Don't just sit there and ignore or avoid the issue. Encourage candor at all times. You may be surprised how much you will learn by simply asking a few questions. Good leaders, by their actions and presence, attract good people and fill their ranks. Counsel, encourage, reward, mentor, discipline and develop subordinates.
Respect is a two way street.
You will only receive the same degree of respect that you extend to others. Prejudice and sexual harassment have no place in any unit and will not be tolerated by anyone, anytime. There are no second chances in these areas. Leaders delegate authority but they must always remain responsible for all actions taken by their unit. NCOs must be held responsible for soldiers assigned to them.
