The top rule for bosses should be to respect and trust your employees.

Respect should be easy. Pay them and treat them how you would like to be paid and treated. Listen to their ideas and discuss them rationally.

Trust is also easy. You hired them to do a job, so trust them to do it. No mandatory goal or training quotas; they'll tell you what they need or want to do. Allow them the privacy they need to do their work.

Bosses should just be there to enable the work, not dictate it.
