There is a tendency for autocratic leaders to lack the skills needed to lead a team, so that teams end up directionless and confused. Other autocratic managers supply such rigid constraints for teams, that there is no point having a team at all. . Autocratic leaders tend to use elastic authority. This elastic banding confuses teams since they can never tell what the bounds of their authority are, or, they realize it's all a sham, and they have no autonomy or power anyway, just the appearance of it. . When we have an autocratic executive in an organization, this makes effective teamwork at lower levels difficult, even though that work unit may have a more participatory leader.
Some tasks require teamwork, while some tasks are best done by a single individual working alone.
Some require a mix. If you have a predominance of job tasks that are best done independently, then productivity can suffer if you try to shoehorn them into a team situation. Writing is an example of a task that is best carried out by a single individual. Having more than one person working simultaneously on the same piece of work is likely to stop effective writing in its tracks, because teamwork disrupts a process that occurs primarily in a single brain. Putting together an entire magazine, however, is an example of a mixed task.
