My manager is leaving soon and I've been told that during the interim period until his successor starts (expected to be at least three months) all his other direct reports will be line managed by another senior manager whilst I will report to one of them, so effectively a colleague becomes my manager.
She is a higher grade than me (I am the lowest grade out of the group) but has no knowledge or experience of my field and - she has been quite clear about this - no interest in it.
I was originally told this was for admin purposes only (annual leave approval etc) but she has asked to see my last appraisal paperwork and set up a meeting with me the day after our manager leaves. She has also told me I will have to take on some of her duties if she is standing in for the manager and suggested that we will all have to take a share of the manager's workload during the interim period, very specifically including me in this.
I'm really unhappy about this - is there anything I can do? Either I'm too low a grade to be treated the same way as the others or I'm part of their team to cover the work - they can't have it both ways, surely?
Or is it just the usual story that I just have to put up with it? My concern is that the job could be downgraded/new boss might leave me reporting to colleague.
This is in the public sector and no one will be paid any more during this time.
Thanks for any advice.
