What are your thoughts on managers and territory’s and how thin this line can truly be?

Seeing as how most of us are sales people and managers. I think this is a great topic to discuss! I have been put in situations multiple times throughout my sales tenure where I have a “fixed” territory only to find out my own manager gave away leads in my “territory” and later said reps are not to be given credit outside their territory unless it’s an “open” territory. I find these lines get blurred easily, though I always try to take the high road and let me colleague take the win. I chalk it off to disorganization, seeing as how everyone has so much shit going on they don’t really know what belongs to who.
