Abstract
Purpose Drawing from social exchange theory, this paper aims to examine the role of five mediating mechanisms between the relationships of critical constructs of frontline employees' performance, and both transformational leadership and proactive personality to find out which mediating mechanism highly boosts frontline performance in 3-star hotels, Pakistan. Design/methodology/approach By testing parallel mediating linkages, this study used a structural equation modeling (SEM) technique using partial least square-SEM. This empirical investigation used a quota sampling technique to collect data from the frontline employees of 3-star hotels from the top five big cities of Pakistan. The study administered online survey questionnaires among 500 frontline workers in 3-star hotels. Findings The results of the study supported a substantial direct influence of transformational leadership and proactive personality on employees' performance. Nevertheless, it was observed in the findings of this investigation, significant mediating relationships between frontline employees' performance and the key constructs of transformational leadership and proactive personality. However, the construct of work engagement was not found to have a significant mediating relationship between front-line employees' performance and both constructs of transformational leadership and proactive personality. Moreover, leader-member exchange was identified as the highest mediating mechanism among the five. It is noteworthy, the results of this study highlighted that the notion of leader-member exchange is extremely embedded in transformational leadership to enhance the frontline performance than proactive personality. Practical implications The empirical evidence of this study insinuates that the management may establish a system of collaborative learning and social exchange between leaders and followers. This approach might be the essence to improve the work outcomes of frontline employees specifically within the 3-star hotels and hospitality organizations at large. Originality/value This study contributes to novel findings particularly to determine the five mediating mechanisms, i.e. work engagement, job satisfaction, organizational citizenship behavior, organizational commitment and leader-member exchange between frontline employees' performance and the constructs of transformational leadership and proactive personality. It might be noteworthy, the empirical and anecdotal pieces of evidence of this study indicated a social exchange system within transformational leadership optimizes the frontline employees' performance that ultimately contributes to the overall organizational outcomes.
