Every role comes with responsibility.
When I see you aren’t taking care of your responsibilities I have a couple of options.
If I don’t respect your role, I’m free to tackle those responsibilities myself.
Sure it’s extra work for me, but – especially if we don’t value teamwork – I’ll look good in the eyes of my superiors, and maybe get a promotion.
On the other hand, if I respect the role, and we value teamwork, and you involve me, I’ll do anything in my power to help you succeed.
Respect the role.
