I’m fairly certain this question applies to American and Commonwealth armies. Not sure about others.
It is frequently said that a newborn second lieutenant should listen to his sergeant’s advice, and follow it. The 2LT outranks the SGT, but the SGT has far more practical experience.
Are there any circumstances where a 2LT reasonably should overrule his sergeant? If there aren’t, then why doesn’t the rank structure reflect that?
Doctors and nurses, outside hire managers and the seniority worker they manage.
The most experienced person under you is the greatest asset in navigating the expectations placed upon you that only your team can make happen.
Ask for their advice, trust their council, make the hard decisions that get the job done and understand you will seldom win both camps.
