I've just started a few weeks ago in my current role, which was a lateral move. I've been at this level (think NHS pay banding) for about 10 years and am quite senior. A job has just come up in my area that is a promotion to the next level. It would involve more leadership, a pay rise (nothing extreme but I'm currently at the top of my salary scale so another 10k worth of increments), a better commute and this type of role doesn't come up that often. The better commute would also mean I would get home earlier for my teen DC after school.
If I apply and am successful, it would mean leaving a few months into my current job, I wouldn't even make it to a year. I wouldn't consider this for another lateral move and if just unhappy would always stick it out for at least a year. I know that the manager in my new job would be very upset to lose me as she has lost a few staff in recent years and I came in with a lot of experience.
I would be interested in any perspectives on whether AIBU and to what extent, to leave for a promotion this soon?
