When a followers has frequent conflicts with her boss and the leadership style?

Autocratic or Authoritarian leadership style.

An authoritarian leadership style is illustrated when a manager commands strategies and procedures. He himself decides what goals are needed to be achieved and controls all activities without any significant cooperation from the subordinates.

Such manager possesses full control of the team, leaving low freedom within the group. The group is demanded to complete the tasks under very close administration, while unlimited authorization is self-bestowed by the leader. Such situations result in the frequent quarrels between the manager and followers.
