The Sydney Morning Herald's "Radar" has a piece entitled, "Who's next to you," giving graphic and humorous descriptions of various "office types."
Although it is an Australian newspaper, I am sure many will be universally recognised. For example, "Some people are experts at appearing stressed while actually doing bugger all, complaining loudly that they're 'flat out' and 'when will management realise we're understaffed?"
The usual office types are all there: Iona The Internalised Stress Ball; Oliver The Office Cynic; Sheila The Serial Meeting Convenor and Wotzisname The Work Experience Student.
Incidentally, the SMH has given me approval to carry their headlines on this blog - something I will do when I figure out the technical stuff they gave me!
