When an E-4 calls me "hey" or "hey man" knowing that I am an officer, should I bother to correct him?

As a veteran officer, I can tell you the days that drove into soldiers attention to detail. That includes following regulations and set guidelines. I know that today's world is different, but rules and regulations are to be followed. Remember you set the example, if you allow this to continue, it will become the norm. These men and women will follow you into combat one day, set the standard and expectations now before that day comes.

Perception is everything. Folks will believe that you guys are homies (which you're not) and that he has the hoook up with you (which he doesnt). My advice is give him point of correction. You don't have to rip his ass, but he does need to know who he's addressing whether on or off duty. Just my thoughts......

If you want to maintain your respect & position, correct the E-4

You need to "check fire" on the SPC, simple as that. Squash it now before it becomes a new standard.

Yes you should. That is disrespectful

Well yes! Absolutely

Only if you are both in uniform.

Yes. Read SFC O'Mally.

Out side of work isnt really a big deal in my opinion. You are a person just like he is. I work with officers and warrants on a daily. At work and in uniform its very respectful. There is a time and place for everything. Humanize yourself to him and he will respect you more. The biggest issue i see in the army is the Separation of officers and enlisted. Once you realize the people that work for you(enlisted) will take care of you if you take care of them, there will never be a problem with respect and trust. You stick your neck out for him he will do everything in his power to keep you from getting yelled at. He isn't a robot and neither are you Sir! Who knows one day he might be your platoon SGT or even 1SG.

Are you an idiot? If you don't know the answer to this question, you do not deserve the metal on your shoulders. It is your duty and responsibility to correct this person. If not, YOU are derelict in your duties.
