To be brief, I am a PhD student in the UK, and I have recently had some disagreement with the way my advisor handled our collaboration on research. This was initially a fairly minor thing. Not in the sense of what has happened, but minor in the sense that I only wanted to move past it, and to continue productively, but unfortunately he appeared to be too preoccupied, or for whatever reason, unable or unwilling to work together on correcting our results. Frustrating and not good for me, but ok, fine. At the time, no harsh words were exchanged at all, and there was some degree of understanding, although I was not happy with the mistake.
This has escalated beyond belief as soon as I relayed this problem to an administrative person, to explain there was a mutual mistake and I needed more time to submit. I explained the situation briefly to the person responsible for these things, made it clear I held no animosity or any interest in dwelling on it, and just needed some recovery time to move forwards. This was made totally clear to him and he was fine to shift the submission date and funding termination back slightly and he had agreed with me that there should be no blame here.
This has resulted in my advisor going on a furious rant at me in public, saying he refuses to work with me anymore. In private, the advisors have said that my 'complaints' have made the group look bad (no complaint was ever made, only a request for further time), and that they have now lodged some files or something on me with people at the university marking me as problematic. I have also been told that my complaints will make it difficult for me to get a job even after graduation, if I get to that point, because my advisor has no intention of giving me a reference, much less a positive one, and that they can make finding a job very difficult.
What on earth can I do? It seems that my career is now in ruins before it even started.
This whole situation has made me disgusted since it appears to have come almost out of nowhere, based on one conversation with an admin person. But I cannot work elsewhere if they follow through on their threats. How can I salvage my potential career?
Edit: There are just too many details I left out to edit down to size, and I would like to simply close this question or delete it if possible, due to confusion. I would prefer this to editing a popular question with too many specifics.
