Am I being unreasonable by handing my notice in now?
I have hated my job - I escaped teaching (which I loved, but it destroyed me) and started a job in marketing at an NGO. It was okay at the start, but I then soon found that it didn't interest me in the slightest, and the lack of human contact and constant screen time started to negatively affected me and my mental health.
Fast forward to 7 months in, and my lovely Line Manager left for a better paid role elsewhere. The company didn't replace him, leaving me to do both jobs (with only 7 mths experience in that field and no formal training). The company said that they wouldn't replace him and wanted to hold his job open with the view to giving it to me (in a year when I have more experience), and they got an agency in for a few hours a week. So I have now taken on a massive workload and am basically now doing the manager job anyway (and I am totally lost because there is so much I am being asked to, of which I have no idea how to do, and am being given ZERO help or training from my boss who just says: 'sorry I don't know'). On top of this, I took a £10,000 pay cut when I first took the job and have struggled financially. I also know the manager job that they want to give me in a year, will be a tiny salary increase - hence why my line manager left in the first place.
So, I have just been offered a job in Student Support at a brilliant University. Much more up my street, in Education, a £6,000 pay rise, great career progression, amazing holiday, amazing maternity (for future planning - my current job has almost no maternity pay), options for doing their apprenticeships whilst also being paid (so I can retrain in another career should I want to) and they seem super lovely! So overall, MUCH better for me!
BUT, I feel terrible. Me handing in my notice will come totally out of the blue, and will be leaving everyone in the lurch. The boss will likely be extremely annoyed because they've kept the manager role open for me, and they will have lost the entire team in the space of a few months. It is also a very bad time for the company in many ways, and they are VERYYY stretched for staff (with another manager quitting in another team last month, who they haven't replaced yet either), and I feel like I will be letting my close colleagues down and leaving them all alone.
I think I am looking for a little reassurance if possible.
Thank you so much in advance! 😊
