Welcome to the site!
Sounds like you made a wise decision to leave the office; hope you kept a copy of your resignation, cuz if things happen.... Just to be curious, are you in the Northern, Central, or Southern part of the state?
As for the 5 nurses getting the axe in 3 months: has there been a change in Administration or a new DON lately? Sounds like we've got some talking to do!
