Floated again

Look, I'm all for being a team player, but getting floated to a different unit every other shift is driving me insane. I didn't train in neuro to get thrown into geriatrics at the drop of a hat. I don't know those patients, their procedures, or their routines. It's unsafe for them and it's unfair to me. Surely there's a better way to manage staffing instead of trading us around like we're baseball cards?
