Considering the uncertainty of your current job, versus the possible long-term advantages of the other position you've been offered coupled with the fact that there are not too many decently paid jobs on Vancouver Island these days, I'd make the move even if it meant less money at least in the short term. Indeed, I went from a very stressful high level job with a high 6-figure salary to a mid-$20K job with little stress and a lot of fun, and never regretted my move. I went back to my old career recently, but the motivation was not money. Mind you, I am almost 57 and FI so my priorities with respect to career, and my financial needs, are vastly different than those of a younger person.
This being said, my wife and I are planning a move to Gabriola Island within a year or two. My plan is to kick back and relax, do some sailing and gardening, a bit of travel, and not much more. My wife being much younger, wants to stay in the workforce for another 5-8 years, perhaps as a caregiver or helper for older folks, pet-sitting, or something else stress-free. She is not career-minded, and money is not a priority, so even working minimum wage for a local coffee shop would suit her fine. If you have any insights about living and working on Vancouver Island, I would appreciate your thoughts.
