Well Cindy it depends... usally after 6 months probation...we usally stop calling him or her rookie...if it stops acting like one...and sometimes up to a year if he is low man on shift. As for your Cap question .. it would be dissrepectful to call a captain by his first name or nickname in public or on shift,around the station or on runs its always CAP or Captain.... Never Toad or Brian....sometimes it does slip... but thats ok.
