I was awarded a rather prestigious postdoctoral fellowship that guarantees a generous salary, research expenses etc. for 2 years. It is in the same institution where I am working as a postdoc now, but would increase my salary by quite a bit and of course give me complete freedom over my research. I have not yet accepted the offer because I am struggling with a particular problem.
It is likely that in a year's time I will need to relocate to another country (for personal reasons). How bad is it to take the fellowship, knowing that there is a chance I will have to quit early? How frowned upon is quitting in the middle of a fellowship that explicitly specifies a 2-year tenure? Of course quitting a regular contracted postdoc job is straightforward, but I am not sure how it works with a personal fellowship—are there any additional consequences I haven't considered?
Edit: Just to provide some additional context, this is an individual fellowship (i.e. awarded directly to me) and the funding is internal (i.e. comes from the university itself).
