Assessing the Mediating Effect of Team-Member Exchange on the Relationship between Transformational Leadership and Performance of People with Disabilities: A Study of Hong Kong Employers of People with Disabilities

Abstract

Purpose—This study aims to examine the links between transformational leadership, team-member exchange and job performance of people with disabilities in Hong Kong. Design/methodology/approach—Data were collected from a sample of 108 direct supervisors of people with disabilities via an online survey with validated scales. The structural equation modelling approach via SmartPLS (Version 3.0) was used to investigate the linear relations and the mediated effect amongst the variables. Findings—Transformational leadership was positively related to team-member exchange (p = 0.013), but its link with job performance was insignificant (p ≥ 0.05). Team-member exchange was positively related to job performance (p = 0.000). Hence, team-member exchange fully mediated the relationship between leaders’ transformational leadership and the job performance of people with disabilities. Originality/value—Transformational leadership is favorable for the job performance of people with disabilities, but its influence is indirect. High level of team-member exchange quality is necessary, as team-member exchange fully mediates the relationship between transformational leadership and the job performance of people with disabilities. Managers should demonstrate transformational leadership to all employees and not only pay attention to people with disabilities. This insight helps drive workplace disability inclusion.
