The head of my lab and I wrote a grant proposal together. Last year we submitted it with me and them as chief investigators. This year I wasn't allowed to submit grants per the rules of my government funding body, so I agreed to let my lab head submit the grant while listing themselves as chief investigator and removing me. However, in addition to this, my lab head added one of my colleagues as a chief investigator despite them not having written any of the grant. This was done without my permission.
My lab head added the colleague because the lab head believes it will look bad if they are a sole chief investigator. They believe adding the second chief investigator will make it appear as if they are supporting an early career scientist and that there is someone who will be managing the project day to day.
I don't feel comfortable about my lab head misattributing my grant proposal, particularly without my permission. Is what they're doing ethical? What can I do if I don't like it?
