My now ex-manager was unexpectedly fired this week and he was not given an opportunity to address anyone or even send out a farewell email.
I'd like to reach out via LinkedIn to express my gratitude for all he has done for me as a mentor and manager (I would not have this job without him, actually my position wouldn't have even existed without him), wish him the best on his next venture as he deserves to work for a better company anyhow, and solidify him as a reference for future opportunities.
How long is it appropriate to wait before sending him a message on LinkedIn?
It is my understanding he did not leave on the best of terms so I feel waiting a bit is appropriate but not sure how long, or maybe not waiting is best as it might lift his spirits to receive a thoughtful message after a rough week.
