I've worked for a company for 15 years, my role has evolved over the years and I've progressed etc. I'm not a manager but I'm senior with direct reportees.
A reportee I recruited 5 years ago has progressed and last year before I went on mat leave his job role changed and he no longer reported to me. I was pleased for him as he is bright, a hard worker and it was well deserved.
The company is continuing to grow and there are a series of departmental changes happening, lots of new roles being initiated and lines of reporting changes. I recognise the need for this and support it. The changes don't affect what I do however it will change who I report to. A new role is being created who I will report to. They are only accepting internal applicants to begin with, I'm not applying as parts of the role don't suit me but the person I recruited a few years ago is applying and has an interview arranged. I support his interest but this will make him my line manager but I'm afraid this makes me uncomfortable and doesn't sit right with me. I don't know whether to raise my concerns, hand my notice in or just run with it. Any advice on what to do in this situation would be appreciated.
