As a disclaimer, my boss scheduled a weekly 30min 1:1 when I started, but with the caveat that we could make it less often if I found it not useful. He just preferred weekly during the "settling in" phase.
Almost without fail, our 1:1s go over time, totaling between 45min and 1hr. I can't imagine how my boss finds the time, but I so appreciate that he does.
I keep a pinned slack message in our DM, of priority-ordered things to discuss. Often these are things like:
- Something went wrong this week. How did I do? How could I have performed better?
- I noticed something unhealthy with our team, how can we fix it?
- You did something that surprised me as a manager, what was your thought process (this is sometimes critical feedback, sometimes curiousity)
- Is this thing I want to do a good idea?
- Debrief on progress (or lack thereof) on a predefined goal.
- Help me with this stupid HR/Expense report thing
And the list always ends with:
- leave space for <BOSS> to discuss things he wants
This is easily the most valuable growth time of my week. I appreciate my IC time to do an excellent job, but the 1:1s help me pick my head up and think about bigger things.
I always preferred managers like this, who are not totally dogmatic about things like weekly meetings - instead doing what works best for each individual.
I'm with the OP that 1:1 every 2 weeks is better.
As other commenters have said, the 1:1 time is the report's time. It's a chunk of time in which I'm entirely and exclusively available to them. I have a set of standard questions I can default to, mostly trying to understand how they're feeling, and open-ended enough that they can talk about whatever they want. Some are done in 5 minutes with a progress report, some take close to an hour in which they sometimes share personal stuff; it's all good from my POV, happy employees are productive employees.
It's absolutely not just about their job/career path. You wouldn't believe what a MASSIVE difference it makes for people just to be heard and have your undivided attention.
