How are you?
How do you feel?
How is your family?
What can I help you with?
What would make your daily routine better?
What do you want to tackle this week?
How would you go about this?
Is there anything on the calendar you want to push back/reschedule/cancel?
One cannot fake empathy. But these questions are a good way to practice and get accustomed to worry more about the well being of your team than the next looming deadline.
We are in this together.
