Packard's 8 Hidden Human Needs makes an interesting read. 

Reassurance of Worth (is it the same as need for recognition??) and Ego Gratification (this seems to be hinting at some kind of 'Lord of The Flies' scenario) especially caught my eye.

One could argue that since the title itself is emphasizes on the work 'Hidden' there could perhaps be more than 8 of such needs. Some still hidden under the complex nature of man.

How about the 'need to protect self or need for self-defense'? This could potentially stem from the 'fear of unknown', thus exposing the line managers to exploitation by the ones who claim to have the know-how. How would you as an HR manager stop this exploitation? Or are you the HR leading this exploitation?

How can the top management distinguish between people promoting the corporate agenda and self promotion?

Hence the importance of checks and measures at every stage.

Hidden Human Needs... an interesting concept that once again puts human psychology at the heart of HR.
