ok,I would not have put in that I worked when if fact you did not.
There probably is a clause that states gaurenteed hours, but, if you don't work the scheduled hours, you can ask to make up the hours on another day. That would be your 40 hours.
BUT anyway, no, the hospital won't pay if you were not there and the company won't either.
SO, don't expect that money and Learn from this.
I was scheduled to work 40 hours for my first week of orientation but only worked 32 because we got done early each day. I submitted the hours I worked and Oh well, lose out on 8hours...Another nurse put 40 hours on her time card, even tho, it was 32. I would not do that.
