I have a mid-level manager that reports to me and told his directs that he's resigning. He hasn't told me he's planning on resigning and hasn't resigned. He's actually on track to being let go, we've had several meetings about it and are putting a PIP in place this week. We'll be happy to see him resign.
What is the appropriate reaction specifically to him telling his directs he's planning on resigning? Can we ask him to resign immediately since he already told his directs he's planning on resigning?
In general do people agree it was inappropriate for him to tell his directs he's resigning before telling his supervisor or HR?
