I recently started (last week) a post-doc position and I have a submitted paper which got an R&R before finishing my Ph.D and having this post-doc position. I will resubmit the paper this week and my current director says that I should change the affiliation on the revised version of the paper and mention that the paper is financially supported by the institution where I am a post-doctoral fellow.
I wonder if it is correct and ethical to change the affiliation because 99,9% of the work has been done under the financial support of the institution where I have done my Ph.D.
