Oozing charm and charisma but with no emotional depth; more sizzle than steak. These are the ones who are manipulative and ruthless enough to do whatever it takes and stick the knife into anyone standing in their way. With their finely honed political skills, sharp timing and chameleon-like abilities, they thrive on risk, chaos and upheaval. And they are cold-blooded enough to claim later that they did nothing wrong.

The worst in the workplace are females, as they can usually manipulate the managers, who are still mostly men, very skillfully.
But I am aware that your reference here is 0bama.
