Recently one of my old managers told me he is leaving the company. He taught me a lot of things during my time here and I really wanted to give him a recommendation on his Linkedin (even if it might not do much).
I was wondering if there was any etiquette of what employee would write for a recommendation for his/her manager? Is it weird to do that? What would be some things I could highlight that would make it a good recommendation? Should I talk to him first about it?
