There aren't very many "relational leaders" out there. Here are a few basic actions that to me, describe what a relational leader (rl) looks like:
They care about their staff outside the 9-5 window.
They are the first to admit a fault.
They don't expect others to do what they don't do.
They give frequent recognition, especially in public.
They treat everyone in the same manner.
This is certainly not an exhaustive list but some of the major items. I hope to addore soon.
