Maybe everyone could be hungout to dry for expenses claims, were they analysed. That is why HP has SBC after all - it's the ultimate get out card to play if they really want someone to go.
However, not everyone is taking $30M+ a year out of the business, and if one is, shouldn't one behave impeccably and be beyond reproach?
I know HP very well. I know of one former employee who was summarily fired for expensing lap dancers. He won a subsequent Tribunal hearing, much to embarassment of HP UK. His defence? He named several senior managers also involved in doing exactly the same on previous occasions, citing them as establishing a Best Practice, they he merely followed.
This stuff is rife, but the CEO should be above it all, especially for some scraggy, plastic, botoxed cougar type. At least it wasn't Rent Boys.
