I normally keep my desk clean and non-cluttered, but depending on the flow of work this is not always possible. And cutting out 3-5 minutes early is not an option, just to clean the desk and put things away... I'm often here late, trying to meet suspenses and then needing to rush out to pick up the kids from daycare before they close. (And most of the time, these late nights are on me, no comp time, no overtime..but that's another issue.) And these will come on for a week or 2 at a time. When I do get down-time, I'll get my desk cleaned back up, files filed appropriately, notes and other bits of paper transferred or destroyed, as appropriate, normally just in time for the next 'emergency' to hit and require all of my time and attention. Since I'm not in a traditional "Admin" role, my duties and suspenses are a bit different, so habits that I aquired as an admin aren't helping a lot on the day-to-day issues, but overall have helped me become known to my co-workers and supervisor as meticulously organized. Just means my boss thinks she should give me more work to do, so not always the best thing.
