I've been on staff with a nursing agency for the past two years. Until this summer, I was just doing per diem clinic work for them, since I was going to school full-time. Last month, they offered me a part-time 5-week home care position, which I accepted. It was due to begin next week. Two weeks ago, they called me to ask if I'd cover another client for 3 days this week. I accepted. It went fine, though it was a draining assignment. Yesterday afternoon, after I finished my third and final shift with the client, the agency called and asked me if I wanted to work with this client full-time for the next 6 weeks, because they don't have anyone lined up for the client. I was very surprised at this, since the client's mother (it's a pediatric patient) told me that new nurses would be starting next week; she had been told that there was coverage. I reminded the agency person that I had already committed to another assignment with them, and she said it didn't matter, because that client was easier to cover, and someone else could do it. I told her I'd be willing to cover the client part-time, but couldn't do five days a week (honestly, it's because this assignment takes a lot of energy).Well, today the agency called me back and said if I want to cover 2-3 days per week, that's fine, but then they'll reassign my original case to someone else, because they don't want to split that one between two nurses.I'm frustrated with this whole situation. It's not fair to the client's mother, that she was told there was coverage when there wasn't. And why should I have an assignment taken away from me because they couldn't fulfill a commitment? I'm also mad at the agency because they made a mistake with my last paycheck. Plus, for both cases, they gave me inaccurate info about the client's; I didn't know the actual ages, genders until I met them. Is this stuff pretty common to staffing agencies, or is this one more disorganized than most?
