Mandations for CNA

I'm not sure if

You being a student has nothing to do with your employment. It is YOUR (and only your) responsibility to make sure you are practicing safely.

Unless you have a contract with your employer that states that they'll work around your school schedule, then they don't have to. You aren't a slave. Your employer can't force you to be there. If your job and school schedules conflict, YOU must resolve this. And you might find that you may not get everything you want. You may have to find another job or put school on hold. But do what you have to do to practice responsibly and safely.

Student or other personal obligations have zero baring on mandated shifts

I don't know if it was law, but per my contract as a CNA I could be mandated, even though officially I was part-time employee and a student. I knew that was a risk when I took the job and the circumstances under which my employer could mandate. However, likelihood of being mandated as a CNA was low on my unit.

Your class schedule is completely irrelevant to the needs of the unit and their mandating practices. If the law says anything, it probably only says how many hours you can be mandated for. I believe in my state, you cannot work more than 16 hrs in a 24 hr period.

We didn't mandate aides with I worked in the hospital as the unit could and did function without them. Nurses were rarely mandated because usually someone made a deal for something that worked for them and volunteered to stay. But if it was your turn to be mandated, it wouldn't matter if you were in school or not.

I have seen CNAs who have refused to be mandated due to "hardships",tho I don't know what those hardships were. The penalty was the same as if they had called off a shift and a 3 suspension.

I have also heard you can loose your certification for refusing to stay when mandated.
