#1- calling out anything co-worker related. I try to always bring up some good things. Ie: this new guy is getting up to speed really fast and I'm super impressed, here's some quick examples. Or negative: the guy in the remote team and I keep having conflicts, not sure what to do about it, any thoughts?
#2- my career. I'm working towards promotion X, I've made these steps lately, what do you see that I can be doing?
#3- ask for feedback. Has anyone given you any feedback that I need to hear? I can't grow without it.
And then give half the 1:1 time to the manager for things they've brought. Their time is often even more limited than mine.
