ABSTRACT
It is inevitable that the leadership of a team, if it is associated with the right team development process, will have a positive impact on the results of performance and job satisfaction in the team. The purpose of this study was to examine the relationship between transformational leadership and the performance of the team, as well as the level of team job satisfaction, the degree which is mediated by levels of cognitive trust in the team leader and among team members, and the collective efficacy of the team. The study was conducted in 12 branches of PT. Bank Mandiri Tbk, Surabaya, with research conducted with 86 departmental office staff and 32 divisional supervisors or managers of these staff. Partial least squares (via SmartPLS 3.0) was used as a statistical research tool. Based on the test results, transformational leadership was shown to have a positive and significant impact on cognitive trust in the team leader and among team members; cognitive trust in the team leader had a positive, but not significant, impact on collective efficacy, but cognitive trust among team members had as positive and significant impact on collective efficacy. Collective efficacy had a positive and significant impact on both team performance and team job satisfaction. In addition, the results showed that cognitive trust in the team leader was not a mediating variable between transformational leadership and collective efficacy; however, there was a different result with cognitive trust among team members, which was a mediating variable between transformational leadership and collective efficacy.
