Also, not to intrude on mid (hey, girl, BTW! She works in one of the ICUs in my hospital!), but not every unit is that way.
The unit I'm on is completely different. I'm on the Bone Marrow Transplant unit at Wilford Hall Medical Center at Lackland AFB, TX. I put in very little off time for meetings, and when we do, we're "compensated" with an appropriate schedule for that week. We, too, work three shifts one week and four the next, but in my case, I seem to get more time off now than I did as a civilian RN.
My unit does not do on-call.
I, too, have earned 36 CEUs this year (I got here last November), and am about to earn four more for another class I'm taking next week.
Each unit is different, but one fundamental thing is the same - once you're in, you're in; the military is an all-encompassing way of life, and not just for you, but for any family that accompanies you. In many ways you're at the whim of the Feds - they can move or not move you, deploy or not deploy you at their own choosing.
But I wouldn't choose to be anywhere else.
