Topic: The Club House / Does work sometimes conflict with home life?

I have been grieved by an Inmate 2x within a month for sleeping on duty. The Inmate has lied on me because of his infractions. He was given a verbal warning for the 1st infraction and found not guilty by classification on the second. The classification staff interviewed other Inmates at not an officer who witnessed the incident. Inmate are manipulating the system and aren’t held accountable.

How can I file a complaint on Inmate for lying on me? I haven been to Internal affairs once before for this inmate, I was found not guilty of sleeping on post, so the same Inmate has decided to make the same claim again against me because he was not happy with me writing him up. He had 3 other inmate lie for him.What are somethings that I could do to protect myself.?
