I just RE today, well, at least for a couple of months before school starts. I wouldn't say it was the best decision from a purely financial point of view, but I have finally decided that the BS just isn't worth the money. All of my reasonable proposals were denied, so I figure, hey, if you the management want to look out only for your own interest, then I need to start looking out for mine. I simply don't see why I need to work my butt off until July, put my move and transition plans on hold, just so that I may or may not get my pension, so I bought myself two months of no-BS R&R and study time by leaving early. I just had a great 4-day weekend during which I helped a friend move, attended a family reunion, and emceed a wedding. I had a blast, and I didn't have worry whether I will have to get up early on Monday. Of course, I'll have to look for another job after school, but this current experience is good practice on how and when to walk out the door.
See this thread if you don't know know what I'm talking about:
