When I first started working as a nurse, the manager who hired me was just the best. There wasn't a nurse in that entire unit who didn't like her, and our unit was tight and very well run. When the floor got real busy she would walk around and help out with patient care, passing meds, etc. Because she was so accommodating, there wasn't one favor she would ask that the staff wouldn't do. Morale was great, and we never had staffing issues because people were always willing to come in to work extra. That lady was one really awesome boss. Always went to bat for her nurses.
Unfortunately, due to some pretty nasty politics, higher management forced her out of the position and brought in a new manager who, I genuinely believe, is possessed by the Devil. This woman was so nasty and despicable that most of the nurses eventually left. Everyone knew that she got the position because of a 'relationship' she had with one of the medical directors. She had no respect for any of us and told us straight out in a staff meeting that if we don't like the changes she's going to be making she would be happy to accept our resignations. She began messing with the schedules, cancelling people's vacations, writing up people if they called in because their kids were sick, telling people she would no longer consider their scheduling requests to accommodate school, etc. Then she fired the assistant nurse manager and brought in her friend, who walked the floors all day long looking for every little excuse to write up any nurse she didn't like.
Things got pretty bad real quick, and she lost a whole group of really good nurses. I heard that was her strategy anyway because she figured her budget would look much better if she hired all new grads and pay them salaries at the lowest end of the scale. She didn't like men and she was also a racist, and from the people she targeted for the ridiculous write-ups it was obvious that she was cleaning house.
Couldn't get out of that place fast enough!
