ABSTRACT The Role of the English language in the Leadership Styles of Team Leaders in a BPO Industry Jean Andrea B. Ocampo Asst. Prof. Andrea Mae S. Baltazar Thesis Title: Author: Adviser: This study aimed to investigate the role of English, specifically illocutionary acts, in the leadership styles of team leaders working for a BPO company. This case study type of research included an inferential-descriptive approach to quantify the magnitude of the results and investigate what factors might be driving these outcomes. The qualitative method consists of interviews with team leaders. Meanwhile, meeting and coaching observation results and interview transcripts were analyzed to identify the connection between the leadership styles of tean leaders, their utilization of the English language, and the type of illocutionary acts they commit to. To identify the respondents' leadership styles, Blake and Mouton's (1964) leadership styles questionnaire was utilized. The study's findings show that the participants can lead a team regardless of their lack of expertise in the field and that one's level of education is not always a determining factor in one's advancement in a business process outsourcing company. The participants believed that their education and seminars received were essential to their leadership skills. Lastly, both participants were determined to be a "team leader" based on Blake and Mouton's (1964) study, but had differing illocutionary acts - participant 1 used more directive speech acts while participant 2 leaned more on representative speech acts. Hence, the language use of team leaders varies based on the length of their work and leadership experiences.
