I recently returned from a conference at which I encountered the most contentious member of my dissertation committee. This fellow delayed my defense by 1) not reading my dissertation until the day before my originally scheduled defense date and 2) threatening to fail me if my defense date was not pushed back. My original defense date was cancelled the night before I was supposed to defend. This caused me to be a graduate student for an additional summer term. Because he was in Europe for the summer, he did not get around to reading the chapters of my dissertation relevant to his interests until late summer. This caused me to be a graduate student for an additional fall term. He did not actually read my revisions or my other chapters until late in the fall term, at which point I finally mustered the courage to say to him, enough is enough. I was allowed to defend late in the fall term, but lost a job as a result.
I count the interaction at this last conference as a win. Yes, he did approach me in a thinly veiled contentious manner, but I managed to avoid any private interaction for the most part. It is unfortunate that I have to do this, but one of my other committee members recommended this approach to him, complete avoidance in the profession, after my defense. I will not be able to avoid him completely, but I can certainly avoid any private interaction with him.
