I've been with my current employer for almost 10 years, during which time I've been promoted several times, and now am senior in a close-knit team of colleagues, most of whom I would also consider friends, including my immediate line manager. It's a large, well-known employer and in the main they have been really good to me.
However, we are under-staffed and under pressure and much of the time I feel as if I'm going through the motions. I'm a bit burnt-out, I think; the job can be high-pressure and we deal with lots of emotionally draining situations a lot of the time. We are constantly being asked to more with less and I'm just really tired, frustrated and fed up a lot of the time. But it's a good job and a good salary and I could have many more opportunities there if I wanted to take them.
We're moving house and I intended to commute a couple of days a week, which would be a long commute (2 hrs) but manageable.
However, a job has just come up in the same field (but in a much smaller and perhaps less well-respected employer). It's 4 days a week instead of my current 5, less senior, less responsibility (at least at first), much shorter commute (20 - 30 mins), same flexibility and WFH opportunities. Many of the issues that make my current job particularly stressful would be very much reduced in this new role.
I had an 'informal chat' with the new employer today and it was very positive. I feel pretty sure that if I applied I would get the job.
But...I am feeling so guilty about the possibility of leaving my current role. I know no one is indispensable and I don't want to sound like a dick but it would genuinely impact my team, at least in the short/medium term, if I left at this point. I'd promised to see a particular role through to the end which I wouldn't be able to do if I left, and we have a lot of new junior staff who are inexperienced and need support. The thought of telling my line manager I'm leaving is making me feel sick already. I know they'd replace me eventually, obviously, but I would, undoubtedly be leaving them in the lurch for a good few months at least.
I do also worry that leaving a 'world-famous' place and going to somewhere much less 'prestigious' might not be a great idea in the long run.
So AIBU to feel guilty / worried about applying for this job and potentially leaving my current employer and colleagues?
