Passiveness
Leaders cannot be passive. Direction must be given. The needs, wants, thoughts of the leader must be known and asserted. Leaders need not be aggressive. They must, however, have the full range of assertive skills, ranging from basic assertion of their needs through to consequence assertion when their needs are not being met.
Unaccountability
Leaders take accountability for their actions and the actions of those they lead. People who influence groups to take group decisions and hide behind the group decision are politicians, not leaders. So are leaders who delegate responsibility for making a decision and do not take accountability for the ability of the person so delegated to make the decision. Leaders acknowledge their mistakes freely, safe in the knowledge of what they have learnt.
