The number one reason I'm punching at the first available opportunity.
I've always loved the idea of serving my country and I'll admit patriotism is the reason I joined in the first place, but like it's been said so many times on this site before... patriotism only goes so far. I'm sick of: learning how to do other people's jobs (we all should have like 15 duty badges), learning 100 different office jobs, getting assigned 10,000 additional duties, being denied time to focus on my primary job (which I thought was flying), getting lectured about SOS in correspondence to do SOS in residence, constantly being told by everyone and their mother to take some time to start my masters (even though I'm almost done... good job knowing what your people are doing), being told I'm a piece of sh*t for not volunteering enough, being made to feel like a criminal because I'm not getting 100's on the stupid f'ing PT test, being made to feel like a criminal in general through all of the sexual harassment/equal opportunity/DADT/You're-a-flyer-therefore-I-hate-you briefings that we get, being "Chief'd" (most of the guys were actually SSgts and TSgts) at the chow hall because I'm wearing a green fleece with a flight suit (I'm sorry, seeing as how there's 10 feet of snow on the ground and this is the only "jacket" I have, I thought common sense would prevail) and the grand-daddy of them all... "Doing more with less".
All of that crap and more, coupled with the thought that you could spend 15 years dealing with all of this sh*t and then end up getting non-continued or RIF'd or the scarier thought that's now the issue... you could 15+ years in and then end up losing our current retirement plan and end up years behind your peers in the civilian sector.
I'm raging just typing this up...
