I guess I would only say take the job if two things were true; 1) the extra money was make-or-break for your ability to pay the bills and care for your family (i.e. you can't quite make ends meet now but the extra money would get you over the edge to stability) and 2) there was a clear OTHER job with better hours that you would be able to move on to within a reasonable period of time (say after a year). I wouldn't sacrifice family for a few extra bucks that you don't really need, but if this was a necessary stepping-stone to something significantly better, it MIGHT - might - be worth the sacrifice for a year or so.
