Here's a question you can ask your team members in your upcoming one-on-ones. 

Give plenty of time and your full attention for this one.

Do you feel listened to and heard? Why or why not?

Listened to = When they speak they are not talked over or abruptly dismissed. They feel like people want to know what they have to say.

Heard = People respond to what they say and capture the essence of their ideas, feedback, or feelings.
