I recently accepted a new job offer with another department within the same organisation. I told my manager who was supportive and we kicked off the transfer process.
A senior manager several levels up my management chain called me and basically threatened to hurt my career if I continued with the transfer. She said my reasons for moving weren't good enough and she is friends with other senior managers in the new department.
I'm not overly important to my current team, but this senior manager is haemorrhaging people from her department and struggling to hire so it's starting to raise questions about the morale of this team.
I'm now in a very awkward situation and don't know what to do. She said this over the phone so I don't have any evidence she threatened me.
I am moving forward with the transfer but how should I protect myself or prepare for this person to do some damage?
