When do you go to a first-name basis with people?
CSM Blount,
In my career field (fire protection) we tend to have a first name basis unless we are in a public environment. While at the station we will call each other by first name, last name, or nicknames (mine being Hurricane) since we spend more time with these guys than with our own family. I personally don't call anyone by their first name, I always call them what they are (Airman, Sergeant, Chief) and their last name, even the civilians I call by their last name. I know a few NCOs that call me by my first name but since I am just an E-3 I respect the NCOs and SNCOs they earned their rank. We don't have much interaction with officers so when there is an interaction with officers so when we do it is always Rank and last name.
I've been in units where I've felt comfortable calling my subordinates by their first names, others where I haven't. It depends on the culture, the esprit, what's going on in the unit. A place where the unit has its stuff pretty wired, you can be a bit more relaxed. A place that's trying to pull itself together and fix itself, not so much.
