In the competitive global market, innovation is vital to a firm’s longevity. To this end, organisations seek new and alternative ways to motivate employee innovation. This study examines the role of servant leadership as an antecedent to innovation. Drawing on the social identity model, this study examines the effect of servant leadership, team-member exchange (TMX) and perceived insider status on employee innovative behaviour. Primary data were collected from six manufacturing companies in Ghana. Using a sample of 213 employees and their immediate supervisors, a confirmatory factor analysis was conducted to test the discriminant validity of our measurement model. Hierarchical multiple regression was then used to determine direct and interaction effects, followed by bootstrapping tests to identify mediation and moderated mediation effects. The results showed that servant leadership and TMX are significantly related to perceived insider status. The bootstrapping indirect test and Sobel test demonstrated that perceived insider status mediates the relationship between servant leadership and innovative work behaviour. Moreover, the mediated relationship is only significant when TMX is low. This study empirically validated servant leadership as an antecedent to employee innovative behaviour. The findings demonstrated that perceived insider status is a mediating mechanism in this relationship, with TMX as its boundary condition.
This study examines psychological safety as a mediator in the relationship between Leader–Member Exchange (LMX) and voice behavior. Based on the conservation of resources theory, a moderated mediation framework was used to examine human capital investments, specifically employee education and tenure, as boundary conditions of this relationship. The research hypotheses were tested with a sample of 207 employee-supervisor dyads working in a time-lagged design. The study found that psychological safety is an intermediary mechanism through which LMX affects voice behavior. Employees’ level of education negatively moderates the relationship between LMX and psychological safety. Furthermore, the results suggest that organizational tenure accentuates the relationship between LMX and psychological safety, and strengthens the indirect effect of LMX on voice behavior. The theoretical contributions and managerial implications are discussed in addition to directions for future research.
This study examines the relationship between emotional exhaustion and job satisfaction. We further propose a safety climate and compensation as contextual variables that weaken the effect of emotional exhaustion. Survey data collected from 694 employees of a public hospital provided support for the hypothesized research model. The hierarchical multiple regression results reveal that high emotional exhaustion is negatively related to job satisfaction. In addition, the results suggest that compensation and a safety climate are moderating variables that mitigate the negative effects of emotional exhaustion. The theoretical implications and future directions are discussed.
PurposeWithin the theoretical frameworks of conservation of resources and job demands-resources (JD-R), the study aims to examine how sleep deficit could be negatively related to creativity at work by depleting critical resources of creativity.Design/methodology/approachThe survey data were collected from 368 individuals nested in 40 teams at a call center. The authors conducted multilevel analysis to test the proposed hypotheses to account for the hierarchical nature of the data while simultaneously estimating the effect of predictors at different levels on individual-level outcomes and maintaining the predictors' level of analysis.FindingsThrough the data, the study presents how the depletion of resource, that is, emotional exhaustion, functions as a mediating mechanism that connects sleep deficit to creativity at work. Further, the study presents that higher job demands can worsen the negative effects of resource depletion on creativity at work because they further deplete resources needed for creative behaviors. Specifically, when sleep-deprived, those working in a high-task-interdependence climate are likely to experience emotional exhaustion more severely than do those in a low-task-interdependence climate. Also, the relationship between emotional exhaustion and creativity is more negative for managers than for non-managers because of managers' higher job demands.Practical implicationsBy presenting sleep deficit-linked inhibitors of creativity at work, the authors highlight the importance of securing sufficient sleep and affective resources when designing jobs and HR practices in organizations.Originality/valueThis paper addresses the call for attention to examining the mechanisms through which sleep deficit affects employee creative behavior.
