Wrong person responding here. I generally have good relationships with my admins, but not because I work hard to get along with them. I have the reputation in my district for being blunt, in your face, and out-spoken. So that my current admin has been known to say at staff meetings: "So, Kelley, tell us how you really feel."
Still, we have a good working relationship; because, despite my recalcitrance when it comes to top-down directives, they know that they can count on me to give my best to the kids. To put the kids first. And that when I am voicing dissent, it is always in defense of our primary mission: learning.
