|Hmm, where to start? Well, I met my wife 12 years ago on a gig in the big city. One of our first conversations was about my job, and the fact that the next step up the ladder probably wouldn't see me in the same city. She nodded and said "OK!" So, 7 years of marriage, two children, and 2 jobs later, I've got what I consider to be the '747' of bush jobs: it's stable, adequately paid, has benefits and a pension plan, and doesn't appear to be in any danger of going bankrupt. On the other hand, I give up, pretty much, my entire summer to it. I leave on April 1st (sometimes, depending on the season, get a small break at the end of April) and return home by about the middle of September. I do get 12 days of holiday in the middle, depending on schedule, though.
My wife is completely onside, realising that my job, as hard as it is on us as a couple and personally, is good for us as a family - it pays for the house, food, cars, vacations, schooling etc. Do I feel guilty about being away a great deal - yes!! and as my children get older, and sports days, science fairs, etc... loom on the schooling horizon, it gets worse; Skype helps a lot, however. And, if I do the math, I spend more time with my children than my brother, who is a 9-to-5 office monkey( ), does with his.
I/We could make the decision to live in the same town that I work in, but have, for a variety of reasons, chosen not to. I/we could also make the decision to search for another job that might see me at home more regularly, but again, for a variety of reasons (see '747' above) have chosen not to.
I could go on endlessly. PM for more if you wish.
