@JoMaloneCandles and I seem to think similarly.
Work hard yourself, and if they ask you a question or to approve or reject something, do it promptly.
Be fair and approachable - no favourites.
Be flexible, as long as the work is done, understand that people have lives outside of work.
Care and ask how they are.
Support their career progression.
Definitely don't be a micromanager, this is a huge source of attrition in many companies.
Praise in public, difficult conversations in private.
Be transparent, communicate targets and company updates.
Encourage them all to see the bigger picture and how important their work is to the success of the company.
