Heh...you know, when I used to work, I was was a per diem employee by choice...they'd call me and I'd work as needed. I had a seperate ring on my phone so if I didn't want to work, I just wouldn't answer the phone.
Well, my ex-boss called me and I decided I wanted to work so I answered the phone. She said she'd had a number of people call in sick and would I mind filling in? "OK, sure!" says I.
Then she just proceeds to bawling me out, saying I needed to let her know every two weeks what days I intended to work (not a requirement of per diem employment). "Ok, sure." says I.
I resigned that very night by typing a letter of resignation and slipping it and a copy of it under her door and the director of nursing's door. He he...gave two week notice and never worked for them again.
Per diem nurses work when they want...you don't go demanding a schedule from them. They have too many other options.
