Ned, I was in a similar situation several years ago when I was offered a job in a different division within the same corporation. LOML gave me good advise, “Loyalties are important but you have to do what’s best for you”. I took the job even though I hadn’t been in the current position all that long. I felt bad about it for awhile but it was the best move of my working career.
Good luck to you.
