There’s a place for the term, “manager”, but I don’t like what it’s come to mean. “To manage” has come to mean being responsible for processes, schedules, inventory, projects and people. One can manage most anything, but we should not be managing people.
I don’t want to be “managed”. I’m not a thing to be directed, changed and ordered about like some factory robot. I am a human and, as such, I need – and deserve – more than being handled in the same manner as an object or an idea.
