I’ve largely made a career out of teaching and consulting on the points raised by this post (and related ones), sans the political angles. Even argued with people on here about such things — ex-military types who believe leadership is a one way street: the boss talks, you do what he says. There’s nothing new here; these so-called techniques (bossing around) never worked, at least not for long periods of time. The problem is that the response is often going all the way over to the other side — trying to be friends.
A great leader gets his people to do things because they want to. As a Marine NCO and SNCO I rarely had to resort to the old “because I said so” way of doing things. Train your people to the point that you can disappear on leave for two weeks and things still run as if you had been there. Train your people to take your place, give them ownership and hold them accountable. Allow them to come up with ways to do it better and let them implement them. Allow them to fail as long as they are doing the right thing, then constructively critique their effort and allow them to fix the problem. Do this, and they will crawl through Hell in gun powder suits for you. I left the Marine Corps knowing the Marines that were put in my charge were going to be good leaders.
