I loved this sentence:
"However, I do believe that if the title and role was mentor, even someone with autocratic tendencies might start to adopt a different set of behaviors–perhaps with some coaching. Just by the change in title, it sets up a whole other set of expectations with associated behaviors."

I'd love a chance to find out.

I have had significantly more "bossy" bosses than mentors. Brand new first-time managers especially seem to feel that they have to prove themselves by being controlling, bossy, autocratic, and dictatorial.

In my world (programming) I've thought for years that the "boss" should be replaced with more tech leads and project managers. Let the team be a manage the work of its members (I worked in a team like that for a few months. It really can work.)
