I am an LVN working in the same place where I had been a CNA for 6 years. I will be honest, the transition was hard for me. At first quite a few of the CNA's would not listen to anything I asked them to do, and had no respect for me as a nurse. I did have to put my foot down. The words that changed it all around: "I am sorry that you have a problem with me being your supervisor. If you recall, I did go to school to become a nurse. I earned this position, it didn't just fall out of the sky. Nothing is stopping you either. You're just as capable as I am of becoming a nurse, and think about how you would feel in my position. Go ahead and try to make my life hell, remember I can make it 10 times worse."
The transition lasted about 6 months. I am now nearing 2 years as an LVN, and it is going a lot better. They show me respect, and in turn, I show them respect. There are even some CNA's I have remained close friends with, but that does not change anything at work. I am still their supervisor.
I would grab the job that was offered to you. Yes, the transition was hard, but its an obsticle that can be overcome. There are perks or working in the same place. You already know who's who, you already know the ins and outs of the unit, and you know exactly who to go to when your not having the best day.
Congratulations on surviving nursing school!!!
