I'm very pro remote working, but I think people like me need to realize that this is a real issue. It happens in the office too, but it's a bit harder to get away with, and it's really a performance management issue which brings us nicely to your second point.

I agree, managers are always the worst offenders when it comes to this sort of thing. But they do the same in the office by disappearing into meeting rooms for the entire day. I'd love to know how you can effectively manage a team by constantly being in meetings with other managers.
