I have this person in my team who always seems to do exactly what he wants to do - he does stuff that he finds interesting, during the day, rather than what he is supposed to do. The stuff he is supposed to do does get done, but he is working/emailing until the small hours.
We have tried being more directive (I say "we" - I do not directly line manage him, but I head up the team) and getting him to tell us what he has on during the day, but he just tells us what he wants to hear and then does his own thing - eg he will go and listen to a talk on farming, then do his work after hours.
I am getting more and more pissed off with his behaviour - he rarely copies me or his line manager into work that he does, but just goes straight to the head of the office (I am no. 2). Either he doesn't like being managed and just wants to do his own thing, or he thinks he should be managed by someone more important. Head of office has brought his behaviour up with me, saying that I am "failing to lead" this person, conveniently ignoring the fact that the rest of the team work really well. I have spelled out what actions I and his line manager have taken, to show that this is something we have been trying to grip for ages. I have turned the tables and asked head of office what he would advise next - he unhelpfully had no suggestions, beyond saying it needed to be sorted out.
I've been leading teams for over 20 years, and have never come across this sort of behaviour before - does anyone have any suggestions about what we can do next?
