There are times
Every situation should be analysed on its own merits, the whole point of sitautional leadership is to use the right style at the right time.
Is there a right time for autocratic leadership - of course there is. One would hope though that the manager takes steps to ensure that autocratic leadership isn't required continuously, through mentoring/coaching/training. If a manager is stuck in the same style all the time, they are lazy, stupid or both.
