I had to do it with Michael Parkinson at LBC. He never cleared his stuff off the desk so eventually I 'filed' it in the bin. Language? You've never heard the like.
We had a situation in our office some years ago that a parttime guy was supposed to hotdesk with a fulltime employee, what happened was we stole a desk from another department and he sat in the middle of an laready tiny office surrounded by three other desks including mine and the boss's.
