Leadership Definition - Autocratic
Wikipedia defines Autocratic leadership style as:
Under the autocratic leadership style, all decision-making powers are centralized in the leader, as with dictators.
Autocratic leaders do not ask or entertain any suggestions or initiatives from subordinates. The autocratic management has been successful as it provides strong motivation to the manager. It permits quick decision-making, as only one person decides for the whole group and keeps each decision to him/herself until he/she feels it needs to be shared with the rest of the group.
