From the management perspective, I want to know about personal development goals, team member interactions (and problems), and generally just "how you are doing" with a focus not on work product/tasks but on human health.

I block off an hour for each, but want a minimum of 30 minutes of conversation and I can't imagine leaving before then.

When I have mine with my manager, I tend to break it down into four categories: personal, team, department, company.
