ReHeat, the Chairman has the final say in who the Directors are, and perhaps more importantly, who the CEO is, and they will hire people who "mirror' their own values and behaviours.
No he doesn't. The shareholders have the final say who the Directors are if they overstep the mark as they can vote not to re-elect them at the AGM when their terms come to an end. However the Directors do have the final say as to who the Chairman is and can immediately sack the Chairman if he is not performing at any time. Of course the Chairman gets the say about new replacement directors (following resignations etc) between AGMs providing he has the support of the Board.
