DROP isn't worth it if you have firm employment opportunities after retirement. Whatever your lump sum payout will be, it will be more than made by a decent paying opportunity. That is of course, if you're planning on working after retirement. The only ones in my agency who've shown interest are the high ranking pencil pushers, as far as I know, no one on the road is interested. That lump sum won't do much for me stretched out over my remaining life and I'll be that much older trying to enter the civilian workforce. No thank you.
