Manager is blocking advancement - should I go?

Hi - here's the problem: I recently posted for a clinical leader position for which I was qualified. I was encouraged by colleagues and supervisors to apply. My floor manager did not agree and after much (painful) discussions it was revealed that she has a "personality clash" with me. The reasons she gave were trivial and not based on my experience or past performance. I am concerned now about repercussions but have worked on this floor in a charge role for 7 years. I have always received excellent performance reviews in the past but am nervous about what is to come. Do I cut my losses and transfer to another unit? Has anyone had a similar issue and how did you address it? Thanks for any help you can provide.
I would transfer.
Talk to your HR department. They get paid to sort out this type of situation. If your performance reviews are all good, there is no way your promotion should be impacted because of a 'personality' issue.
That's the thing - I did talk to both my union and the executive director of HR. It seems my only recourse now is to file a grievance...which is not how I want to get a job. There seems to be a culture of protecting management at all cost...very frustrating. I have gone up against my boss, the Assistant V.P. of Nursing and the V.P. of Nursing. They have all offered me "training for emerging leaders" despite the admission of personal issues on my manager's part. It's insane. I feel like I'm crazy at this point and that maybe I shouldn't have spoken up for myself. On my better days, I know if I had to do it again...I would do the exact same thing. You can't just advocate for your patients - you'd better be prepared to advocate for yourself as well.I think it's time for a transfer....
I hope by now you have gotten out of there. I have been in the same situation myself, and let me tell you, it does not improve with time. The Manager always seems to be the winner depending on how many letters are behind her name. That's all management cares about. My suggestion is to find something else, and best of luck to you.
