I have seen basic workers that have better leadership skills than managers. And yes, leadership requires skills, mostly social skills.
Which is why ranks are fundamentally flawed, because someone who has no idea how to do something but still has higher rank can tell the person who is leagues more experienced than them how to do their job. Which is the most infuriating thing in existence.
Sure, some structure is necessary, but overall the "managers" should leave the actual experts alone and let them do their job.
