A one-on-one is the report's meeting, not the manager's status update. If you find yourself asking for progress on tasks, move that to a written update and give the time back.
A simple agenda
- What is on your mind this week?
- What is getting in your way?
- What would you like more or less of from me?
- Anything we agreed last time that we should revisit?
Write commitments in a shared document so both of you can see what was promised.
