Leadership - How Do You Balance Authority With Approachability?

As a leader, how do you balance authority with approachability? I want to foster a trusting kind work environment, but still be strong and decisive. So i would never say that being approachable diminishes your authority. Being approachable doesn't mean anybody can walk in our office any time of the day and take up an hour. That's not the same thing. What we want to we want to be we want to bring the human side of leadership. And that's going to create trust in chemistry, help smooth the organization forward.
