The purpose of this paper is to examine how employee engagement and affective commitment mediate the relationship between transformational leadership and voluntary turnover intention. The study also investigates the moderating role of psychological climate in the relationship between affective organisational commitment and voluntary turnover intention.

This study employed a cross-sectional design as its framework. In addition, hierarchical linear modelling with bootstrapping analysis was conducted using data from a sample of 336 employees in a large public sector organisation in Ghana.

The results showed that transformational leadership positively influenced engagement, which was then negatively related to employee turnover intention. Furthermore, employee engagement was found to mediate the link between transformational leadership and affective organisational commitment, whereas both employee engagement and affective organisational commitment were found to mediate the link between transformational leadership and voluntary turnover intention. Finally, psychological climate was found to moderate the link between affective commitment and voluntary turnover intention.

Despite the practical significance of this study in lessening the turnover decision of employees, the study has some limitations. Most significantly, the sample size of this cross-sectional study was small and limited to employees from only one large public sector organisation in Ghana. Findings of this study could be generalised by using large samples from other sectors and geographical areas. Furthermore, future studies should consider positive outcomes such as OCB and innovative work behaviour to help extend our conceptual framework.

Overall, findings of this study provide tentative support to the proposition that employee engagement and affective commitment help to minimise the decision of employees to leave the organisation regardless of how they perceive the leadership style of their immediate supervisors. Most importantly, psychological climate which is referred to as individual employee perceptions of their work environment had a strong contingent effect on the negative relationship between affective commitment and turnover intention such that employees’ positive perception of the work environment weakens the link between commitment and turnover, whereas a negative perception of the working environment strengthens the relationship between commitment and turnover. As a result, employees’ positive perception of their work environment decreased their turnover intention decisions.

The purpose of this paper is to examine simultaneously multiple mediating mechanisms through which transformational leadership affects innovative work behaviour (IWB). Specifically, the authors test job autonomy, affective commitment and supportive management as the three mediating paths through which transformational leadership predicts innovative wok behaviour.

Data were collected from 358 employees working in large retail banks in Accra, the capital of Ghana. A partial least squares structural equation modelling technique was used to estimate the measurement and structural models.

Job autonomy and supportive management rather than affective commitment mediated the relationship between transformational leadership and IWB. In addition, transformational leadership positively relates to job autonomy, affective commitment, supportive management and IWB.

By adopting leadership behaviours that seek to offer employees freedom on the job, a feeling of attachment to the organisation and positive perception of leadership support, managers and HR professionals can potentially foster employee innovation. This could stimulate organisational innovation and business success in the financial sector.

Although it is important to understand the mechanisms or processes through which transformational leadership behaviour promotes IWB, research in this area is scanty and scarce. This study theorises and empirically examines job autonomy and support management as novel mechanisms through which transformational leadership behaviour translates into workers’ innovative behaviour in formal banking institutions.

The purpose of this paper is to investigate the impact of transformational leadership on employee turnover intention through the mediating role of affective commitment.

The study examines conceptual relationships in the Ghanaian context, based on structural equation modelling with maximum likelihood estimation, using sample employees from the private sector organizations. In addition, the mediation analysis is conducted with Sobel’s test and 95 per cent CI bootstrap analysis.

The study shows that affective commitment would decline workers’ quitting intention and serves to promote a degree of trust and willingness to follow their leaders’ philosophy, ideology, vision and guidance in the organization. Hence, affective commitment fully mediates the relationship between transformational leadership and employee turnover intention.

To help lessen employees quitting intentions, both middle and top-level managers should endeavour to create an atmosphere of trust, admiration, loyalty and respect for their employees.

Overall it is shown that affective commitment was the mechanism through which transformational leadership influences employees’ turnover intentions in the SLCs in Ghana.
