Topic: Everything Education / New Officer

I’m new to Corrections in florida – it’s been four days now. So far they know I like lunch time in order and I ask for IDs. There are some characters that make me laugh but I do try to keep a straight face. From what I’ve seen every Sgt runs their dorms different and speak to the inmates differently. Some keep a straight face while other joke and talk to them. I ran into some trouble in establishing authority because they know I’m new. I’m 4’11 in height and petite in size compared to the other officers. Plus my voice is has a soft tone to it. I’m pretty intimated but I try to stay firm and fair. It’s hard enough to not be polite to those who are because as they say never trust an inmate! Can someone give me some advice as to how I should establish an authority despite of my size ?
