A consultant was told by a manager in a paint factory about his boss - "I do not trust him, nor does he anyone else. He says one thing to your face and another behind your back. He doesn't actually lie, but he deals in half truths". Here was a men dedicated totally to self advancement. This boss, when confronted by the consultant, dismissed leadership as 'kidology' and added "why should I tell the truth to my people on the way up, when I do not intend to come down again."
This is an example from an enterprise in the UK, but the whole world is getting a large number of such self centred 'climbers'. In the long run, they are doing a great deal of damage to their enterprises because of their lack of character.
