I am leaving my company for a more attractive role at a different company. Should I tell my current manager who's moving to a new role in July or wait for his replacement to break the news to?
A little background. I've worked in this HR role for 4 months now after transferring from a different front office where I've worked for 3 years. He's already lost 2 other team members with long tenures in the last 4 months before me and had to replace them (I don't know how long it took him).
As is, I found out this manager is leaving for a different role in a different branch of our company. He expects to finish his transition by early July. I landed a job with a different company and negotiated a later start date (early August) so that I can give the manager time to find a replacement and see ongoing projects 3/4 through to help transition. Should I tell him this? And should I tell him now? How much notice should I give?
