I want to check if the following case is considered plagiarism or at least unethical.
Four years ago, I wrote a personal grant proposal for a PhD scholarship. It was written entirely by me in my own personal time. I sent it to a professor, who read it and gave some minor remarks. He agreed to become my promoter if I receive the grant. I got the grant and carried out the research under the guidance of said professor.
It now came to my attention that our research unit has recently received a grant for similar research. I read the proposal, and about half of it is verbatim copied out of my original proposal. No permission was asked from me.
To me, this feels very wrong. What are your opinions?
