I take this to mean you need one less day nurse, and one more night nurse? If I were DON, I would hold a staff meeting, to tell the staff that you are facing a situation, and why (be frank) , and then ask if any day nurses want to move to nights. Or any 3-11 want to move to nights, and then if any day shift nurse wants to move to 3-11. Or, you might even be suprised at solutions that might be offered up. If nobody jumps, you can then hire a night nurse, while informing your staff that in that event, a day nurse will be laid off- based on seniority, in my opinion. Fair, open, transparent, the way to minimize pain all around. I don't envy you. But I also wouldn't want to see you alienate staff, and cause more pain that must be caused? And even though nurses are a dime a dozen anymore, with no jobs to go around...being frank, honest, appreciative, rather than heavy handed, will do nothing but make your job easier?
