I'm a PhD student in the (probably) final third of my work, and I'm in the comfortable position that I have two options to continue my doctoral efforts for the next two years.
The problem is: the job offered by my supervisor is probably related to project work that has nothing to do with my dissertation. The other position is in another department of the university with another professor but fits very well thematically to my doctoral thesis.
What option could I choose here so that
- my supervisor is not embarrassed if I refuse his offer and
- my doctoral thesis is finished successfully and in time?
