I think it will depend mostly on if your children can be kept on their schedule whether you are there or not.
I was in retail for the first 5 years of our daughters life. And I had super strange hours and days..
Sometimes I also gone for a week or 2 at a time for market.. But because our daughter had HER same schedule each week. It seemed to be fine with her. It was just the way our lives were.
So if they will have care giver or caregivers that can help them keep their schedules that is the biggest hurdle.
I have a friend that is a nurse and she has a very odd schedule, but once again her son does fine, because he still goes home at the same time each week day, does his homework, has a play time, dinner, down time and then bed whether she is there or his sitter is there.
On the weekends sometimes she has to work and so he know he goes to his neighbors home on those days and knows their routines and does fine with that..
They have a family calendar that mom updates the moment she has her weekly schedule. He can look at it and see where she will be and where he will be that afternoon or that day.
As long as no one makes it a big deal, children can adapt. this is their life so they seem to accept it. I think it is harder sometimes for parents, than it is for the children.
