24hrs is just cray cray

I worked in a hospital, and we only had to give a couple hours notice before the start of our shift. And, we were all considered "essential personnel" ... so even during extreme weather conditions, we were expected to get to work, somehow.

You could probably take it to HR ... but, depending on the politics of your company, you may find that HR is only going to side with the dept manager. But, I'd certainly ask them if some kind of medical rider could be implemented in your case.
