Need some peer direction

OK. So, I have been a LPN for over 6yrs now, all in LTC/Rehab except for a temporary stint in corrections when moving to Atlanta. I unfortunately have had a new job every year since moving here; some I have left voluntarily, some involuntarily. I have left the majority of my Charge Nurse positions because I refuse to be mistreated and disrespected by my superiors who feellike they can just because of their position. I simply do not tolerate it. I let them know that if they feelcomfortable doing it to me, I will return the favor. Unfortunately for me though, I have been labeled as come having a "bad attitude, unprofessional" and once as "insubordinate." AT NO TIME has my work or my performance been labeled as poor; nor has my judgment come into question. I'm outgoing, hardworking, dependable (never calling off, picking up extra shifts for the facility not cause I really wanted to, not being late), and ambitious. What I don't understand is why when my one year anniversary comes or is coming, why all hell breaks loose for me and I end up just leaving or I get terminated. I genuinely want to stay on a job for an extended amount of time and I want to "move up" but, its something that's elusive for. Out if frustration, I've decided to start my long overdue journey to study for my RN. I must say that I am from Ohio; and since living in GA, I've noticed a "difference" in the mindset of people here. I know its not me because, others that I have met from places other than the south notice it too. With that said, someone please offer me some kind of direction. I'm really frustrated.
