There are lots of lousy managers out there, and you can’t control that - but you can set the agenda of your 1-1 yourself if they don’t have one. It’s your 45 minutes with the person who signs your checks, use it to your advantage.
Search the net for questions / topics to manage up in 1-1s.
I often ask my manager for feedback, ask about expectations for promotion, career opportunities, ask advice on problems I have, ask how I can get my thing prioritized, brief her on something I think she should be aware of and what I need from her, etc.
Don’t let your manager turn your 45 minutes into a waste of time.
