I work for an agency which has the RN's work 1 night on call per week *they will usually put a SOC or ROC etc on them that night*. Then they have a weekend "on -call". That Fri 4:30pm thru Mon morning7:59am. They will put a SOC/ ROC Fri night, 2 SOC\ROC's Sat, as well as 2 or 3 routines, and of course any PRN visits that are actually on-call. Then Sun another 2 SOC/ROC's and possible routines.
This, broken down from the RN's side of things is: work 12 days in a row every 4th week. Considering that we case manage and do routines, take 'call', etc., the bottom line is that it is too much.
5 nurses quit in a 3 month time period. We have become a revolving door.
