DDD, is this a State prison? Yes, there are a lot of "off the wall" employees but actually they are extremely strict with what the employees are and are not allowed to do. They may ACT off the wall but in truth, you have to be extremely responsible and very tolerant and not let things get to you. There are a ton of rules and policies, all for very good reason, and you have to follow them or you won't be working there very long. The rules insure that nobody gets hurt and that nobody escapes.
In NO WAY is that job a piece of cake! Not everybody can do it. They learn that their lives depend on having each others backs. You have to be the type that can let a lot roll off your back and you have to learn not to let the inmates get to you because they will certainly try! Some of them are really obnoxious and know exactly what buttons to push. And they make a point to target and test out new employees and try to get them to bend the rules and do things they're not supposed to do. If they stick to the rules, if they're fair and treat everyone the same, the inmates will respect them and they usually do fine. They just have to remember that when it comes to inmates, it is strictly "us" and "them" and there are a lot of lines that you just cannot cross. You have to remember where the term "con man" comes from.
I worked around inmates for 24 years in a close security State prison with some of the worst of them, and I've known literally thousands of correctional officers. Of course, each employee brings their own personalities to the job but some of our best officers have been some of the "characters", the low key "good ol boy" types who know how to talk to inmates and know what to expect from them, but won't let them get away with anything either. It is NOT an easy job. It can be very stressful and it takes a lot of hard work and a lot of professionalism. If it's in a State facility, the pay usually isn't the greatest but the benefits are good and usually those jobs have civil service protection and lots of opportunities for advancement. Our newly hired people had to go to the training academy for six weeks of pre-service training, then another month of OJT before they actually work on their own. I wish him luck and I hope he gets the job!
