Man, I got ya'll beat. My dh does a "standard" 7-5 M-F type thing, with occasional weekends right now, but is ALWAYS on call. Has to carry a cell 24/7, and can't go more than 75 miles away from his job without permission. He worked Thanksgiving and Christmas last year, and when I had my ectopic surgery - yeah, he was called in an hour after I had left the OR.
But, later this year, his "standard" job will go haywire, and he'll basically be at work for 6 months, unable to come home. He'll eat, sleep, dress, WORK for 6 months.
Can I complain? No. Because there are others who get to do the same for 12+ months at a time. But I will increase his life insurance policy, and pay the exorbitant cost of all that, because theres a chance he won't come home, and dammit, if he doesn't, I want to be able to pay off all the stuff we have, live for umm... forever off the interest money, and blow a bunch of money in retail therapy.
So, be happy with your long hours! Because atleast he's "guaranteed" to come home at the end of the day, and you don't have to see pics of the tent that he was sleeping it 20 minutes prior blasted to smithereens by some a$$hole (ok, that was my brother, not my dh, but the idea is still the same! And no one was injured in the blasting, but if he had been sleeping there, he wouldn't be here today.)
End rant.
