My supervisor's relationship with me has been bad for over a year. Recently, I defended and she has been dragging out the process of me graduating. I basically feel that I am being held hostage in the meantime, since she has to sign off on my thesis revisions, which she has not. Today, I found out that one of my thesis chapters was submitted to a journal without my knowledge when she sent me reviewer comments on the paper and asked me to address them.

Now I've told my version of events for the early stuff to our graduate chair previously, and so it is not news to them that I'm basically being held over a barrel. They've agreed to step in if it seems like it is being dragged out anymore than it needs to be. I'm not sure what to do here though because if I report it, it seems like a high-stakes issue. From what I understand, submitting my work to a journal without my knowledge is an ethics violation. I worry that it will generate a larger conflict that I will be an unwitting participant in if I keep my graduate chair in the loop. On the one hand, it could strengthen my position that I'm being held against my will but on the other, it may drag everything out in a way that goes beyond just me, since it will be a more dangerous situation for my supervisor.

EDIT: CC'd grad chair in an email where I am cooperative but also voice my concerns about not being notified about my work being published. I suppose we will see if this escalates.
