Our ICU nurses rarely float due to a normally high census but.....our facility has a float policy. I have had ICU nurses float to one of my med/surg units without any problems. I have also had ICU nurses float to tele and then float a tele nurse to the med/surg floor. It usually depends on which nursing supervisor is working and is usually her decision. Maybe you can get a team together and develop a float policy. Get some staff from each unit involved. Good luck!
