I recently accepted an offer as a manager at a medium sized company. I do not start for some time and I have not given notice to my current employer yet.
This role was to report to PersonA who is a department manager. The bareboned intent of this manager role as I understood it from the job description and interviews was to assist PersonA by managing a few of the teams that report to them. As a dept manager they had all of the teams reporting to them and were looking to offload some of that to my role. This position as described was appealing to me and I accepted the offer.
Some time goes by after my acceptance and PersonB also with a title of department manager who is a peer to PersonA (in the same department) reached out to me. PersonB told me that I will be reporting to them instead of PersonA and I will be playing multiple roles (including manager) on 1 team instead of managing multiple teams.
This feels like a significant change from the role I had accepted not only in scope but who I am reporting into.
Are my concerns enough that I should reconsider the acceptance or am I overthinking these changes and their significance?
