Leaders are people.
Leadership is a process, activity, ability, or relationship
So you are wrong when you say my Leadership says/does something. It is your Leaders that say it or do it.
This is what I learned in a a Leadership course I am in this morning.
I figure it is like using the word Literally; the way we use leadership it can mean a group of people or it could be a process, activity, ability, or relationship. So I don't care if someone says My Leadership instead of My Leaders I know what they mean.
