Called Off again....and scared!

I haven't asked the manager yet (but I do intend to when I am back on Friday). I was supposed to have a training session with the staff educator today and I wouldn't have been working on the floor for a good portion of the day... so I really don't understand why I couldn't be there.

Thanks everyone for the replies. To clarify some questions that posters had....

1. It is not a union hospital.
2. I did tell the person who called me that I am in orientation and that I was scheduled to meet all afternoon with the staff educator. Apparently none of that mattered because she told me I would just have to reschedule.
3. I am willing to work different shifts....in fact, I am trying to get on 2nd or 3rd shift but the supervisor won't let me work a different shift until my orientation is complete...and, no, they have no idea when that will be.

To be honest, in general my orientation has been less than helpful. This is my first aid job and they basically put me out on the floor and had me work with another aid (who didn't do much or help me). I have basically been "on my own" and since I am not getting the orientation I feel I deserve I might as well not be on orientation and then I could work different shifts. I don't know if it is like this at other hospitals but I sure hope not. I have an interview tomorrow at a different hospital but it is for a per diem position and I don't know if it will be the same disaster all over.

I feel so frustrated and I have just hit the tip of the iceburg on my nursing journey....
