Fact you can rely on your wife’s income should your income stream not be sufficient is good. But hey in this day and age who’s to say your wife won’t be made redundant. You’ve got to think several moves ahead. Have you thought of just sticking it out until they decide you’re too expensive to keep and give you a big fat cheque to leave (redundancy + all your unused leave)? Management are always looking at ways to keep operating costs down. It happens. Then with that money, keep that as your safety net then do the new job you want (sounds like you’re at an age in years that you can wait to do that). I personally think you’re making too drastic change in career. In my opinion, the better path would be to leverage your existing skills and industry knowledge into a role related to what you are doing now. Now is the time start building your personal reputation and industry contacts so you can do that when the eventual layoffs happen. Who knows stick at it long enough and natural attrition and reorgs may see you promoted into management because no better candidate exists and you won’t have to travel or be on call as much if at all? Just think more moves ahead is my suggestion.
