As a nurse manager, I can say that most of our staff left for two reasons. Money or easier work. My unit was converted from Rehab patients, to medicine which was a huge change in acuity. Overnight we were at 1:5 medicine ratios with no training or warning. Patients were assigned from some person in an office somewhere and we lost control of our bed board, room assignments, and ability to speak out against this practice. ER patients were brought up and dumped off with no report or warning and little to no work up done prior to arrival. Since many of our competitors were paying more hourly plus sign on bonuses, the staff left. There was no feeling of mutual respect or loyalty left. Moral was in the toilet. Safe harbor became the norm.
