What's ironic, if you complain to the DON, she will whip out a staffing matrix and prove to you that you were fully staffed (and safely staffed, so suck it up and deal!)
Sounds like the House sup and everyone else is afraid of losing their jobs. I can't tell you what to do. I can relate to the buy out and sudden changes. I had a wonderful job, it was really busy but then there'd be a little decrease in census so we'd have time to catch our breath and regroup, when it was bought out and combined with another hospital, there was only busy...and then to the point of stretched thin, then thinner, then dangerous...but according to the staffing matrix, everything was just peachy!
