Wow, all of you are super lucky, check THIS out...
They took away our "on-call" and substituted it with "voluntary off" or "VO". Let's say I'm scheduled to work Tuesday with four other nurses, five total, and the census only demands four nurses. If it's mine turn to be "VO'd", then they will call me, no later than 2 hours prior to my shift beginning, and tell me I'm "VO'd". This means that as of right now, I am not working. They VO in blocks of four hours. So, that means (for me, at least), that I am off from 1900-2300. However, I can be called in as late as 1930 if needed, otherwise the call would be to tell me that I'm needed at 2300.
The key is, there is NO compensation for being called off and then required to wait by the phone. They purposely instituted this new approach to get out of paying the nurses on-call pay.
The real killer is when you're VO'd until 2300, then they don't need you at 2300...but then you get that nasty little call at 2330 to come in. OR, even worse yet, is when you get the call at 0130 that you're needed at 0300!!! That's right!!! They can call you in 2/3 of the way through your night shift!
So, you guys need to be glad that you get paid to be waiting there, like an idiot, because we don't. And actually, I'm pretty sure it's not legal, but I need to further prove that.
