charge

I worked as a "working charge" for over a year and a half. Usually taking one less patient then my coworkers. I am a tier, which is a prn position. I filled the position of a full time charge that left. She had taken a travel assignment and after 1 1/2 years decided to come back. I was 2 weeks late getting my acls renewed, when they told me I would have to removed from the charge position because I could not be charge without the acls. As charge, even though I also took a full pt load, I still helped my coworkers, helping with admits, orders, etc, plus all duties of a charge. My concern is the charge that returned, wont help, she will do the assignment for the oncoming shift, and the code carts. Even the other nurses I work with complain that she does not help. She can be sitting five feet from me, and the other nurses still come to me for advice. I have tried telling them to go to her, but they wont. There was one instance when the tele tech told her that room such and such was in v-tach. ( our tele station for the hospital is in our nurses station) she called down the hall, and told me your pt in room *** is in v-tach. I asked her in v-tach or a run of v-tach? she said I don't know and walked down the hall the other way. Fortunately the pt was not in sustained v-tach, it was however a long run, something like 19-20 beats. My point is even as a co-worker, I feel it you thought a pt might be in sustained v-tach you could at least help, let alone being the charge. I have voiced my concern to the directors,they listen, however nothing changes. I have been told as a charge I did a good job, but now they want the charge to be full time. My coworkers complain to me, that they want me back as charge. I don't know what to do, I can not afford to take a full time position. It has been 6 months since I left being charge, and the other night, after I asked the charge nurse how her Pals class went she said good, I take my acls class in 2 weeks, turns out she let her acls expire when she went traveling. This was the initial reason I could not do charge anymore? I don't know what I should do, I live at least an hour and 15 minutes from any other hospital. Any advise, help!
