Literature on thesis supervision emphasises collaborative approaches with strong and supportive relationships. Despite an increasing research interest in supervisory relationships, little cross-cultural research has been conducted on supervisory roles and relationships in expanding-circle countries. This research explores how thesis supervisors negotiate different roles in supervision and relationships with colleagues and students in EAL (English as an Additional Language) contexts. A multi-case study was employed in three contexts: a Swedish university, two Indonesian private universities and an Indonesian public university. Semi-structured interviews were conducted with 14 thesis supervisors. Thematic analysis and systemic-functional appraisal theory were used to analyse the discourse. Our findings revealed that supervisors expressed dealing with (a)symmetrical relationships with students and colleagues, dealing with different roles as supervisors, and managing priorities relating to intellectual development and instrumental goals. However, these dimensions of supervision were described differently in the three contexts. Swedish supervisors expressed concerns about weak authority, while the Indonesian private supervisors described frustrated attempts to form a closer relationship with the students. However, the Indonesian public supervisors reacted to students trying to become too familiar. Furthermore, supervisors in the three contexts had to take different unwanted roles in supervision. Implications for the understanding of situated supervision are discussed.
