Desks should be clear anyway,...
... we operated a clean desk policy during my time with IBM, and weren't really allowed much to be on show, no lists of phone numbers, no family photos, no personal items (I wouldn't get away with the cacti I have on my current desk.) I got dinged for having a floppy disk on my desk. I can't remember what it had on it now, but I'd lent it to someone, who had returned it, and put it on my desk when I wasn't there. We got audited, I got bollocked.
