There are several leadership styles that can be adopted in different situations: autocratic, bureaucratic, democratic, and laissez-faire. The autocratic style involves a leader retaining power and authority without staff input, while bureaucratic leadership manages through procedures and rules. Democratic leadership encourages staff participation in decision-making. Laissez-faire provides little direction from the leader and gives staff freedom. The most effective style depends on factors like the manager's background, the staff being managed, and the organization.
