You know what drives me crazy? Fake due dates. If something is due on Oct. 1 please don't start sending "late notices" til October 2. I do not care if I am the only one who has not returned something or done something. I will do so by October 1. I do not go through paperwork or emails every single day. I flip though to see if something needs immediate attention, if not, I complete things on Thursdays. Otherwise I would sit at my desk all day long. So if you need something on September 25, put "Due Sept 25" on it. Not Oct 1.
Stepping off my soapbox. For now.
