I hate those posters.
I have one at work that says "Leadership is empowering people to shine like beacons in the night" or some such new-age, Kumbaya singing claptrap.
I've been sorely tempted to put a post-it note on it that says "Leadership is getting someone down do some shitty job that no one else will do - and thank you for it"
Unfortunately, they would know it was me.....
