You'll have a job if you do that- but you might not be able to advance, you can be the odd person out, and out of sight/out of mind. I did what your friend did once upon a time; within a few years (during which I got a lot done), it was obvious that it wasn't going to work out any longer. Of course that's a possibility with any job, but if there's not many other opportunities around where you moved to, it can get tricky.
