How do you change what's under your screen name from "New Hire" to "On Reserve" to "Line Holder" to "Gets Weekends Off" etc. etc.?

Mine went from "New Hire" to "On Reserve" without any input from me (and I picked the "Line Holder" for the caption below the picture).

I'm confused (and I'm neither a new hire or a reserve guy). What gives here? Any help would be appreciated....
