I am working for a research organization where a senior member, holding a coordination role, John Doe, gives reference letters to people that he does not know well. It is a large organization and John has written tens of reference letters within the last year. Everyone seems to know this and accept it, it seems to be not John's modus operandi, but something that is expected from someone in his position.
When I asked letters to professors I worked with, they got calls from people interested on me and they got asked further questions about me. This makes me think that in order for someone to write a reference letter, that person needs to be well acquainted with the work of the person for whom the letter is.
I am not sure what is going on here. Is this a dishonesty case? Do I have a lack of understanding of what a reference letter is? Should I ask a letter from John, when he does not know me, despite John might be willing to write it on my behalf? Is this acceptable everywhere else in academia?
