A book landed on my desk called Office 101: An Illustrated Guide. It's a compact picture book of office-isms (like "Don't get carried away on Casual Friday") accompanied by silly illustrative photographs (like an office worker with his mug of coffee, dressed in a carrot suit).
One of author Geoffrey Day-Lewis's office rules plays on Rudyard Kipling's poem "If":
If you can keep your head when all about you are losing theirs, it's quite possible you haven't grasped the situation.
Another: "If at first you don't succeed, destroy all evidence that you tried."
Dear readers, what office-isms can you offer?
