWB.

The paper presents a conceptual framework focusing on the positive personality traits of employees, precisely their CS. This study explores how leveraging these strengths can enhance their capacity for IWB. The suggested model also prompts additional research in understanding IWB.

To the best of the authors’ knowledge, the conceptual framework proposed is the first to explore the diverse individual differences factors and the role of contextual facilitation in enhancing employees’ IWB. This study contributes to the growing field of positive organisational behaviour and assists HR managers in tapping into employees’ internal resources. This paper’s theoretical and practical discourse can inspire future research and encourage a strengths-based view of workplace processes.
