I know this is late, but I just saw this post... or possibly I forgot to respond, not sure which one. Anyway, Yes I worked as a CNA while in nursing school. However, I worked per diem which in my hospital meant I chose my schedule, I just had to work 4 shifts a month. That is totally doable. Also, I could cancel my shift and reschedule as long as it was 24 hours before the shift started (or something like that). I would not recommend full time CNA or even part-time CNA simply because usually even part time is 2 days a week and it's not really flexible. You are part of a unit and you need to be a team player. I was just float so I filled in wherever.
