As an example let's take the University of Southampton, Malaysia branch. At face level, the university opened a branch in Malaysia because it's a symbiotic relationship: the university earns more revenue + spread its brand name, and Malaysia gets to leverage the university's expertise to train its future engineers + provide employment (administrators, academics, support staff, etc).
For the Malaysia branch to have some legitimacy, some of its staff must be from the main UK campus. From the branch's "our lecturers" page, this is indeed the case.
My question is, did these lecturers volunteer to go to Malaysia, or were they assigned by the university? Is it a good thing to be able to say one has worked in an overseas branch, or is it a distraction that must be endured for the sake of the university?
