I did not agree to on call when I was hired 6 years ago. As a matter of fact we used to get incentives to come in such as call back pay(two hours salary plus hours worked) if we came in. Then it was cut out and we were not allowed to call it "On Call " but had to call it "Stand By". Which leads me to believe it is not a job requirement but a request. It happens all the time. On days I am scheduled to work, I may get called off and asked to be on Stand by. You can say no, but it is held against you in a personal way. No one says no. Today I worked. I am off tommorrow. The assistant nurse manager ask me if I would be on call (She is supposed to be on call). I said no. I am sure I will be punished in some form or another. Thanks for the reply, Nancy
