Agreed. It's just so clear to me that role(s) flex between those set of tasks as need be ... and that should be clear to both manager and managed ...
The manager shouldn't be a control freak about being in the office 5 days a week ... and the managed shouldn't be a whiny baby when asked to come do some human stuff ... somewhere in the middle is the promised land and it should't be that hard to find.
Having said that ... I had an experience with a colleague recently that reminded that not much of this is based on reason.
